to the compiler to test its capabilities; see:

9ff4167c8c linux: explain why we need host-{flex, bison}
The commit that added the dependency on host-{bison,flex} did
so because the pre-generated kconfig parser source files were
removed from the kernel tree, in linux-4.16.

But then, in linux-4.17, the pre-generated dtc parser source
files were in turn removed as well.

So, document the two reasons why they are needed, so we don't
accidentally remove them when we (soon) introduce the kconfig
dependencies.

(Also fix the first assignment to LINUX_DEPENDENCIES to be a
simple assignement, not an append-assignment.)

1b53b177a6 linux: replace shell for loop with make foreach loop
This commit replaces the loop copying out-of-tree DTS into the kernel
tree by a make foreach loop instead of a shell for loop. This allows
to error out if one of the DTS file cannot be copied (for example if
it doesn't exist).

9a50447b5d linux: disable attribute alias with gcc >= 8.1
gcc-8 started warning about function aliases that have a non-matching
prototype. This seems rather useful in general, but it causes tons of
warnings in the Linux kernel, where we rely on abusing those aliases
for system call entry points, in order to sanitze the arguments passed
from user space in registers.

See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82435

Disable the attribute-alias warning introduced by gcc-8 by adding
-Wno-attribute-alias to KCFLAGS.

c2c0623bff linux: may fail to boot for binutils 2.29+ even without armv7m
Commit f13477b (linux: config.in: add comment for Arm Cortex-M) added a
comment so that the user that the linux kernel may miscompile with
binutils 2.29+, when the target is an armv7m CPU.

However, the real trigger is a compilation in thumb2 mode, which happens
to be the only option for armv7m CPUs.

We can't know whether the kernel will be built in arm or thumb2 mode,
though, because we do not have that information: it is only available in
the Linux' .config file, which we don;t have access to at the time we
run our menuconfig.

So, relax the conditions under which the comment is made, so that it
appears as soon as binutils are >= 2.29 (i.e. not 2.28, which is the
oldest we support) for ARM CPUs.

6d3d09e232 linux: don't override HOSTCC for kconfig
Kconfig uses either pkg-config or hard-coded /usr/include paths to find
the ncurses or ncursesw library. If ncursesw is found, it will include
<ncursesw.h>. Since Buildroot's host-ncurses doesn't install a .pc file,
and linux.mk anyway doesn't pass the pkg-config options to find the host
pkg-config files, Kconfig will always find the system's ncursesw.h.

However, since commit dde090c299 (linux: fix passing of host CFLAGS and
LDFLAGS) HOST_LDFLAGS is passed to the linux build system. Thus, if
host-ncurses was already built before 'make linux-menuconfig' is called,
the build will pick up libncurses from the host directory, which is NOT
widechar. Thus, two different ncurses configurations are mixed into the
final mconf program. This will result in serious breakage in the
rendering of the menus (lots of @ and question mark characters).

As a workaround (suggested by Yann), don't pass HOST_CFLAGS and
HOST_LDFLAGS when running kconfig commands. For kconfig, we should never
need host packages anyway. This way, the kconfig calls will always use
the system's ncurses and never our host-ncurses.

Note that the same problem could pop up for other kconfig packages as
well if we ever pass HOST_CFLAGS/HOST_LDFLAGS to them. We could force
HOSTCC=$(HOSTCC) directly in kconfig-package. However, for now there
are no other packages that exhibit this problem, so this can be
revisited when they do.

f7cd72b3d4 linux: add BR2_LINUX_KERNEL_NEEDS_HOST_LIBELF
Some Linux kernel configuration options (such as CONFIG_UNWINDER_ORC)
require building a host program that needs libelf.

Users who have libelf installed on their system won't see a problem,
but users who don't have libelf installed will get a build
failure. Therefore, this commit adds an option that allows a user to
indicate that his Linux kernel configuration requires libelf. When
this option is enabled, we add host-elfutils to the dependencies of
the linux package (host-elfutils provides the libelf library).

93a7edf4bc linux: add BR2_LINUX_KERNEL_NEEDS_HOST_OPENSSL
Some Linux kernel configuration options (such as
CONFIG_SYSTEM_TRUSTED_KEYRING) require building a host program called
extract-cert, which itself needs OpenSSL.

Users having OpenSSL installed on their system won't see a problem,
but users who don't have OpenSSL installed will get a build
failure. This commit adds a new option that allows users to indicate
that their Linux configuration requires building host-openssl.

dde090c299 linux: fix passing of host CFLAGS and LDFLAGS
We were passing HOSTCFLAGS="$(HOSTCFLAGS)" to Linux. However:

 - HOSTCFLAGS in Buildroot doesn't exist, and is empty, so this
   assignment never did anything. The name of the variable in
   Buildroot in HOST_CFLAGS.

 - HOSTCFLAGS in Linux isn't used everywhere, and passing it overrides
   the default HOSTCFLAGS value defined in the main Linux kernel
   Makefile.

In addition, there is no way to pass additional host LDFLAGS in the
Linux kernel build system.

Therefore, we simply shoehorn our HOST_CFLAGS and HOST_LDFLAGS while
passing HOSTCC to the Linux kernel build system. This has been tested
to work fine with host OpenSSL and host libelf only available in
$(HOST_DIR).

cef77a6cf5 linux: meddle not in the internals of filesystems
Currently, the rule to rebuild the Linux kernel with an initramfs
directly depends on the path of the file of the intermediate cpio image.

This is inherently "bad" from a purity point of view; linux.mk should
not have to delve into the fs internals.

Rather, make it directly depend on the "frontal" rule that generates the
cpio image.

Drop the comment for linux-rebuild-with-initramfs, it was misleading
(talking about generating "the initramfs list of files", which is not
what was done, since we use a cpio as source of initramfs, not a list of
files).

712f81fb3c linux: Deselect all unconfigured compression options
The LINUX_KCONFIG_FIXUP_CMDS are meant to deselect any compression
option that are not selected in the buildroot configuration. But it only
deselects the last one in the list instead of all of them because it
overwrites the LINUX_COMPRESSION_OPT_ variable instead of appending to
it. Only the last option set to that variable gets deselected.

This produces the warning:

.config:2216:warning: override: KERNEL_GZIP changes choice state

is emitted when buildroot runs olddefconfig when buildroot configures a
kernel with a custom config that has a different kernel compression
option set to what is configured in buildroot.

Accumulate all the deselected compression options instead of overwriting
them to ensure all non-selected options get deselected..

ba0a5b11d9 linux: exclude from hash check except for latest version
We don't have a hash for any linux version. We currently also don't
have a hash for the latest version, but if we ever add a hash, it
will only be for the latest version.

This simplifies the code a little because soon we will add hash checks
for git as well, so we also need an exclusion in that case. It's much
easier to always exclude except in the single case where we do have a
hash.

ee995b1819 linux: select BR2_PACKAGE_HOST_UBOOT_TOOLS instead of BR2_LINUX_KERNEL_UBOOT_IMAGE
A long time ago, the blind config option BR2_LINUX_KERNEL_UBOOT_IMAGE
was introduced to be able to trigger the linux -> host-uboot-tools
dependency. Back in those days, there was no user-configurable
BR2_PACKAGE_HOST_UBOOT_TOOLS.

Now, however, it is possible to select a custom kernel image name that
needs uboot-tools, and manually enable BR2_PACKAGE_HOST_UBOOT_TOOLS. In
this case, however, the linux -> host-uboot-tools is missed and the
build is not reproducible. An example of such a situation is the
upcoming CI40 defconfig.

As a solution, remove BR2_LINUX_KERNEL_UBOOT_IMAGE entirely. Instead,
just select BR2_PACKAGE_HOST_UBOOT_TOOLS and add the dependency if it
is selected.

Note that this may introduce a redundant dependency in case the user
selected BR2_PACKAGE_HOST_UBOOT_TOOLS for some other reason (e.g. to
be able to generate a U-Boot environment to include in the image, while
the kernel is built as a zImage). However, the redundant dependency
shouldn't hurt much.

10fc02b984 linux: generate KBUILD_BUILD_TIMESTAMP date whith LC_ALL=C
Fix kernel reproducible build if a non-C locale is used on the host
system.

When building the Linux kernel, scripts/gen_initramfs_list.sh does 'date
-d"$KBUILD_BUILD_TIMESTAMP" +%s'. In linux.mk, Buildroot sets
KBUILD_BUILD_TIMESTAMP to "$(shell date -d @$(SOURCE_DATE_EPOCH))".

For example, if LANG=fr_FR.UTF-8 is defined in the host system, it does
not work:

- LC_ALL=C date -d"$(LC_ALL=C date)" : ok
- LC_ALL=C date -d"$(LC_ALL=fr_FR.UTF-8 date)" : error

LANG/LC_ALL variables exported in the main Makefiles are not passed in
the $(shell ...) sub-shells.

20b1446669 linux/tools: make it a real, separate package
The kernel source tree also contains the sources for various userland
tools, of which cpupower, perf or selftests.

Currently, we have support for building those tools as part of the
kernel build procedure. This looked the correct thing to do so far,
because, well, they *are* part of the kernel source tree and some
really have to be the same version as the kernel that will run.

However, this is causing quite a non-trivial-to-break circular
dependency in some configurations. For example, this defconfig fails to
build (similar to the one reported by Paul):

    BR2_arm=y
    BR2_cortex_a7=y
    BR2_ARM_FPU_NEON_VFPV4=y
    BR2_TOOLCHAIN_EXTERNAL=y
    BR2_INIT_SYSTEMD=y
    BR2_LINUX_KERNEL=y

    BR2_PACKAGE_LINUX_TOOLS_CPUPOWER=y
    BR2_PACKAGE_CRYPTODEV=y
    BR2_PACKAGE_OPENSSL=y
    BR2_PACKAGE_LIBCURL=y

This causes a circular dependency, as explained by Thomas:

 - When libcurl is enabled, systemd depends on it

 - When OpenSSL is enabled, obviously, will use it for SSL support

 - When cryptodev-linux is enabled, OpenSSL will depend on it to use
   crypto accelerators supported in the kernel via cryptodev-linux.

 - cryptodev-linux being a kernel module, it depends on linux

 - linux by itself (the kernel) does not depend on pciutils, but the
   linux tool "cpupower" (managed in linux-tool-cpupower) depends on
   pciutils

 - pciutils depends on udev when available

 - udev is provided by systemd.

And indeed, during the build, we can see that make warns (it's only
reported as a *warning*, not as an actual error):

    [...]
    make[1]: Circular /home/ymorin/dev/buildroot/O/build/openssl-1.0.2h/.stamp_configured
    <- cryptodev-linux dependency dropped.
    >>> openssl 1.0.2h Downloading
    [...]

So the build fails later on, when openssl is actually built:

    eng_cryptodev.c:57:31: fatal error: crypto/cryptodev.h: No such file or directory
    compilation terminated.
    <builtin>: recipe for target 'eng_cryptodev.o' failed

Furthermore, graph-depends also detects the circular dependency, but
treats it as a hard-error:

    Recursion detected for  : cryptodev-linux
    which is a dependency of: openssl
    which is a dependency of: libcurl
    which is a dependency of: systemd
    which is a dependency of: udev
    which is a dependency of: pciutils
    which is a dependency of: linux
    which is a dependency of: cryptodev-linux
    Makefile:738: recipe for target 'graph-depends' failed

Of course, there is no way to break the loop without losing
functionality in either one of the involved packages *and* keep
our infrastructure and packages as-is.

The only solution is to break the loop at the linux-tools level, by
moving them away into their own package, so that the linux package will
no longer have the opportunity to depend on another package via a
dependency of one the tools.

All three linux tools are thus moved away to their own package.

The package infrastructure only knows of three types of packages: those
in package/ , in boot/ , in toolchain/ and the one in linux/ . So we
create that new linux-tools package in package/ so that we don't have to
fiddle with yet another special case in the infra. Still, we want its
configure options to appear in the kernel's sub-menu.

So, we make it a prompt-less package, with only the tools visible as
options of that package, but without the usual dependency on their
master symbol; they only depend on the Linux kernel.

Furthermore, because the kernel is such a huge pile of code, we would
not be very happy to extract it a second time just for the sake of a few
tools. We can't extract only the tools/ sub-directory from the kernel
source either, because some tools have hard-coded path to includes from
the kernel (arch and stuff).

Instead, we just use the linux source tree as our own build tree, and
ensure the linux tree is extracted and patched before linux-tools is
configured and built.

10c4d27aef linux: use INSTALL_MOD_STRIP=1 to strip modules
We used to do a special handling of Linux kernel modules when stripping
target binaries because there's some special precious data in modules
that we must keep for them to properly operate. This is for example true
for stack unwinding data etc.

It turned out there're cases when our existing "strip --strip-unneeded"
doesn't work well. For example this removes .debug_frame section used by
Linux on ARC for stack unwinding, refer to [1] and [2] for more details.

Now Linux kernel may strip modules as a part of "modules_install" target
if INSTALL_MOD_STRIP=1 is passed in command line. And so we'll do
allowing kernel decide how to strip modules in the best way.

Still note as of today Linux kernel strips modules uniformly for all
arches with "strip" command, so this commit alone doesn't solve
mentioned problem but it opens a possibility to add later a patch to the
kernel which will strip modules for ARC differently - and that's our
plan for mainline kernel.

e782cd5b1b Revert "Added local directory as source of kernel code"
This reverts commit 73da2ff6f7.

The reason for adding support for a local location was to be able to do
development on the Linux kernel source tree on a local directory rather
than have to clone it for every build.

We already have a mechanism for that, it's called override-srcdir. It's
been available since September 2011, more than a year before this patch
was committed.

Otherwise, we're going to be adding support for local sources in other
packages. First was U-Boot as submitted by Adam. But what next? We can't
have such support for all packages, especially since override-srcdir
does the job.

Besides, using a local source tree makes the build non-reproducible, so
we don't really want to have this in a .config (or defconfig).

We only handle the boolean option in legacy, as there is nothing we can
do with the directory path.

f55adea434 linux: cpupower needs gettext
The cpupower linux tool needs gettext, always (even without locales).

We need to disable NLS, otherwise it tries to compile the .po files.
We also need to pass -lintl, otherwise it forgets to link with it
(because, the world is glibc-only, you did not know? And glibc does not
need we link with -lintl, so why would we? Oh, yes, we also reinvented
our super intelligent one-off Makefile rather than use one of the
standard buildsystems).

53ced1f6d3 linux: allow the selection of the architecture's default configuration
To configure the Linux kernel, we currently provide two options:

 1. Passing a defconfig name (for example "multi_v7"), to which we append
    "_defconfig" to run "make multi_v7_defconfig".

 2. Passing a path to a custom configuration file.

Unfortunately, those two possibilities do not allow to configure the
kernel when you want to use the default configuration built into the
kernel for a given architecture. For example, on ARM64, there is a
single defconfig simply called "defconfig", which you can load by
running "make defconfig".

Using the mechanism (1) above doesn't work because we append
"_defconfig" automatically.

One solution would be to change (1) and require the user to enter the
full defconfig named (i.e "multi_v7_defconfig" instead of "multi_v7"),
but we would break all existing Buildroot configurations.

So instead, we add a third option, which simply tells Buildroot to use
the default configuration for the selected architecture. In this case,
Buildroot will configure the kernel by running "make defconfig".

690ed04845 linux: provide symlink dtc->linux-dtc is there is no dtc yet
Commit ab74e09eb4 renamed the dtc host tool
provided by linux to linux-dtc to avoid clashes with the dtc host tool
provided by host-dtc.

However, external scripting may well rely on the existence of a device tree
compiler as $(HOST_DIR)/usr/bin/dtc, regardless of its source. Changing
these external scripts to use linux-dtc means that the scripts need to be
aware of the buildroot release they are working with, which is not very
nice.

Add a symlink dtc->linux-dtc when no $(HOST_DIR)/usr/bin/dtc is present.
When host-dtc is not enabled, the end result will be dtc and
linux-dtc representing the same thing.
When host-dtc is enabled, either it is build before linux and no symlink
is created at any time, or it is build after linux, and the 'install'
command in host-dtc will overwrite the symlink with a proper dtc. In both
cases, the end result will be dtc and linux-dtc representing a different
thing.

5c67cb1d04 linux: use zImage by default on ARM
Since quite some time, the kernel and bootloader communities consider
zImage as the default format for kernel images on ARM, replacing
uImage. The load address information in uImage is no longer needed,
since the kernel is position-independent in terms of physical address,
except on a few old platforms. For most people, using zImage is simply
better/simpler, so let's switch to zImage as the default image format
on ARM.

All defconfigs are updated: 46 defconfigs no longer need to select
explicitly zImage because it's the default, and 16 defconfigs now need
to explicitly select uImage because that's no longer the default.

8143721c3e linux: build and install kernel selftests
This patch adds the ability to compile and install the kernel
selftests into the target at /usr/lib/kselftests. The rationale behind
/usr/lib is that the selftests have subdirectories where they are
installed which makes them unsuitable to be placed in /usr/sbin as
this would result in /usr/sbin/kselftests/x/y/z. While the selftests
aren't libraries either, they don't achieve much as a standalone
binary so they can be considered to be a 'library of tests' making
/usr/lib sensible.

The selftests require that the kernel headers be installed into the
kernel build tree as some of the selftests have a hardcoded CFLAGS to
include kernel headers (CFLAGS += -I../../../../usr/include/). This is
most easily achieved by using the make ... headers_install inside the
kernel build dir.

This is likely to be a rarely used debugging/performance feature for
development and unlikely to be used in a production configuration.

c306e0493a linux/perf: really do not build the documentation
The perf buildsystem, inside the kernel, is not really amenable to be
easily used...

Regarding the documentation, it will forcefully try to detect asciidoc
and, with the latest versions, xmlto, completely disregarding what the
user may provide.

We currently pass ASCIIDOC= (the empty string) on the make command line,
as an attempt to disable building the documentation, but that has no
effect whatsoever on perf: that variable is not passed down to the
sub-sub-make (yes, a two-level depth) that is responsible for building
the documentation.

We really do not want to build any of the documentation (the user can
refer to the documentation on his own development machine), so we use a
little dirty trick: we provide a GNUmakefile beside the existing
Makefile for the documentation; GNUmakefile always takes precedence over
a Makefile when both are present. We only provide a catch-all-no-recipe
rule in that GNUmakefile, so it really does nothing useful, except avoid
building the documentation.

d6a5d71aba linux: add conditional patch for timeconst.pl
Kernels older than 3.9 (not counting stable releases) used the
timeconst.pl perl script for their build process.
The problem with this script is that it used deprecated perl features,
namely defined(@array) which was removed for the perl 5.22 release,
causing build failure of older kernels on newer distributions.

To fix this instead of going the hard way (moving to the new
timeconst.bc script) use the easy way by patching timeconst.pl with an
upstream patch used for stable releases.

First try a dry-run on the patch to see if it applies, if it does then
call a proper APPLY_PATCHES to it.

Tested against an arbitrary 2.6.30 kernel (applies and builds), against
4.4.1 for a missing timeconst.pl (does not apply since it's missing) and
3.8.13 (does not apply since it's fixed already).

Known broken distributions: fedora 23, debian testing (stretch) and unstable
(sid).

da4fff547c kernel-module-imx-gpu-viv: add new package
This is the Vivante kernel driver split from the kernel source code in
order to make it possible to be used in any kernel source since 3.10.53.

The driver source code provided by Freescale needs fixes so the
community forked the code to allow faster development and easier
integration of fixes from the community.

This patch is based on the Yocto equivalent:
https://github.com/Freescale/meta-fsl-arm/commit/32cf391
https://github.com/Freescale/meta-fsl-arm/commit/4249193

63abfb7210 package/linux-headers: add option to use same sources as the kernel
Some heavily (and most often improperly) modified Linux kernels may export
new APIs to userland, so as to speak to custom hardware or custom kernel
facilities.

However, we currently have no easy way to use such kernels as a source
for the linux-headers package, which precludes having those userland
headers intalled for userland applications to use them.

We do have a way for the kernel to use the same version as for the
headers, but that is definitely not enough, as the linux-headers package
has a version choice that is far less versatile and capable than that of
the linux package.

Add a new option for the linux-headers package, for the user to specify
that the version (really, the sources) of the kernel be used to install
the headers from.

We do that by making linux-headers patch-depend on the linux package.

We can't have linux-header simply depend on linux, because the simple
dependency means the the dependee will be configured, built and installed
before the dependent is configured. And since linux is a target package,
it depends on the toolchain, which internally dependes on linux-headers,
which would depend on linux, and we'd get a circular dependency.

Using patch-depend will ensure that linux is extracted and patched
before linux-headers is extracted, which is really all we need.

Then, we install the headers from the linux source tree, rather than
from linux-headers' source tree (as there's nothing in there!).

Since we need to install a private set for uClibc (see cde947f, uclibc:
prevent rebuilding after installation to staging), we explicitly set
INSTALL_HDR_PATH when calling the kernel' install-headers rule in
LINUX_HEADERS_CONFIGURE_CMDS, so that the headers are installed in
linux-headers' $(@D) instead of linux' $(@D).

Finally, as there is no way to know the kernel version in this case, we
must still prompt the user for the kernel series the headers are from
(like we do for a custom version) and check for consistency at build
time.

Note however that this still leaves users that want to built their
such-kernel outside of Buildroot out in the cold.

5471bac748 linux: add blind kconfig option to require kernel modules
Currently, packages that need the kernel to have support for laodable
modules have two ways to require it:

  - either the use the kernel-module infra, which does it automatically,

  - or they do not use it, and they need to require it manually by
    setting the corresponding Makefile variable; however, they must only
    set it when they are actually enabled, which makes for a slightly
    cumbersome and ugly code, like:

        ifeq ($(BR2_PACKAGE_FOO),y)
        LINUX_NEEDS_MODULES = y
        endif

Introduce a new blind Kconfig option that packages can select to signify
they need kernel modules. That Kconfig option is then used to set the
Makefile variable.

It makes it cleaner:

  - code is simpler (one Kconfig line instead of a Makefile if-block,

  - this is handled at the Kconfig level, which is where we usually
    handle such dependencies.

Packages will be updated in follow-up commits.

055e6162bb linux: don't build appended DTB image in place and support multiple images
Currently, the linux.mk logic for appended DTB image does the
appending of the DTB in place, directly at the end of the zImage using
a >> sign. This is incorrect because if you run "make linux-rebuild"
multiple times, you get the DTB appended over and over again to the
image.

Since keeping the 'zImage' or 'uImage' name for the appended DTB image
is not very clear, this commit moves to using the 'zImage.<dtb>' and
'uImage.<dtb>' format. This way, we can clearly distinguish the
original image from the appended one.

In addition, this naming scheme easily allows to generate *multiple*
appended DTB images: from one zImage, you can generate multiple
zImage.<dtb> for several DTBs, and then generate (if requested) the
corresponding uImage.<dtb>.

To achieve this, this commit:

 - Changes the definition of LINUX_APPENDED_DTB to iterate over
   $(KERNEL_DTS_NAME), and generate a zImage.<dtb> image for each of
   them.

 - Changes the addition of LINUX_APPENDED_DTB for appended uImage to
   also iterate over $(KERNEL_DTS_NAME).

 - Provide a different implementation of LINUX_INSTALL_IMAGE which
   installs all the appended DTB images (but not the bare image)

 - Remove the checks that verified that only one DT name is passed
   when appended DTB is used, since we now support generating multiple
   DT images.

Some of the tested configuration:

 - Normal uImage with several DTBs

   BR2_LINUX_KERNEL_DEFCONFIG="mvebu_v7"
   BR2_LINUX_KERNEL_UIMAGE=y
   BR2_LINUX_KERNEL_UIMAGE_LOADADDR="0x200000"
   BR2_LINUX_KERNEL_DTS_SUPPORT=y
   BR2_LINUX_KERNEL_INTREE_DTS_NAME="armada-xp-matrix armada-xp-gp armada-370-mirabox"

   Contents of output/images/:

   armada-370-mirabox.dtb  armada-xp-gp.dtb  armada-xp-matrix.dtb  uImage

 - Normal zImage with several DTBs

   BR2_LINUX_KERNEL_DEFCONFIG="mvebu_v7"
   BR2_LINUX_KERNEL_ZIMAGE=y
   BR2_LINUX_KERNEL_DTS_SUPPORT=y
   BR2_LINUX_KERNEL_INTREE_DTS_NAME="armada-xp-matrix armada-xp-gp armada-370-mirabox"

   Contents of output/images:

   armada-370-mirabox.dtb  armada-xp-gp.dtb  armada-xp-matrix.dtb  zImage

 - Appended uImage with several DTBs:

   BR2_LINUX_KERNEL_DEFCONFIG="mvebu_v7"
   BR2_LINUX_KERNEL_APPENDED_UIMAGE=y
   BR2_LINUX_KERNEL_UIMAGE_LOADADDR="0x200000"
   BR2_LINUX_KERNEL_INTREE_DTS_NAME="armada-xp-matrix armada-xp-gp armada-370-mirabox"

   Contents of output/images:

   uImage.armada-370-mirabox  uImage.armada-xp-gp  uImage.armada-xp-matrix

 - Appended zImage with several DTBs:

   BR2_LINUX_KERNEL_DEFCONFIG="mvebu_v7"
   BR2_LINUX_KERNEL_APPENDED_ZIMAGE=y

   Contents of output/images:

   zImage.armada-370-mirabox  zImage.armada-xp-gp  zImage.armada-xp-matrix

24745cb4be linux: only install the DTBs when not in appended DTB mode
When you're using the "appended DTB" mode, the Device Tree blob gets
appended to your kernel image, so there is no point in installing both
the DTB and the kernel image to the images or target directories,
installing the kernel image itself is sufficient.

Therefore, this commit disables the definition of LINUX_INSTALL_DTB
when appended DTB is used.

55b80d3bb9 linux: de-duplicate DTB and Linux image installation
Currently, the LINUX_INSTALL_DTB and LINUX_INSTALL_DTB_TARGET macros
are exactly the same, except for the target directory.

Similarly, LINUX_INSTALL_KERNEL_IMAGE_TO_TARGET and
LINUX_INSTALL_IMAGES_CMDS are copying the kernel image, just to a
different place (and with a different strategy).

As a preparation for future additions, this commit de-duplicate this
code:

 - LINUX_INSTALL_DTB becomes a make macro that takes one argument: the
   destination directory.

 - LINUX_INSTALL_IMAGE is a new make macro that also takes on
   argument: the destination directory.

Both macros are used by LINUX_INSTALL_KERNEL_IMAGE_TO_TARGET and
LINUX_INSTALL_IMAGES_CMDS to respectively install to the target
directory and the images directory.

Although the current code does enable them in the linux' .config file,
the former is protected behind CONFIG_NETFILTER_ADVANCED, which may be

The Linux buildsystem tries to run the compiler even just for
'kernelrelease' (which we store in LINUX_VERSION_PROBED) and we
sometimes need to use it before the toolchain is available; thus
we get spurious errors on stderr.

Consign stderr to oblivion when computing the 'kernelrelease'.

90d008ea7a linux: adjust fixup logic for ktap
The ktap package requires some parts of the kernel tracing
infrastructure to be enabled, especially
CONFIG_EVENT_TRACING. However, this option is a blind option in the
kernel, so enabling it in linux.mk has no effect: we need to enable a
non-blind option that selects CONFIG_EVENT_TRACING. We've chosen to
select CONFIG_ENABLE_DEFAULT_TRACERS.

This fixes the build of ktap.

e7035d4eb9 rtai: remove option BR2_LINUX_KERNEL_EXT_RTAI_PATCH
This commit removes BR2_LINUX_KERNEL_EXT_RTAI_PATCH because this
option never worked. It was added in commit
8797a9cd1f, which added package/rtai/
and RTAI as a Linux extension.

The option prompt says "Path for RTAI patch file", so let's say you
specify /home/foo/bar/myrtai.patch as the value for
BR2_LINUX_KERNEL_EXT_RTAI_PATCH.

Then the code does:

RTAI_PATCH = $(call qstrip,$(BR2_LINUX_KERNEL_EXT_RTAI_PATCH))

and we have a package called 'rtai', so the normal logic of
<pkg>_PATCH applies. Since the <pkg>_PATCH value does not contain
ftp://, http:// or https://, the package infrastructure will try to
download $(RTAI_SITE)/$(RTAI_PATCH), i.e:

   https://www.rtai.org/userfiles/downloads/RTAI/home/foo/bar/myrtai.patch

Pretty clear that it has no chance of working.

Now, let's assume an URL is used as the value of
BR2_LINUX_KERNEL_EXT_RTAI_PATCH, such as
http://foo.com/bar/myrtai.patch. In this case, it will be properly
downloaded by the package infrastructure. But then, the following code
kicks in:

define RTAI_PREPARE_KERNEL
       $(APPLY_PATCHES)                        \
               $(LINUX_DIR)                    \
               $(dir $(RTAI_PATCH))            \
               $(notdir $(RTAI_PATCH))
endef

The value of $(dir $(RTAI_PATCH)) will be http://foo.com/bar/. How
can $(APPLY_PATCHES) make use of such a stupid patch location?

if we believe that no-one could have ever used this option.]

Curently, all three linux extensions follow the same layout:

  - add itself to linux' patch-dependencies
  - declare a macro, added as the pre-patch hook

Except for the macro, all can be commonalised.

Add a simple infrastructure for that:
  - extensions declare themselves in the list of extensions
  - extensions define their macro
  - the infra adds them to the patch-dependencies and pre-patch
    hooks as appropriate

53785a2c77 linux: fix extensions
Since the move to the kconfig-package infra, linux extensions are
broken.

In our linux package, extensions are applied as pre-patch hooks.

Before the kconfig-package infra, we had custom rules for the
linux-*config targets, which were of the form:

    linux-menuconfig: linux-configure
        $(MAKE) -C $(LINUX_DIR) menuconfig

This caused the linux tree to be fully configured before running the
configurators, and thus linux dependencies were entirely fullfilled, and
extensions were properly applied.

Since we migrated (in dff25ea), the kconfig-package infra introduces a
(hidden, internal) intermediate step 'kconfig-fixup' and decorelates the
kconfig-part of the configuration from the actual package-part of the
configuration:

    linux-configure -------> kconfig-fixup --> .config --> $(LINUX_CONFIG_FILE)
                        /
    linux-menuconfig --'

As thus, this (very useful!) use-case breaks (starting from a clean
Buildroot tree):

    make menuconfig
        -> enable a kernel and at least one extension
        -> save and exit
    make linux-menuconfig
        -> extensions are not available

Fix that by using the newly-introduced patch-dependencies, so that
extensions are available before we try to patch the linux kernel.

0eba4759fa packages: apply custom patches using *.patch instead of <pkg>-*.patch
Several packages have some logic to apply custom patches that existed
before the BR2_GLOBAL_PATCH_DIR mechanism: at91bootstrap,
at91bootstrap3, barebox, uboot and linux. Currently, the logic of
those packages to apply custom patches is to match
<package-name>-*.patch, which is not consistent with what we've done
for patches stored in the package directory, and for patches stored in
BR2_GLOBAL_PATCH_DIR: in such cases, we simply apply *.patch.

Therefore, for consistency reasons, this commit changes these packages
to also apply *.patch.

7430a41801 linux: use the package infrastructure to download patches
The linux package has a special handling of patches, with quite a bit
of legacy in it. A problem caused by this special handling is that the
linux package calls directly the DOWNLOAD_WGET macro, which means that
the package infrastructure isn't aware of which patches get
downloaded, and it prevents doing changes inside the package download
infrastructure.

This commit changes the handling of patches in the linux package in
the following way:

 * The LINUX_PATCHES variable is kept as is: it lists all the patches
   mentioned in the Config.in option BR2_LINUX_KERNEL_PATCH. This
   option can contain http://, ftp://, https:// URLs, path to local
   files or local directories.

   This variable is *not* used by the generic package infrastructure,
   so it is purely internal to the Linux package.

 * The LINUX_PATCH variable is now filled in with the list of patches
   that should be downloaded. It is derived from LINUX_PATCHES by
   filtering the patches that have http://, ftp:// or https:// in
   their path. Since <pkg>_PATCH is handled by the package
   infrastructure, it means that those patches are now automatically
   downloaded and applied by the package infrastructure.

 * The LINUX_APPLY_PATCHES hook is renamed to
   LINUX_APPLY_LOCAL_PATCHES, because it is now only responsible of
   applying local patches: remote patches are handled by
   LINUX_PATCH. The implementation of the hook is changed to filter
   out the patches that have already taken care of by LINUX_PATCH, so
   that we only iterate through the list of local patches or local
   patch directories.

This causes that user can't provide one *.dts file and some other

Problem is fixed by adding filter for initializing KERNEL_DTS_NAME
variable with *.dts files only. All user provided files are copied
into kernel source tree, but only file names suffixed with *.dts
are used for building appropriate *.dtb files.

00daf37c4f linux: avoid unnecessary changes in defconfig for INITRAMFS_SOURCE
When Buildroot is configured to append the root filesystem to the Linux
kernel as initramfs, Buildroot sets the path to the initramfs source
dynamically in the Linux configuration file.

As this path is specified as an absolute path, typically being different
for different users of the same project (e.g. containing a username),
saving the configuration to a version control system (for example using
'make linux-update-defconfig') would result in a difference for this
path at every invocation by a different user.
Although this is technically not an issue, it is confusing that this
generates a difference.

Address this issue by using a not-yet-expanded make variable to specify
the path to the initramfs source. That variable will be expanded by the
Linux build system, which uses it both as a Makefile variable and a
shell variable; thus, it needs to be specified in LINUX_MAKE_ENV (so
it is exported and available in sub-processes of make).  Any saved
configuration file would simply contain the reference to the
not-yet-expanded variable.

As in the Linux build system, the config variables are both read from
make as from a shell script, we cannot use $() syntax as this would be
interpreted as a command invocation by the shell. Instead, use ${}
syntax which is interpreted as variable reference both by the shell as
by make.

[Thomas:
 - Really make the patch work by using $(LINUX_MAKE_ENV) instead of
   $(TARGET_MAKE_ENV). Otherwise, the new BR2_BINARIES_DIR variable is
   not passed at all stages of the build process, which makes the
   build fail when an initramfs is used.]

- cmdline.txt: add 'fbcon=map:10 fbcon=font:VGA8x8'
- add /etc/modules-load.d/fbtft.conf with 'fbtft_device'
- add /etc/modprobe.d/00-fbtft.conf with 'options fbtft_device name=adafruit28 rotate=90 gpios=dc:25'

[2] http://h65951.serverkompetenz.net/PeterSeiderer/upload/PiTFT_2_8_ct/Image9897.jpg

[Thomas:
  - Rename prompt of the Linux extension to "FB TFT drivers"
  - Remove the full name of the kernel config options in the help
    text. Giving their CONFIG_<foo> name is enough.
  - Remove the mention of CONFIG_SPI_BCM2708, since this makes the
    description RaspberryPi specific, while these drivers can work
    with any SPI controller.
  - Refactor the code in linux-ext-fbtft.mk to avoid duplication
    between the < 3.15 and >= 3.15 cases.
  - Make the fbtft package a promptless package, since there is no
    point in selecting only this package, without the kernel
    extension.
  - Change the license to GPLv2, since it's kernel code.]

d4b2b032a0 linux: fix recursively defined variable
When running 'make printvars', the output stops at the time we dump the
Linux related variables, with:

    linux/linux.mk:109: *** Recursive variable `LINUX_TARGET_NAME'
    references itself (eventually).  Stop.

And that's expected, since we have:

    109 LINUX_TARGET_NAME = $(LINUX_IMAGE_NAME)
    [...]
    112 ifeq ($(LINUX_IMAGE_NAME),)
    113 LINUX_IMAGE_NAME = $(LINUX_TARGET_NAME)
    114 endif

Even though they are defined in a way that ensures they are in fact not
recursively defined (the if-block ensures that), 'printvars' does dump
all our variables by evaluating all of them, which in that specific case
implies they are recursively defined.

Fix that by explicitly setting LINUX_IMAGE_NAME in each if-block.

f268f7131b .mk files: bulk aligment and whitespace cleanup of assignments
The Buildroot coding style defines one space around make assignments and
does not align the assignment symbols.

This patch does a bulk fix of offending packages. The package
infrastructures (or more in general assignments to calculated variable
names, like $(2)_FOO) are not touched.

Alignment of line continuation characters (\) is kept as-is.

The sed command used to do this replacement is:
find * -name "*.mk" | xargs sed -i \
    -e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*$#\1 \2#'
    -e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\]\+\)$#\1 \2 \3#'
    -e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\ \t]\+\s*\\\)\s*$#\1 \2 \3#'
    -e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\(\s*\\\)#\1 \2\3#'

Brief explanation of this command:
    ^\([A-Z0-9a-z_]\+\)     a regular variable at the beginning of the line
    \([?:+]\?=\)            any assignment character =, :=, ?=, +=
    \([^\\]\+\)             any string not containing a line continuation
    \([^\\ \t]\+\s*\\\)     string, optional whitespace, followed by a
                            line continuation character
    \(\s*\\\)               optional whitespace, followed by a line
                            continuation character

Hence, the first subexpression handles empty assignments, the second
handles regular assignments, the third handles regular assignments with
line continuation, and the fourth empty assignments with line
continuation.

This expression was tested on following test text: (initial tab not
included)

	FOO     = spaces before
	FOO     =   spaces before and after
	FOO	= tab before
	FOO	  = tab and spaces before
	FOO =	tab after
	FOO =	   tab and spaces after
	FOO =   	spaces and tab after
	FOO =    \
	FOO = bar \
	FOO = bar space    \
	FOO   =		   \
	GENIMAGE_DEPENDENCIES   = host-pkgconf libconfuse
	FOO     += spaces before
	FOO     ?=   spaces before and after
	FOO     :=
	FOO     =
	FOO	=
	FOO	  =
	FOO =
	   $(MAKE1) CROSS_COMPILE=$(TARGET_CROSS) -C
	AT91BOOTSTRAP3_DEFCONFIG = \
	AXEL_DISABLE_I18N=--i18n=0

After this bulk change, following manual fixups were done:
- fix line continuation alignment in cegui06 and spice (the sed
  expression leaves the number of whitespace between the value and line
  continuation character intact, but the whitespace before that could have
  changed, causing misalignment.
- qt5base was reverted, as this package uses extensive alignment which
  actually makes the code more readable.

Finally, the end result was manually reviewed.
