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.

b1f0212af6 linux: properly install all images in the initramfs case
The target "$(LINUX_DIR)/.stamp_initramfs_rebuilt" uses its own
'cp' command, instead of LINUX_INSTALL_IMAGE/LINUX_INSTALL_IMAGES_CMDS
provided by (or updated with) commit 055e6162bb ("linux: don't build
appended DTB image in place and support multiple images") and thus is
not operating properly when APPENDED_DTB is used.

Indeed, it copies a single image, and does not copy the one with the DTB
appended.

This patch replaces the 'cp' command with LINUX_INSTALL_IMAGE which
handles APPENDED_DTB.

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).

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
   BR2_LINUX_KERNEL_INTREE_DTS_NAME="armada-xp-matrix armada-xp-gp armada-370-mirabox"

   Contents of output/images:

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

In all configurations, the contents of output/target/boot/ was the
same if BR2_LINUX_KERNEL_INSTALL_TARGET=y.

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.
