9bd541d3b2 linux: simplify adding new extensions
Curently, all three linux extensions follow the same layout:
  - test if the extension is enabled
  - 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

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.

[Thomas: adjust comment in the code according to Yann comments.]

541d9937d4 linux/linux.mk: custom dts path - build dtb only from *.dts files
When building device tree blobs from custom *.dts files, buildroot
initializes KERNEL_DTS_NAME variable from all given file names.
This causes that user can't provide one *.dts file and some other
*.dtsi files as dependencies.

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.

[Thomas: add comment into the code to explain why we are filtering
.dts files only.]

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.]

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.

62bbfbaa63 pkg-utils: kconfig helpers: use single iso double quoting
The echo statements in the kconfig helpers are currently using double
quotes. For KCONFIG_SET_OPT this is problematic when the value argument
itself contains a double quote (a string value). In this case, the statement
    echo "$(1)=$(2)" >> $(3)
would become:
    echo "FOO="string value"" >> /some/path/.config
resulting in the string
    FOO=string value
in the config file, rather than the properly quoted
    FOO="string value"

The linux package worked around this by escaping the quote characters, but
a prettier solution is to use single quoting in the helpers (or
alternatively use no quoting at all).
A side effect of this change is that a $variable in the key or value would
no longer be interpreted by the shell, removing any unexpected behavior.

This change is only really necessary for KCONFIG_SET_OPT, but for symmetry
reasons the other helpers are updated too.

SMACK. The proper kernel options are also set.

[Thomas:
- fixed license to be LGPLv2.1 instead of LGPLv2.1+. Even though the
  debian/copyright file has the "or later" indication, none of the .c
  source files carry it, so I suppose LGPLv2.1 is more correct.
- added !BR2_PREFER_STATIC_LIB dependency.

ca80782f45 linux: only depend on host-lzop if needed
There is no reason to always depend on host-lzop, even when the kernel
compression is not LZO.

Since LZO is not the default compression option in the kernel (and there
is not sign that will change in the foreseeable future), it will always
appear in a config file, whether it is a complete config file or it is
only a defconfig.

So, only depend on host-lzop if the LZO compression is enabled in the
kernel config file (either the defconfig or the custom config file).
This includes:
  - kernel compression itself
  - initrd compression
  - initramfs compression

2c66e4429d systemd: bump to v207
This patch bumps systemd to v207 but also declares it as a provider for the
udev virtual package.

Starting with systemd 183, udev has been merged into
systemd. The udev daemon is now installed as /lib/systemd/systemd-udevd.
This means that /dev management using udev is only available if systemd
is chosen as init system.

When configuring systemd, the following options are available:

- activation of systemd-journal-gatewayd, to access the journal via
  HTTP.
- activation of extra features like journal compression and sealing.

Support for uClibc has also been removed because:

- upstream has no interest in supporting uClibc.
- using a shrinked libc brings no advantage, given the size of all the
  programs included in Systemd. So using glibc does not matter.

ed23c92b62 linux: enable initrd/initramfs support when cpio rootfs is chosen
When one enables the generation of a cpio archive of the root
filesystem, the most likely usage is as an initramfs for the
kernel. This commit ensures that the kernel has initramfs support when
the rootfs cpio image format is chosen.

This will for example ensure that if the user selects the ISO9660
filesystem format (which uses a cpio initramfs), the kernel will have
proper support to load and use the initramfs.

It is worth mentionning that when BR2_TARGET_ROOTFS_INITRAMFS is
enabled, then BR2_TARGET_ROOTFS_CPIO is always enabled. That's why we
move the enabling of CONFIG_BLK_DEV_INITRD from the initramfs case to
the cpio case.

391c82efa1 linux: Do not force GZIP initramfs compression
Initramfs compression does not make much sense for the architectures
that support compressed kernel images because in this case the data
would be compressed twice. This will eventually result in a bigger
kernel image and time overhead when uncompressing it.
The only reason to use compressed initramfs is to reduce memory
usage when the kernel prepares rootfs, and both the unpacked
filesystem and initramfs.cpio are present in the memory.

Buildroot attempts to force GZIP compression for initramfs,
however it doesn't always work because initramfs compression mode
depends on RAM disk compression supported by the kernel.
Thus, CONFIG_INITRAMFS_COMPRESSION_GZIP depends on CONFIG_RD_GZIP.
If CONFIG_RD_GZIP is not set, setting GZIP initramfs compression
will have no effect.

Besides, the kernel also supports other compression methods,
like BZIP2, LZMA, XZ and LZO. Forcing the good old GZIP does not
really make much sense any more.

This removes initramfs compression settings from Buildroot,
so that the default value preset in the kernel config is used,
which is CONFIG_INITRAMFS_COMPRESSION_NONE.

If initramfs compression is still needed, it can be set
in the kernel config (using make linux-menuconfig)

It replaces the former BR2_LINUX_KERNEL_DTS_FILE option that was

limited, first obviously because it was restricted to microblaze,
but also because it targetted only external device tree source files,
and allowed only to build simpleImages using the custom image name
mechanism.

This patch adds a much more generic one, that can work on basically
every architecture that supports device tree. It allows to build
both device tree source file that comes with the kernel source or to
set the path to the device tree file to use so that one can use a
custom device tree.

This is way too specific to microblaze-only. Remove this support to
introduce a more generic way to do support device tree kernels.

This reverts commit aaed42d156.

Also remove the redundant $(call ...).

This is a purely mechanical change, performed with

707d44d0a2 linux: install dtc (device tree compiler) as host tool if selected
Having dtc as a host tool can be useful for users that have a custom
boot scenario where the device tree is not embedded in the kernel.

f18c51657f linux: improve the 'make linux-*' special commands
This patch improves two things:

 * It makes sure that the linux-menuconfig and al. commands can be
   executed even if the user hasn't executed 'make' before. Until now,
   the commands were depending on the .configured stamp, which is not
   sufficient since the linux package has been converted to the
   GENTARGETS infrastructure. Instead, depend on the linux-configure
   phony target.

 * It makes sure that those commands are not available when the Linux
   package is not selected, just like we do for Barebox.

aaed42d156 Microblaze: build kernel with device tree
This patch adds the options needed to build the SimpleImage containing
the device tree structure needed for the Microblaze architecture.

Handling Device Tree and SimpleImage will be handled in a general way
in the future.

I provide this patch to be able to build the system in the meantime.

0a4856ce27 DOWNLOAD: change $1=DIRECTORY_URL, $2=FILE_NAME to $1=FULL_FILE_URL, $2=FILE_NAME
This modifies the definition of DOWNLOAD to receive two arguments:
the first one is the full URL of the file to download, whereas the second
(and optional) is the name the file will have once downloaded.

Same thing with the SOURCE_CHECK_WGET and SCP functions.

All calls to these functions have been changed to the shortest form of
the new API, except for toolchains acquisition. Since there is quite a
number of different toolchains this call to DOWNLOAD is better set to the
generic one.

0900c12556 linux: add linux-update-config and linux-update-defconfig targets
In analogy to build targets uclibc-update and busybox-update, add
extra targets to copy the current configuration to the custom
configuration file set in buildroot. These targets facilitate the
work of developers adding support for a specific board.

linux-update-config copies .config directly.
linux-update-defconfig first creates a defconfig and copies that.
