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.

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.

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

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

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.

When a package A depends on config option B and toolchain option C, then
the comment that is given when C is not fulfilled should also depend on B.
For example:

depends on BR2_B
depends on BR2_LARGEFILE
depends on BR2_WCHAR
comment "A needs a toolchain w/ largefile, wchar"
depends on !BR2_LARGEFILE || !BR2_WCHAR
This comment should actually be:
comment "A needs a toolchain w/ largefile, wchar"
depends on BR2_B
depends on !BR2_LARGEFILE || !BR2_WCHAR
or if possible (typically when B is a package config option declared in that
same Config.in file):
if BR2_B
comment "A needs a toolchain w/ largefile, wchar"
depends on !BR2_LARGEFILE || !BR2_WCHAR
[other config options depending on B]
endif
Otherwise, the comment would be visible even though the other dependencies
are not met.
This patch adds such missing dependencies, and changes existing such
dependencies from
depends on BR2_BASE_DEP && !BR2_TOOLCHAIN_USES_GLIBC
to
depends on BR2_BASE_DEP
depends on !BR2_TOOLCHAIN_USES_GLIBC
so that (positive) base dependencies are separate from the (negative)
toolchain dependencies. This strategy makes it easier to write such comments
(because one can simply copy the base dependency from the actual package
config option), but also avoids complex and long boolean expressions.

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)

Newer kernels had a slight change in the random number API so the OCF
patchset requires a slight tweak to build and run properly.
Affected kernels are, per series:
>=3.0.41, >=3.2.29, >=3.4.9, >=3.5.2 and any newer version.
The fix is applied by detecting the API change rather than guessing the
kernel version.

The Xtensa architecture had been removed because it required special

As stated in commit 555c2585bf, the
Xtensa architecture has been introduced in 2009 and never changed
since its initial introduction. It requires some special handling that
is a bit annoying, and despite our call to the initial developers, and
the announcement of the deprecation of the architecture during the
2012.05, nothing has happened. Therefore, drop support for this
architecture.

This patch adds support for the ARM-only appended device tree
mechanism present in the kernel.
This option allows to add at the end of the kernel image the
device tree blob so that we can still boot device tree enabled
kernels with old bootloaders.
This patch also adds the needed logic to genereate such an image
when building zImages or uImages, also adding the necessary parts
to rebuild the uImage.

This patch introduces some support for device tree-enabled kernels.
It replaces the former BR2_LINUX_KERNEL_DTS_FILE option that was
microblaze-only, that was quite limited. This option was quite
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 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.

This modifies the definition of DOWNLOAD to receive two arguments:

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

The post extract hook point is not really correct as what RTAI and

The post patch hook point doesn't work, because RTAI and Xenomai
patches would be applied *after* all other patches, while it sounds
more logical to apply them first, and *then* allow the user to apply
some platform/board specific patches if needed.

[Fixes by Thomas, including comments from Arnout:
* Use AUTOTARGETS instead of GENTARGETS
* Use $(KERNEL_ARCH) instead of $(BR2_ARCH) as argument to the
prepare-kernel.sh script. This allows the arch name to be fixed
with the usual sed expressions and the quotes to be stripped.
* Add the --verbose option to prepare-kernel.sh. This allows to get
some clear error message when no Xenomai patch has been found for
the current kernel version.
* Improve the help texts as suggested by Arnout, and remove the
now useless README file.
* Add a BR2_PACKAGE_XENOMAI_SMP option, instead of poking inside the
kernel configuration to find out whether SMP is enabled or
not. This cannot work because: 1) the kernel might be built
outside of Buildroot and 2) if the kernel is built inside
Buildroot, it is built *after* Xenomai, so the kernel
configuration file is typically not yet present.
* Simplify the ARM subarchitecture selection as suggested by Arnout.
* Remove the documentation and development files according to
Buildroot standards (using BR2_HAVE_DOCUMENTATION and
BR2_HAVE_DEVFILES).
* Simplify the /etc/ld.so.conf modification logic.

As the kernel and bootloaders do not use the normal BR2_PACKAGE_*
Kconfig options, their target name was not automatically added to the
global TARGETS variable. Each bootloader .mk and the linux.mk had to
add their own target manually to TARGETS, and the package
infrastructure was making tests on non-existing Kconfig variables.
This commit improves the package infrastructure so that it looks at
BR2_PACKAGE_<pkg> for packages, BR2_TARGET_<pkg> for bootloaders and
at the special BR2_LINUX_KERNEL for the linux package.
This allows to simplify a little bit the bootloaders and linux .mk
files.
