4ff3aa2288 Revert "linux: fix the KCONFIG_GET_OPT calls to be inside a BR2_LINUX_KERNEL test"
This reverts commit 4ad1ea59a5. The
whole host-lzop optional dependency logic cannot work, since the
configuration file will only be known after the kernel sources are
extracted, if an internal kernel defconfig is used, which is quite
common.

4ad1ea59a5 linux: fix the KCONFIG_GET_OPT calls to be inside a BR2_LINUX_KERNEL test
The KCONFIG_GET_OPT calls added by
ca80782f45 ('linux: only depend on
host-lzop if needed') are made even if the kernel package is not
selected. This hangs the linux.mk parsing as they try to read from a
file that doesn't exist.

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.

This patch converts udev to a virtual package. For the moment, there is only

Packages meant to provide udev-like features must select the symbol
BR2_PACKAGE_HAS_UDEV.

Packages depending on BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_UDEV or
BR2_PACKAGE_UDEV have been converted to use the new symbol.

937a95449e eudev: new package
eudev is a userspace device management daemon. It is a standalone
version, independent from systemd. It is a fork maintained by Gentoo.

Features:

 - No extra configuration options are available: Gudev is build if
   libglib2 is selected.
 - No dependency on hwdata as the package uses its own hardware
   database (as does systemd).

eudev 1.3 is in sync with systemd v207.

05e2e35715 linux: don't automatically set uevent_helper with mdev /dev management
When mdev /dev management is chosen in the buildroot configuration, the
Linux configuration is updated automatically to set option
CONFIG_UEVENT_HELPER_PATH to "/sbin/mdev". However, the help text of this
option explicitly recommends not setting this option due to large
performance impact during boot (experienced first hand by the reporter ánd
author).

The mdev startup script S10mdev already sets the helper during userspace
boot, which will make sure mdev is working correctly.

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.

be084204eb Config.in files: add missing dependencies to toolchain option comments
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:

config BR2_PACKAGE_A
	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.

build process. It makes sense to mention that in the help text of this
option.

1ac04c321f Fix building initramfs kernel with appended dtb
The target for building the kernel with a cpio initramfs is not
calling the append dtb commands, creating a final kernel image
without an appended dtb. Instead it needs to call kernel make on
the intermediate target, then call the append dtb commands
to produce the final image as the primary kernel build target
does.

Fixes bug #5516 - appended device tree blobs on uImage fails

Before version 3.7 of the kernel, building the zImage and then the
uImage will rewrite the zImage in the process, removing the device tree
we just appended.

Use mkimage to append the device tree to the uImage and rebuild the
headers directly.

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)

The $(dir ...) function leaves a slash at the end, so that the LINUX_SITE
variable for a custom tarball ends in a slash. The DOWNLOAD macro adds
another slash between SITE and SOURCE, which results in a double slash in

Fix this by stripping off the final slash from the _SITE in all packages that

Affected kernels are, per series:

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.

978928e4ac Add support for appended device tree blobs for arm
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.

69fc497df0 Rework support for the device tree
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

   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:
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.

be27a7933f rtai, xenomai: use the pre patch hook point
The post extract hook point is not really correct as what RTAI and
Xenomai extensions are doing is patching the kernel.

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.

956d4ab0f5 Add xenomai real-time Framework to buildroot
[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.

f45f775b4f linux: add support for 3.x and -rc versions
The assumption that all kernels are in
http://www.kernel.org/pub/linux/kernel/v2.6/ is no longer true:
versions 3.x are in separate directories.

We now compute the directory name from the major and minor versions of
the version provided by the user. This assumes that the 3.1 version
will be in a /v3.1/ directory, which we don't know yet because the 3.1
cycle hasn't started yet.

At the same time, we add support for the official -rcX versions.

Patch tested by compiling 3.0-rc6, which Buildroot has successfully
downloaded and built.

b0d446dee4 Improve TARGETS handling for bootloaders and kernel
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.

 - static method uses device table as before
 - devtmpfs method enables this feature in kernel
 - mdev method adds mdev starting script to the file system
    and selects mdev itself for installation
 - udev method selects udev for installation

All dynamic methods are based on devtmpfs, so one doesn't need to care

e88704dfba linux: don't force IPv6 configuration in kernel
As per the discussion at
http://lists.busybox.net/pipermail/buildroot/2010-December/040030.html,
remove the bits that forced the IPv6 configuration in the kernel
depending on the toolchain ability to support (or not) IPv6. You may
have a toolchain with IPv6 support but still don't want to have IPv6
in your kernel.

The only parameters we adjust in the kernel configuration are:

 * ARM EABI, since we got a lot of bug reports regarding misconfigured
   kernel compared to the ABI used by userspace applications.

 * initramfs, since its contents are generated by Buildroot itself

process was failing. It was because he just forgot to set the path of
the configuration file.

Of course, it doesn't catch all mistakes (like pointing to a
non-existing defconfig or to a non-existing configuration file), but
it at least catches basic mistakes.

f507921d39 linux: add support for initramfs
In Buildroot, the kernel is built and installed *before* the root
filesystems are built. This allows the root filesystem to correctly
contain the kernel modules that have been installed.

However, in the initramfs case, the root filesystem is part of the
kernel. Therefore, the kernel should be built *after* the root
filesystem (which, in the initramfs case simply builds a text file
listing all files/directories/devices/symlinks that should be part of
the initramfs). However, this isn't possible as the initramfs text
file would lack all kernel modules.

So, the solution choosen here is to keep the normal order: kernel is
built before the root filesystem is generated, and to add a little
quirk to retrigger a kernel compilation after the root filesystem
generation.

To do so, we add a ROOTFS_$(FSTYPE)_POST_TARGETS variable to the
fs/common.mk infrastructure. This allows individual filesystems to set
a target name that we should depend on *after* generating the root
filesystem itself (contrary to normal ROOTFS_$(FSTYPE)_DEPENDENCIES,
on which we depend *before* generating the root filesystem).

The initramfs code in fs/initramfs/initramfs.mk uses this to add a
dependency on 'linux26-rebuild-with-initramfs'.

In linux/linux.mk, we do various things :

 * If BR2_TARGET_ROOTFS_INITRAMFS is enabled (i.e if initramfs is
   enabled as a root filesystem type), then we create an empty
   rootfs.initramfs file (remember that at this point, the root
   filesystem hasn't been generated) and we adjust the kernel
   configuration to include an initramfs. Of course, in the initial
   kernel build, this initramfs will be empty.

 * In the linux26-rebuild-with-initramfs target, we retrigger a
   compilation of the kernel image, after removing the initramfs in
   the kernel sources to make sure it gets properly rebuilt (we've
   experienced cases were modifying the rootfs.initramfs file wouldn't
   retrigger the generation of the initramfs at the kernel level).

This is fairly quirky, but initramfs really is a special case, so in
one way or another, we need a little quirk to solve its specialness.

4944e8c883 linux: add support for linux26-{menuconfig,xconfig,gconfig} targets
These targets allow the user to customize the configuration of the
Linux kernel. After changing the kernel configuration, the next time
the user runs "make", the kernel is rebuilt to take into account the
new configuration (not rebuilt from scratch).

100c09a53b linux: adjust kernel config according to the Buildroot configuration
We only adjust the configuration or ARM EABI and IPv6. The (more
complicated) initramfs case is handled in a separate commit. The user
is expected to take care of all other configuration details (like
having Netfilter enabled to make iptables work, etc.)

487e21cff6 New, simpler, infrastructure for building the Linux kernel
This patch introduces a single, simple, infrastructure to build the
Linux kernel. The configuration is limited to :

 * Kernel version: a fixed recent stable version, same as kernel
   headers version (for internal toolchains only), custom stable
   version, or custom tarball URL

 * Kernel patch: either a local file, directory or an URL

 * Kernel configuration: either the name of a defconfig or the
   location of a custom configuration file

 * Kernel image: either uImage, bzImage, zImage or vmlinux.
