ba4ad9d27c deprecated handling: introduce BR2_DEPRECATED_SINCE_xxxx_xx
In order to keep better track of when a feature got deprecated, and hence
when it can be removed, a new set of symbols BR2_DEPRECATED_SINCE_xxxx_xx is
introduced. These symbols are automatically selected when BR2_DEPRECATED is
selected, and thus are transparent to the user.
A deprecated feature will no longer depend on BR2_DEPRECATED directly, but
rather on the appropriate BR2_DEPRECATED_SINCE_xxxx_xx. If that symbol does
not yet exist, it has to be created in Config.in.
When removing a deprecated feature, one should also check whether this was
the last feature using the BR2_DEPRECATED_SINCE_xxxx_xx symbol, in which
case the latter can be removed from Config.in.

A followup patch will make sure the overview is added to the list of
deprecated features in the manual, so that a buildroot core developer can
easily determine which features to remove in a given development cycle.

9e680d0ada fs/ext2: fix generation of ext4 filesystems
cset 7a58a4e (e2fsprogs: bump to version 1.42.9) broke the generation
of ext4 filesystems.

This is because, in ext4, some metadata are dependent on the UUID.
If changing the UUID of an ext4 filesystem, tune2fs now exits with
exit-code 1, and prints a message to run fsck, to avoid trashing the
filesystem.

This condition is of utmost importance on a mounted filesysten (which
is not our case) to avoid corruption (yes, it is possible to change
the UUID of a mounted filesystem).

But the error is not valid for us, since we are working on an unmonted
filesystem image in the first place.

Since we change the UUID after we convert the filesystem (to ext4),
tune2fs just bails out.

We can not just ignore the exit code of tune2fs, since we still want
to catch any other failure.

It turns out that, changing the UUID before converting the filesystem
is just the way to go.

Fixes #6752.

b49c231cab fs/iso9660: put the Buildroot boot entry first in Grub menu.lst
The ISO9660-specific Grub menu.lst contains two entries: one entry to
chainload the bootloader available in the first hard drive, and
another entry to boot the Buildroot system.

However, it defaults to booting the first entry, i.e chainloading
what's on the first hard drive. For a Buildroot generated system, this
is quite odd: we're not even booting the system built by Buildroot.

So, switch the two entries, and put the Buildroot boot entry first.

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.

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)

d8286a993a package/genext2fs: add host variant
genext2fs is built only if the user selected an ext2 root filesystem.

However, some use-cases can't live with the full target/ dir on the
root filesystem, and requires separate partitions (eg. for /usr).
In this case, the user would not select an ext2 root fs in the
Buildrooot menu, and would only generate a tarball of the rootfs.
This tarball would then be used from a post-image script to build
the actual required FSes.

But then, genext2fs is not built, since the ext2 root FS was not
selected.

As for the other filesystem generators, provide a host variant of
genext2fs (genext2fs is already host-package aware, so only needs
adding a Kconfig entry).

60474dcec6 fs/ext2: further fix to the UUID
Turned out that setting a nil-UUID is no better than clearing it.

What currently happens is as follows:
  - first, genext2fs does not generate a UUID
  - then we tune2fs to upgrade the filesystem
  - then we run fsck, which generates a random UUID
  - then we re-run tune2fs to set a nil-UUID

So, on the target, if the file system is improperly unmounted (eg.
with a power failure), on next boot, fsck may be run, and a new
random UUID will be generated.

*However*, fsck improperly updates the filesystem when it adds the
UUID, and there are a few group descriptor checksum errors.

Those errors will go undetected until the next fsck, which will then
block for user input (bad on embedded systems, bad).

Fix that by systematically generating a random UUID _before_ we call
to fsck.

A random UUID is not so bad, after all, since there are already so
many sources of unpredictability in the filesystem: files date and
ordering, files content (date, paths...) which renders a fixed UUID
unneeded.

And it is still possible to set the UUID in a post-image script if
needed, anyway.

69036c20f1 fs/ext2: add ability to build ext3/4 too
Use the host-e2fsprogs to tune2fs the generated rootfs.ext2 image,
and upgrade it to either one of ext2, ext3 or ext4.

Since calling tune2fs may require running e2fsck (tune2fs will warn
to do so when certain FS options are changed), we systematically call
e2fsck. This makes the code path simpler, and as a side-effect checks
that genext2fs did not generate garbage.

In turn, e2fsck will unconditionally add a UUID to the filesystem,
which is bad for reproducibility, so we call tune2fs again to remove
the UUID. This does not require checking the filesystem.

To ensure compatibility of Buildroot's .config, leave ext2 as the
default. Boards' .config can override this at will.

402d1476f7 fs/common.mk: Strip extra whitespace when device table is empty
Since ROOTFS_DEVICE_TABLES is a concatenation of two strings separated by
spaces, there will always be a space in it, which means it's never empty.
Therefore, when testing for empty, the condition never evaluate to false.

The following change fixes this problem; it runs qstrip on the overall
combination of the variables, causing the space to be removed if it's the
only thing left.

847895d295 fs/common.mk: delay evaluation of variables
This makes things easier to understand and more consistent with the pkg-infra.
For example, it removes the need for '$$@' in the CMD variables of fs/*/*.mk.

It also makes it possible to update the variables later, e.g. in the package
override file.

It also makes sure that the date will be recorded correctly in Yann E. Morin's
patch that logs the MESSAGE macros to a file.

The fs/*/*.mk must be updated as well because the '$@' shouldn't be quoted
anymore in the CMD variables or the hooks.

The $(eval ...) for the dependencies is redundant, because the $(ROOTFS_TARGET)
variable is already eval'd. Note that it is only redundant if the evaluation of
the uses of the variable is also delayed.

e1ebae700a fs/common: Create initial console device
A /dev/console node must be present in rootfs when the Linux kernel
boots otherwise the kernel will print the following warning:
"Warning: unable to open an initial console"

This is because when we use an initramfs the /dev directory is not
populated at this point. This can cause problems when a program
(e.g ldso with early debugging enabled) opens a standard file
descriptor for read/write before these descriptors are actually
created by the init process later on.

9226a9907c Warn the user about the usage of output/target as the root filesystem
A very common mistake done by our users is that they use
output/target/ directory as their root filesystem. Even though this is
loudly documented in our Buildroot manual, people don't read
documentation, so it is not sufficient.

This patch adds a text file named
output/target/THIS_IS_NOT_YOUR_ROOT_FILESYSTEM which explains why
output/target isn't appropriate to use as the root filesystem. The
process is:

 * At the beginning of the build, right after the skeleton has been
   copied, support/misc/target-dir-warning.txt is copied to
   output/target/THIS_IS_NOT_YOUR_ROOT_FILESYSTEM

 * In the filesystem images creation code, this file is removed before
   launching fakeroot, and restored right after that, so that this
   file is not present in the generated root filesystem images.

Note that the file has not been added to the default skeleton for two
reasons:

 * It would have annoying to have in our source tree a file named in
   capital letters inside system/skeleton/

 * The proposed way works even if the user uses a custom skeleton.

ff3391323a iso9660 fs: use cpio initrd instead of ext2
The ext2 initrd is pretty broken, because it requires an additional
root=/dev/ram0 command line parameter, and a /init to mount
devtmps that isn't there in out ext2 rootfs.  So just use a cpio
instead.

Note that there is no check if the kernel supports initramfs or the
selected compression method.

Also removed a bit of dead code in iso9660.mk.

7e61918f9d cpio/initramfs: clarify their use in the help text
Recent mails on the list show that it is not very clear how to create
an initial RAM fs with buildroot.  So make this more explicit in the
cpio and initramfs help texts.  Hopefully this will reduce the /init
debugging we have to do.
