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.

aaef2cad85 linux.mk: enable options for ktap
Certain tracing related options are required to be able to build ktapvm.ko, enable those.

Enable CONFIG_FUNTCTION_TRACER as otherwise, CONFIG_EVENT_TRACING won't stick. (Some
tracer needs to be enabled for this).

[Peter: add a note to ktap Config.in explaining this is done]

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.

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.

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)
