The Xtensa architecture had been removed because it required special
handling and depended on additional directories and files that became
obsolete over time. This change is more aligned to other architectures.
[Thomas: rebased on top of the "arch: improve definition of gcc mtune,
mcpu, etc." patch].

As stated in commit 555c2585bf28c3ef71f6d2dcdd983d17a19892af, 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 the BR2_LINUX_KERNEL_UBOOT_IMAGE boolean to
factorize more code that will be shared in the next patches that
introduces other uImage-like targets.

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 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 aaed42d15643e0cb64c96fa400a6097a19d19ef4.

The help text of BR2_LINUX_KERNEL_DEFCONFIG is confusing: it seems to
point to the defconfigs in the buildroot tree. So explicitly refer to
the kernel tree in the help text.

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.

There already is a default kernel version, so it makes little sense to have
a default custom kernel version as well. This default breaks the 'make
savedefconfig' if we want to force a specific version.

The 'vmlinux' target in the linux build directory is a generic target. It may
not be directly bootable for all architectures, but for projects where a custom
bootloader is used, it can be of value.
Previously, this target was only available for mips architectures. This patch
removes this restriction.
