The option BR2_LINUX_KERNEL_INSTALL_TARGET used to install the kernel in
/boot in the rootfs. The introduction of the device tree builds made it
possible to generate device tree blobs, and stored them in IMAGES_DIR
like the kernel, but didn't copy the dtb in /boot when _INSTALL_TARGET
was enabled.

Closes#5846
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
the download URL.
Fix this by stripping off the final slash from the _SITE in all packages that
have a custom tarball.

The $(wildcard ) doesn't work for LINUX_APPEND_DTB, because the .dtb
doesn't exist yet at that point.
Also factor the common part out.

.dtb files are now generated in arch/$ARCH/boot/dts instead of
arch/$ARCH/boot, so extend the LINUX_INSTALL_DTB rule to look there
as well.

Only qstrip once and add a KERNEL_DTBS helper variable to simplify the dtb
rules.

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
handling and depended on additional directories and files that became
obsolete over time. This change is more aligned to other architectures.

mcpu, etc." patch].

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 is way too specific to microblaze-only. Remove this support to

The help text of BR2_LINUX_KERNEL_DEFCONFIG is confusing: it seems to
