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.

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 improves two things:
* It makes sure that the linux-menuconfig and al. commands can be
executed even if the user hasn't executed 'make' before. Until now,
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 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.

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.

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.
