[Buildroot] [PATCH 0/2] Samsung XE303C12 aka Chromebook Snow

[Alex Suykov <alex.suykov@gmail.com>]

This short series adds board config for Chromebook Snow.

There are several ways to boot a custom kernel on the device,
the one used here is perhaps the easiest to implement.
However, it needs vboot-tools to sign the custom kernel.

The kernel is packed into u-boot flat image tree (FIT) together with
the DT blob. Long story short, this is the only way I can get it to boot
with the original bootloader. Using uImage with appended DT should be
possible as well, but for some reason it does not seem to work.

At first I tried to add FIT option to the Kernel binary format menu,
because it's not really Chromebook-specific, but it turned out to be
ugly and much more complex than doing it in a post-build script.

Most of this boot stuff is common for all Chromebooks, even x86 ones,
but not for Samsung devices other than Chromebooks. Because of this,
it's boards/chromebook/snow and not boards/samsung/xe303c12.
