The KERNEL_CUSTOM_TREE option is not in mainline Buildroot. And as per
my answer to the previous patch, I'd very much prefer a more generic
solution than a solution specific to the Linux kernel build process.

I have a similar comment here: I agree that we must have GIT and SVN
support for the Linux build process, but we should also have it for all
the bootloaders (see the recent patch to introduce X-Loader).
Therefore, instead of solving it in a Linux-specific way, I'd prefer if
we could have a generic infrastructure (in the spirit of the package
infrastructure) that would satisfy the need of bootloaders and Linux
kernel in terms of build process.

Yes, it's a lot more work than just making the change on the Linux
kernel build process only, but on the long term, it's much more
interesting.

Regards,

Thomas
