This does not make much sense to me.  We should not try to push any
possible functionality into U-Boot just because we can.

U-Boot is a boot loader, and should only contain necessary
functionality and things, that are impossible or difficult to solve
in other ways.


I would much rather see the opposite direction working (again):
being able to pass information from U-Boot to Linux kernel and
further into Linux user land in a standard way.

Best regards,
