I understand that some ARM patches would be stored in some branch
(say rmobile/master) of the u-boot-sh repo and pull-requested to me
from there.

What I still don't understand is *why* this should be done. Before they
get on this branch, the patches would still have to go through the
mailing list for review, just like the ARM patches that end up applied
to u-boot-arm/master, except they'd have to do through an intermediate
branch. If there are benefits in this, someone will have to lay them
out for me, because right now I don't see them.

Amicalement,
