[U-Boot] Question about relocation

Ori, simply, end-to-beginning when moving up. Or always
end-to-beginning since we are expected to always move up (upper than
the target address it can't run).

It is safer, but not safe. Also, it's difficult to accomplish bcause
copying and fixing addresses is done ina single run, so the relocation
tables are read from the old area. Possibly relocatng first and
copying then.

Or, easier: if we are already high enough to overlap, don't relocate
at all.  If it's acceptable, I'll patch for taht.
