You don't need that much, just reapply Grants patch(mentioned early in the
debate)
that were reverted because it did not work for everyone, probably due to some
other strange relocation scheme. I too have run u-boot with full .fixup applied
and it works. U-boot gets bigger, but that is most likely due to the old reloc
code
is just nullified instead of removed.
