Did you bisect to that patch?

The proper fix would be to get away from OF_EMBED which is not allowed
in production boards. Can you post the full console log so I can see
what happens before the error?

The commit does not look correct to me. This is nothing to do with the
horrible NEEDS_MANUAL_RELOC which is only needed on m68k I think now.
It is because we have moved the executable containing the DT. The DT
in the old position may be overwritten by loading something.
