I was under the impression that this was a developer discussion about
what it would take to get this working, not an end user support forum.

It was over a year ago that I made that request internally. And still
the answer is "I need this now now now!".

NACK any non-SPD NAND boot for a board that otherwise uses SPD,
particularly if it has socketed RAM. It's not as if we don't know how
to make this work.

Wolfgang will also probably object to adding another board to the old
nand_spl infrastrucutre.
