We've had issues in the past with boards that did not detect NAND. Can
you look up the u-boot archives for this?

How did you come to this conclusion? NULL pointers are constants and
thus are *not* relocated.

I suggest visually running through all (board or cpu-specific) code that
runs as part of execution board_init_f() and checking that no global is
ever used -- BSS or initialized.
