I don't see why the ifdef is needed -- just don't put it inside (or
before) the other ifdef.

The messages are expected on the first boot -- but it should then create
the bad block table.
You'll have to debug to find out why it's hanging. If you don't set
NAND_USE_FLASH_BBT, does ordinary nand read/write from the u-boot prompt
work?
