From: 张忠山 <zzs0213@xxxxxxxxx>
when CONFIG_NAND_BBT not set, chip->scan_bbt is NULL and
NAND_SKIP_BBTSCAN not set. So barebox crashed, this is the message
......
nand: ONFI param page 0 valid
nand: ONFI flash detected

may be the best solution is set NAND_SKIP_BBTSCAN somewhere when
CONFIG_NAND_BBT not selected, but I don't known where is the best
position.
