mtd: Blackfin NFC: fix badblock location with BootROM OOB
The bbt structure isn't actually used, just the badblockpos. This lets the driver correctly handle badblocks with the different OOB layout with certain sized flashes. Previously, the blocks would all be reported as bad and be completely unusable. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
