ramips: disable badblock shifting for MT7621 NAND
The MediaTek MT7621 NAND driver currently intransparently shifts NAND pages when a block is marked as bad. Because of this, offsets for e.g. caldata and MAC-addresses seem to be off. This is, howeer, not a task for the mtd NAND driver, as the flash translation layer is tasked with this. This patch disables this badblock shifting. This fix was originally proposed by Jo-Philipp Wich at https://bugs.openwrt.org/index.php?do=details&task_id=1926 Fixes FS#1926 ("MTD partition offset not correctly mapped when bad eraseblocks present") Signed-off-by: David Bauer <mail@david-bauer.net>
