mtd: spinand: core: Properly fill the OOB area.
The comment in spinand_write_to_cache_op() says that spinand_ondie_ecc_prepare_io_req() should 0xff fill the OOB area but it doesn't. This causes the OOB area to get filled with zeros and anytime the first page in a block the bad block marker is cleared and it becomes a bad block on the next boot. This was observed on Longsys FORSEE branded parts and might be specific to these parts.
