mtd: nand: Add max_bb_per_die and blocks_per_die fields to nand_chip (ceb374eb) · Commits · 戴 / test

The fields max_bb_per_die and blocks_per_die are useful determining the number of bad blocks a MTD needs to allocate. How they are set will depend on if the chip is ONFI, JEDEC or a full-id entry in the nand_ids table. Signed-off-by:
