[PATCH v3 3/5] mtd: nand: Add bb_per_lun and blocks_per_lun fields to nand_chip

From: Zach Brown
Date: Fri Oct 28 2016 - 16:28:51 EST


The fields bb_per_lun and blocks_per_lun 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 fuill-id entry in the nand_ids
table.
