From: Zach Brown Date: Tue, 10 Jan 2017 19:30:19 +0000 (-0600) Subject: mtd: nand: Add max_bb_per_die and blocks_per_die fields to nand_chip X-Git-Tag: v4.14-rc1~1520^2~13 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ceb374eb06848212e47fb884964a3ae5e79615b5;p=platform%2Fkernel%2Flinux-rpi.git mtd: nand: Add max_bb_per_die and blocks_per_die fields to nand_chip 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.
