From ceb374eb06848212e47fb884964a3ae5e79615b5 Mon Sep 17 00:00:00 2001 From: Zach Brown Date: Tue, 10 Jan 2017 13:30:19 -0600 Subject: [PATCH] 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.
