From 34da5f5f3bf5c0df1bd5528a98e07bd5a224e9d4 Mon Sep 17 00:00:00 2001 From: Zach Brown Date: Tue, 10 Jan 2017 13:30:21 -0600 Subject: [PATCH] mtd: nand: set max_bb_per_die and blocks_per_die for ONFI compliant chips ONFI compliant chips contain the values for the max_bb_per_die and blocks_per_die fields in the parameter page. When the ONFI paged is retrieved/parsed the chip's fields are set by the corresponding fields in the param page.
