From 5954c47c2194abcdeeae5f752e64b7c75770dbd3 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Sat, 16 Oct 2010 18:26:59 -0400 Subject: [PATCH] mtd: Blackfin NFC: fix badblock location with BootROM OOB The bbt structure isn't actually used, just the badblockpos. This lets the driver correctly handle badblocks with the different OOB layout with certain sized flashes. Previously, the blocks would all be reported as bad and be completely unusable.
