From ee782e877d8c50f3ed775aee8934565699a5fc99 Mon Sep 17 00:00:00 2001
From: mokopatches <mokopatches@openmoko.org>
Date: Wed, 16 Jul 2008 14:44:10 +0100
Subject: [PATCH] s3c2410-bbt.patch
[PATCH] Add Kconfig option to enable NAND bad-block-table support for s3c2410
This patch adds a new CONFIG_MTD_NAND_S3C2410_BBT which, if enabled,
asks the mtd NAND core to use a bad-block table.
Signed-off-by: Harald Welte <laforge@openmoko.org>
