From 9db41f9edcb87ae050fcb171c44be7f212728d54 Mon Sep 17 00:00:00 2001 From: Michel Pollet Date: Wed, 13 May 2009 16:54:14 +0100 Subject: [MTD] [NAND] S3C2410: Allow the machine code to get the BBT table from NAND Added a flag to allow the machine code to tell the NAND subsystem that it should try to pickup a BBT from the flash, and also skip the NAND full scan at startup.
