From 66372fe2ab11cdeb0e841ad9eb6ba79769db4909 Mon Sep 17 00:00:00 2001 From: Mingkai Hu Date: Thu, 18 Jun 2009 18:23:27 +0800 Subject: fsl_elbc_nand: redirect the pointer of bbt pattern to RAM The bbt descriptors contains the pointer to the bbt pattern which are statically initialized memory struct. When relocated to RAM, these pointers will continue point to NOR flash(or L2 SRAM, or other boot device). If the contents of NOR flash changed or L2 SRAM disabled, it'll hang the system.
