[U-Boot] [PATCH 2/2] powerpc/p1022ds: Add support for NAND and NAND boot
Timur Tabi
timur at freescale.com
Fri May 18 18:04:18 CEST 2012
From: Matthew McClintock <msm at freescale.com>
Add defines needed to access NAND, remove second flash bank that is
actually connected to NAND.
Add nand booting support for P1022DS with hardcoded DDR config
