[U-Boot] [PATCH] powerpc/p1022ds: Add support for NAND and NAND boot using SPL

Matthew McClintock
2013-02-14T21:35:13Z

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 using
SPL framework from 2011
