	During NAND_SPL boot, base address and different register are programmed default by corresponding NAND controllers(eLBC/IFC). These settings are sufficient enough for NAND SPL. Avoid updating these register.They will be programmed during NAND RAMBOOT. Signed-off-by: Prabhakar Kushwaha <prabhakar@freescale.com>
