From: Haiying Wang Haiying.Wang@freescale.com
This patch defines 1M TLB&LAW size for NAND on MPC8572DS, assigns 0xffa00000 for CONFIG_SYS_NAND_BASE and adds other NAND supports in config file.
It also moves environment(CONFIG_ENV_ADDR) outside of u-boot image, to make room for the increased code size with NAND enabled.
