From: Adriana Kobylak <anoo@us.ibm.com>

The ast2600 openbmc will favor eMMC over NOR. Moving the
environment to eMMC and configuring it as a redundant
environment. The location is the first partition of the
User Data area (mmcblk0p1), which is at offset 0x5000
because of the GPT header plus it's 4k-aligned.

CONFIG_SYS_MMC_ENV_DEV 0 /* User data mmcblk0 */
CONFIG_ENV_OFFSET 0x5000 /* Offset from beginning of dev */
CONFIG_ENV_OFFSET_REDUND 0x6000 /* ENV_OFFSET + 0x1000 */
