Currently the MMC environment driver supports storing redundant environment only in one eMMC partition at different offsets. This is sub-optimal, since if this one boot partition is erased, both copies of environment are lost. Since the eMMC has two boot partitions, add support for storing one copy of environment in each of the two boot partitions. To enable this functionality, select CONFIG_SYS_REDUNDAND_ENVIRONMENT to indicate redundant environment should be used. Set CONFIG_SYS_MMC_ENV_PART to 1 to indicate environment should be stored in eMMC boot partition. Set CONFIG_ENV_OFFSET equal to CONFIG_ENV_OFFSET_REDUND, and both to the offset from start of eMMC boot partition where the environment should be located.
