ARM: at91: at91sam9n12ek: save the environment to a fat file in MMC card
Insteading in mmc's raw sectors, this patch will save the environment
in a fat file (uboot.env) in mmc card's first FAT patition by default.
If you want to save in mmc's raw sectors, you only need to define
CONFIG_ENV_IS_IN_MMC.
