ENGR00315894-12 i.mx6:sabreauto/sabresd: Change the MMC settings
1. Change CONFIG_MMCROOT to mmcblk0p2.
Kernel always sets the first availiable MMC/SD device to mmcblk0
2. Make the MMC ENV DEV/PART independent of ENV_IS_IN_MMC
3. Add the CONFIG_SYS_MMC_ENV_PART to 0 (user area) for u-boot env saving.
CONFIG_SYS_MMC_ENV_PART: was used to tell the u-boot which
emmc (boot)partition to be used for the env_mmc.Usually, the
emmc card will have 2 boot partitions, boot1 and boot2.
0: means user area
1: means boot partition 1
2: means boot partition 2
If user want to use the boot partition to store the u-boot env, please
change the CONFIG_SYS_MMC_ENV_PART to which boot partition you want.
4. Add the CONFIG_SYS_MMC_IMG_LOAD_PART for the partition number where the kernel
and DTB will load from. At default, it is the first partition in VFAT format.
