Update the code and the configs for eMMC boot and userdata
partitions acces
- FASTBOOT_MMC_BOOT_SUPPORT: boot partition 1 and 2 (erase/write)
- FASTBOOT_MMC_BOOT1_NAME: boot partition 1, default name="mmc0boot0"
- FASTBOOT_MMC_BOOT2_NAME: boot partition 2, default name="mmc0boot1"
This patch also removes the unnecessary dependency with
ARCH_MEDIATEK and EFI_PARTITION.
