On Armada 388 booting from eMMC is different to SD-Card in two major ways:
- Environment location - Sectors scanned by Boot-ROM
This patchset first makes it possible to select offset 4096 for eMMC partition. Here U-Boot can be placed to avoid conflict conflict with MBR.
Secondly the bubt command is updated to use LBA-4096 for eMMC data partition only, keeping previous values for SD and boot0/1 unchanged
Finally 3 new defconfigs are added - one for each bootable eMMC partition, selecting correct offset, and environment partition.
