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
Changes since v1:
- New defconfigs for environment location are skipped in this version, pending further research if it can be auto-detected.
- invert logic of if statement allowing it to compile both with, and without CONFIG_SUPPORT_EMMC_BOOT defined. Reported by Stefan Roese with turris_mox_defconfig, thanks!
