Loading U-Boot on i.MX8QXP MEK board is broken since recent changes in spl_mmc:
U-Boot SPL 2019.10-00162-gff5bd397e4 (Oct 18 2019 - 15:50:45 +0200) Normal Boot WDT: Not found! Trying to boot from MMC2_2 Load image from MMC/SD 0x46400 spl: mmc partition switch failed SPL: failed to boot from all boot devices ### ERROR ### Please RESET the board ###
The newly added CONFIG_SYS_MMCSD_RAW_MODE_EMMC_BOOT_PARTITION option is selected automatically and overrides the EXT_CSC_PART_CONFIG configurations with default value, always selecting the eMMC boot partition 1. Boards which place U-Boot image in other partitions became not bootable.
Fix this by making the eMMC HW boot partition selection optional.
Fixes: 17241ea0543a (spl: mmc: Add option to set eMMC HW boot partition) Signed-off-by: Anatolij Gustschin agust@denx.de --- Hi Tom,
Many other boards (using CONFIG_SUPPORT_EMMC_BOOT) are affected, too. So, this (or other suitable fix) should be applied ASAP.
Thanks, Anatolij
