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.
