[PATCH] stm32mp1: spl: support loading U-Boot proper from eMMC hardware partitions

[Sean Nyekjaer]

When CONFIG_SUPPORT_EMMC_BOOT is enabled, make spl_mmc_boot_mode()
return MMCSD_MODE_EMMCBOOT instead of MMCSD_MODE_RAW.

This allows the SPL MMC loader to honor the standard configuration
options CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION and
CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR when locating U-Boot proper,
whether it is stored in a GPT partition or in an eMMC hardware boot
partition.

As a result, both U-Boot SPL and U-Boot proper can be placed in the
eMMC hardware boot partitions.
