SPL: Add CONFIG_SUPPORT_EMMC_BOOT support to CONFIG_SPL_FRAMEWORK
We use the switch CONFIG_SUPPORT_EMMC_BOOT today to enable some additional features of the eMMC boot partitions. Add support for being told that we have booted from one of these partitions to the spl framework and implement this on TI OMAP/related.
