SPL mmc device index is get based on the boot device, like - BOOT_DEVICE_MMC1 for mmc device 0 - BOOT_DEVICE_MMC2 for mmc device 1
Currently BOOT_DEVICE_MMC1 is setting both SD/eSD and MMC/eMMC boot devices in i.MX, So u-boot is loading from mmc device 0 even "if the board booting from SD/eSD or MMC/eMMC"
So, this patch set BOOT_DEVICE_MMC2 for MMC/eMMC so for MMC/eMMC the u-boot is loading from mmc device 1 and the board file need to take care if the board have different mmc device order intialization.
