For most devices the boot mode maps directly to the boot device. For MMC this is not the case as we have two MMC boot modes and two MMC boot devices (ports). Check the boot port to determine which MMC device was our boot device. Make this change for both primary and secondary boot modes. Signed-off-by: Andrew F.
