Could you check what is the status of following defines in your .config
file:

CONFIG_SPL_FAT_SUPPORT
CONFIG_SUPPORT_EMMC_BOOT

And if by any chance your don't have:
CONFIG_SPL_EXT_SUPPORT defined?

From what you have written above I assume that you boot from the
same medium - i.e. eMMC (so SPL and u-boot.img are on the same medium) ?
