Please have a look at the commit message of 07/22.
This is done intentionally to be generic enough to be used for any
media. We intend to add NAND support to the same SPL for OMAP3/4. You
can potentially have the same SPL support MMC *and* NAND. Where it
loads the U-Boot from will depend on a switch setting on the board.

best regards,
Aneesh
