As originally reported against beagleboard we currently have the following error message reported in SPL:
U-Boot SPL 2012.04-00020-gb8310b9-dirty (Apr 25 2012 - 18:49:57) Texas Instruments Revision detection unimplemented OMAP SD/MMC: 0 timed out in wait_for_bb: I2C_STAT=1000 reading u-boot.img ....
The reason for above message is that when booting from MMC, I2C needs to be initialized to talk with the TWL4030. On OMAP3 I2C is only initalized in SPL if CONFIG_SPL_BOARD_INIT is set.
