It's an issue with commit 1ab08790bb75e4 -- when we did a refactor
of the SD card emulation we didn't notice that the omap mmc
controller was also using the sd_cmd_type_t enum and relied
on the values of that enum matching the meanings of the
different values of the controller's MMC_CMD register Type field.
I'm just testing a patch.
