Unfortunately we didn't notice that this enum is not used solely inside the SD card model itself, but is also used by the OMAP MMC controller device. In the OMAP MMC controller, it is used to implement the handling of the Type field of the MMC_CMD register, so changing the enum values so that they no longer lined up with the bit definitions for that register field broke the controller model. The effect is that Linux fails to boot from an SD card on the "sx1" machine. Give omap-mmc its own enum which we can document as needing to match the encoding used in this device's register, so it isn't sharing sd_cmd_type_t with the SD card model any more. We can then move sd_cmd_type_t's definition out of sd.h and into sd.c, which is the only place that uses it.
