The mmc driver implements the MMC and SD
Card bus. The mmc driver supports all MMC and SD
bridges in the system. All SD or MMC cards in the system attach to an
instance of mmc. The mmc bus
typically has only one slot, and only memory cards. MultiMediaCards exist
only in memory. SD Cards exist as memory, I/O, or combination cards.
