NAME
     mmc — MultiMediaCard and SD Card bus driver


SYNOPSIS
     device mmc


DESCRIPTION
     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.
