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. SEE ALSO

sda - SD/MMC architecture DESCRIPTION
The sda module provides support services for Secure Digital (SD) and MultiMediaCard (MMC) slot and card device drivers. FILES
/kernel/misc/sda 32-bit ELF kernel module (x86). /kernel/misc/amd64/sda 64-bit ELF kernel module (x86). /kernel/misc/sparcv9/sda 64-bit ELF kernel module (SPARC). ATTRIBUTES
See attributes(5) for a description of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Architecture |SPARC, x86 | +-----------------------------+-----------------------------+ |Availability |SUNWsdcard | +-----------------------------+-----------------------------+ SEE ALSO
