.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver implements the MMC and SD Card bus.
|
|
The
|
|
.Nm
|
|
driver supports all MMC and SD bridges in the system.
|
|
All SD or MMC cards in the system attach to an instance of
|
|
.Nm .
|
|
The
|
|
.Nm
|
|
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.
