|
|
|
To compile this driver into the kernel, place the following lines in your
|
|
|
|
|
kernel configuration file:
|
|
|
|
|
.Bd -ragged -offset indent
|
|
|
|
|
.Cd "device mmc"
|
|
|
|
|
.Cd "device mmcsd"
|
|
|
|
|
.Cd "device sdhci"
|
|
|
|
|
.Ed
|
|
|
|
|
.Pp
|
|
|
|
|
Alternatively, to load the driver as a module at boot time, place the
|
|
|
|
|
following lines in
|
|
|
|
|
.Xr loader.conf 5 :
|
|
|
|
|
.Bd -literal -offset indent

.Sh DESCRIPTION
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
|
|
|
|
driver supports PCI devices with class 8 and subclass 5 according to
|
|
|
|
|
SD Host Controller Specification.
|
|
|
|
|
Driver supports up to six high speed 4bit MMC/SD slots per controller.
|
|
|
|
|
Driver attaches mmc bus to the respective slot on card insertion and
|
|
|
|
|
detaches it on card removing.

.Sh BUGS
|
|
|
|
|
Many of existing SD controller chips have some nonstandard requirements,
|
|
|
|
|
proprietary registers and hardware bugs, requiring additional handling.
|
|
|
|
|
ENE chips are handled to work fine, while some revisions of RICOH and TI
|
2013-04-11 18:46:41 +00:00
|
|
|
controllers still do not see cards without some additional initialization.
