NAME
sdhci -- PCI SD Host Controller bridge driver SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file: device mmc device mmcsd device sdhci Alternatively, to load the driver as a module at boot time, place the following lines in loader.conf(5): mmc_load="YES" mmcsd_load="YES" sdhci_load="YES" DESCRIPTION
The sdhci 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 remov- ing. HARDWARE
The sdhci driver supports different specification compatible chips. The following chips have been verified to work: o ENE CB712 o ENE CB714 o RICOH R5C822 o RICOH R5CE823 o TI PCIXX21/XX11 SEE ALSO

Alexander Motin <mav@FreeBSD.org> BUGS
Many of existing SD controller chips have some nonstandard requirements, proprietary registers and hardware bugs, requiring additional han- dling. ENE chips are handled to work fine, while some revisions of RICOH and TI controllers still do not see cards without some additional initialization. BSD

NAME
iir -- Intel Integrated RAID controller and ICP Vortex driver SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file: device pci device scbus device iir Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): iir_load="YES" DESCRIPTION
The iir driver claims to interface with the Intel integrated RAID controller cards, and all versions of the ICP Vortex controllers (including FC). HARDWARE
Controllers supported by the iir driver include: o Intel RAID Controller SRCMR o Intel Server RAID Controller U3-l (SRCU31a) o Intel Server RAID Controller U3-1L (SRCU31La) o Intel Server RAID Controller U3-2 (SRCU32) o All past and future releases of Intel and ICP RAID Controllers. o Intel RAID Controller SRCU21 (discontinued) o Intel RAID Controller SRCU31 (older revision, not compatible) o Intel RAID Controller SRCU31L (older revision, not compatible) The SRCU31 and SRCU31L can be updated via a firmware update available from Intel.
