freebsd-dev/sys/dev/rtsx/rtsx.c
Jung-uk Kim 926ce35a7e Port rtsx(4) driver for Realtek SD card reader from OpenBSD. 
This driver provides support for Realtek PCI SD card readers.  It attaches
mmc(4) bus on card insertion and detaches it on card removal.  It has been
tested with RTS5209, RTS5227, RTS5229, RTS522A, RTS525A and RTL8411B.  It
should also work with RTS5249, RTL8402 and RTL8411.

/*
* We use two DMA buffers: a command buffer and a data buffer.
*
* The command buffer contains a command queue for the host controller,
* which describes SD/MMC commands to run, and other parameters. The chip
* runs the command queue when a special bit in the RTSX_HCBAR register is
* set and signals completion with the RTSX_TRANS_OK_INT interrupt.
* Each command is encoded as a 4 byte sequence containing command number
* (read, write, or check a host controller register), a register address,
* and a data bit-mask and value.
* SD/MMC commands which do not transfer any data from/to the card only use
* the command buffer.
*
* The data buffer is used for transfer longer than 512. Data transfer is
* controlled via the RTSX_HDBAR register and completion is signalled by
* the RTSX_TRANS_OK_INT interrupt.
*
* The chip is unable to perform DMA above 4GB.
