-/*
- This is the AT91 MCI driver that has been tested with both MMC cards
- and SD-cards. Boards that support write protect are now supported.
- The CCAT91SBC001 board does not support SD cards.
-
- The three entry points are at91_mci_request, at91_mci_set_ios
- and at91_mci_get_ro.
-
- SET IOS
- This configures the device to put it into the correct mode and clock speed
- required.
-
- MCI REQUEST
- MCI request processes the commands sent in the mmc_request structure. This
- can consist of a processing command and a stop command in the case of
- multiple block transfers.
-
- There are three main types of request, commands, reads and writes.
-
- Commands are straight forward. The command is submitted to the controller and
- the request function returns. When the controller generates an interrupt to indicate
- the command is finished, the response to the command are read and the mmc_request_done
- function called to end the request.
-
- Reads and writes work in a similar manner to normal commands but involve the PDC (DMA)
- controller to manage the transfers.
-
- A read is done from the controller directly to the scatterlist passed in from the request.
- Due to a bug in the AT91RM9200 controller, when a read is completed, all the words are byte
- swapped in the scatterlist buffers. AT91SAM926x are not affected by this bug.
-
- The sequence of read interrupts is: ENDRX, RXBUFF, CMDRDY
-
- A write is slightly different in that the bytes to write are read from the scatterlist
- into a dma memory buffer (this is in case the source buffer should be read only). The
- entire write buffer is then done from this single dma memory buffer.
-
- The sequence of write interrupts is: ENDTX, TXBUFE, NOTBUSY, CMDRDY
-
- GET RO
- Gets the status of the write protect pin, if available.
