[tlinux-users:07901] Toshiba A105 SD card reader.

I just updated to kernel 2.6.17, and I have managed to get the SD
card reader working. It is not as nice as it could be, but it does
work. I adapter what someone else had working for the PCIxx21 and
modified it for the PCIxx12 in the Toshiba. Here is what I did.

modprobe -r mmc_block
modprobe -r sdhci
setpci -s 04:06.3 86.b=90
setpci -s 04:06.2 4c.b=02 # FlashMedia SD disable
setpci -s 04:06.3 04.b=06 # SDHCI Mem+ BusMaster+
setpci -s 04:06.3 88.b=01 # SDHCI DMA enable
modprobe sdhci
modprobe mmc_block

The SD card shows up as /dev/mmcblk0 and you will want to mount
/dev/mmcblk0p1 for most cards. mmcblk0 is the entire card, and
mmcblk0p1 is the FAT16 partition on the card I am using.

Depending on where you run the commands, you may not need the two
modprobe -r commands, but they will not hurt. You only need to run
the sequence of commands once per boot, as the reader stays in the
proper mode when you change cards. Be warned, if you copy a large
amount of data to the card, and then unmount it, it may take a while
to write all the data to the card.
