: This is great progress towards a working driver. Warner Losh reported in his
: blog that Ricoh chipset works but not sure which driver he was using:

There are two different drivers for SD/MMC right now.  The one that I
wrote, which sorbo wrote a driver for the laptop bridges and the one
that umemoto-san has written about (authored by gotanda-san).  Sorbo's
driver works well on Ricoh based bridges, but fails for TI based ones.
Gotanda-san's driver has a little more support for TI bridges that
he's done in response to my testing.  I still owe him some testing on
his driver.  The down side of Gotanda-san's driver is that it doesn't
integrate into the sd/mmc infrastructure that's currently in the tree.

In other words: I'm working on it but have limited time to make
progress.
