TI FlashMedia driver

TI FlashMedia driver

[Ian E. Morgan]

Given the number of people annoyed by the lack of a driver for TI's
FlashMedia controller (part of the 6xx1 & 7xx1 series chips), myself one of
them, I've started a project to reverse-engineer the device.

Basic details available here, adding new info whenever I get/discover it:
http://www.webcon.ca/~imorgan/tifm21/

Anyone with one of these devices (common in newer notebooks, especially
HP/Compaq units) interested in helping, please check out the above web page
and get on board!

P.S. There are a few reports that a company has already written a Linux
driver for this device, but it was only made available to Texas Instruments.
Although TI's documents do mention Linux support for these devices, there is
absolutely no sign of a driver available anywhere. Queries to TI by myself
any several other people in the past have gone unanswered.

Regards,
Ian Morgan

There is some information about at least MMC controllers at:

The controller your working with is found here:

 From your page:

All controllers I've seen so far either give raw access to the MMC bus 
or completely abstracts the MMC bits (making it a USB storage device or 
similar). In other words, you probably won't see any information other 
than the fact that a card has been inserted.
