Problems with SD8686 SDIO on HTC Shift

Hello together!

Sorry for the long break, but I had other things to take care of. :)

I was not clear here: I didn't mean adding the IDs for driver mapping, 
but simply a "ID->device name" mapping, so that others don't have to 
search for the name of the device.

I compiled mmc with your suggested changes. I think - according to the 
attached dmesg output - that the changes didn't went well ^^. After 
inserting the SD card to run the tests I weren't able to unload 
mmc_block anymore.


Finally I also managed to install an older distribution (namely Xubuntu 
8.04.1 running a 2.6.24-19 kernel).
The libertas driver fails with the same problem as on Archlinux.

BUT: the driver which is mentioned in the tutorial for "Linux on Shift" 
( http://pof.eslack.org/blog/2008/04/14/linux-on-htc-shift/ ) works! 
It's in the Linux-Ubuntu-Modules Package ( 
http://archive.ubuntu.com/ubuntu/pool/main/l/linux-ubuntu-modules-2.6.24/linux-ubuntu-modules-2.6.24_2.6.24-24.38.tar.gz 
) in the directory ubuntu/wireless/marvell/8686_wlan.
For compilation (on the 2.6.24 kernel) it needs the option 
CONFIG_MMC_SD8686=m and the header os_headers.h in os/linux must be 
fixed: it includes "<semaphore.h>" but it must be "<asm/semaphore.h>".
For the firmware one can use the v9 ones from the kernel repo. Their 
destination directory is {firmwaredir}/mrvl and the helper must be 
called helper_sd.bin.

The interesting part is: this driver also relies on mmc_core, but it 
doesn't fail like libertas. There are indeed no errors in dmesg. So 
where is the problem now? Is it not only in mmc, but also in 
libertas(_sdio)? How does sd8686.ko circumvent the problems with this 
strange SD-controller?

Hmm... I will recompile mmc in debug mode. I hope this will clear up 
some things :D

Greetings,
Sven
