question about the SD card reader

Hi,

First I don't have an iPaq but an eten G500. It is based on a s3c2440, as the
rx3715. So I am quite off topic but maybe someone can help me...

My first question is perhaps a stupid question (sorry) : the h1930/h1940
devices use the s3c2410mci driver for SD card access. As far as I can see
this driver should also perfectly work with the s3c2440 (same registers, same
logic, etc). But I noticed the rx3715 based on a s3c2440 don't use the
s3c2410 driver, but the asic3 instead. As anybody an idea of why the rx3715
does not use the builtin s3c2440 controller ?

My second question is about the s3c2410mci driver in itself. I read a post on
this mailing list http://www.handhelds.org/hypermail/rx3700-port/2/0202.html
which deals with this driver. The last lines of the post shows the message
log of the driver. It is exactly what I get on my device with the s3c2410mci
driver, and this is because the driver does not receive interrupt request
from the SD card module, the command request is blocked on
a "wait_for_completion" call. So my question is : could it means that there
is no hardware plugged on the s3c24xx MMC/SD/SDIO controller ? I checked the
SDI command status register and it tells me the command has been sent (bit 11
set).
I made some tests with the asic3 driver but with no result.

best regards,

Pierre Hebert.
