Does the SD card work in the first stage loader? If yes, you could try
to remove the mux setup from barebox, so that you can be sure that you
do not misconfigure things that were already configured correctly.
I have no hardware handy to test the driver on a i.MX25, but Erics
Eukrea board has MMC support, so I believe the driver should work in
general.
