iMx 258 MMC access speed

I'm having problems with one board using iMx 258, facing slow timings when accessing the MMC slot. I was told by the board supplier it was a problem with the kernel driver, originally detected in other processors, but that seemed to affect the iMx258 as well, and they were waiting for Freescale to release a new kernel version fixing the problem, though they had no estimate.

 

Along with the low speed accesses, we face MMC (uSD) card errors after some time, even when using industrial uSD cards.

 

As this problem been fixed already, or, if not, is there an estimate for fixing this?
