Hi Sebastian I only tried it on Kirkwood. I've had similar bug reports for 370, which appears to shares the same IP core. > Dove is using a different SDHCI compatible SDIO controller. Ah, O.K. Didn't know. It will be interesting to see if this core has the same problems, i.e. shares the same DMA engine as the MVSDIO core. > Also, the DMA issue is not holding back this patch, is it? No, not at all. I just wanted to point out, there are known problems with the in kernel driver for MVSDIO.
