Hi Sebastian

I only tried it on Kirkwood. I've had similar bug reports for 370,
which appears to shares the same IP core.

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.

No, not at all. I just wanted to point out, there are known problems
with the in kernel driver for MVSDIO.
