This code has not been tested on a "legacy" ARM PL180 but only for
ux500 boards. Even if it should affect DMA handling we should test
this properly. Would be great if you were able to help out, I guess
you still have available hardware for these tests?

I can test the Integrator/CP and Realview in IRQ/PIO mode and
the U300 in DMA mode.

Great!

I need some help to provoke errorpath in DMA mode though,
so any hints are welcome...

One good option could be to stress test card insert/removal sequences,
while at the same time doing read/write requests.
