Yeah that was never the intention, the Samsung derivate has one extra
Register and other funny stuff.

I was more hoping on breaking out a subset in the same elegant way
with a generic part and a separate DMAengine as was done with the
PL330... But I need to get it fully working first.

Atleast I used the same include file.

But I have functional UART DMA on the RealView PB11MPCore now!

Yours,
