The amount of code that will be modified or taken out of drivers/dma/pl330_dmac
will so much that I will be left only with constrained data structures in
the file to do tricks to make it work with the PL330 engine driver.
I am not very keen on authoring the driver/dma/ driver but neither am I
interested in having to cleanup someone else' code.

I'll post in a day or two when the PL330 core driver takes come shape
closer to what it is supposed to look.
That will help me getting suggestions for improvement, i hope.
