Surely one of the preconditions then is to improve the existing PL080
dmaengine driver to do what you need it to.

I've worked on that driver to bring it closer to sanity and correctness,
and its almost there.  The problem I have working on the driver is the
crippled ARM development hardware, where most DMA just doesn't work in
one way or another.
