We have a few options here:

1) Take the patch as I posted it (needs adjustments as soon as the API
changed and becomes stable)

2) Remove the DMA related patches from the LPC32xx series for now (which
would be unfortunate)

3) Let me build upon some tree that already looks worthwhile to play
with already (which one?)

What would you suggest?

Thanks in advance,

Roland
