I have here a MPC8544 DS board and I tried to utilise the dma
controller. For the transfers I need set the [S|D]AHE bit in the Mode
Register. This seems to be implemented but is currently unused in the
driver. I haven't found a way how to set this bit except globally for
the whole channel.
Is it possible to solve this nicely except dedicating one channel for
such an operation?
