Hello everybody,

I've found that mpc512x_dma doesn't work reliable in my tests (dmatest
module and NetPipe with CONFIG_NET_DMA enabled).
These patches fixes two issues I've found: inproper handling of
scatter/gather transfers and missing interrupts.
The third patch adds support for MPC8308 which has pretty much the same
DMA controller as MPC5121.

The first patch has an issue: I'm accessing IO space with direct memory
access not via accessor functions. I don't know how to use accessor
functions with bitfield structures.

Any comments would be appreciated.

With these patches applied my tests succeed both on MPC5121 and MPC8308.

Regards, Ilya.
