RE: MPC8540 DMA routines (channel 0 broken?)

In the meanwhile, I got channel 0 working. It seems
that the DMA#0 machine got stuck in some configuration from any
previous (u-boot?) operation which didn't clean up things
properly. I had to explicitly abort a (continously running?)
transfer to be able to re-program it in the way I need.

Are you using a BDI2000?=20
Some init mode uses the DMA#0 for memory zeroing (see your .cfg file).
Also the DDR ECC U-boot code may use the DMA#0.
Isn't it possible to reset the DMA#0 from Linux?
