Thanks for the hint. I am still a git-noob ;-)

Thanks again, I was searching for documentation about dts, and couldn't find 
much.

Hmm, I know we are going to use it, but there are no drivers still...
I'll leave it out, and add it again later when axe-support has arrived.

No, it's not compatible with any other dma controller AFAIK. It special for 
this chip. John Rigby is writing the driver for it right now.

Ok, I removed also several others (all of them in this file). I hope that it 
is not a problem not making this a separate patch?

I think right now they need to. That's the way someone broke...err changed 
platform selection.

We should fix that later, but I don't really know what would be the right way 
to fix this right now. I'll think about it after this...

Btw, is it ok I just re-submit the fixed patches (with cc to linuxppc-dev)?

Thanks.
