I was able to compile the kernel for the AmigaOne X1000 (Nemo board with PA 
Semi PA6T-1682M SoC). It boots but the PA Semi onboard ethernet doesn't 
work.

Thanks.  But we are exactly missing the steps that are relevant.  I've
pushed a fixed up powerpc-dma.6 tree, which will only change starting from
the first commit that didn't link.

The first commit that changed from the old one is this one:

http://git.infradead.org/users/hch/misc.git/commitdiff/257002094bc5935dd63207a380d9698ab81f0775

which was that one that your compile failed on first.

Thanks again for all your work!
