Thanks for your reply. I undid all dma mapping commits with the following command:
git checkout 721c01ba8b46ddb5355bd6e6b3bbfdabfdf01e97
After that I compiled the kernels with this code for my P5020 board (Cyrus) and for my PASEMI board (Nemo) today.
Result: PASEMI onboard ethernet works again and the P5020 board boots.
It seems the dma mapping commits are the problem.
@All Could you please test Christoph's kernel on your PASEMI and NXP boards? Download:
'git clone git://git.infradead.org/users/hch/misc.git -b powerpc-dma.5 a'
Thanks, Christian
