Subject: Re: use generic DMA mapping code in powerpc V4

Next step: a64e18ba191ba9102fb174f27d707485ffd9389c (powerpc/dma: remove 
dma_nommu_get_required_mask)

git clone git://git.infradead.org/users/hch/misc.git -b powerpc-dma.6 a

git checkout a64e18ba191ba9102fb174f27d707485ffd9389c

Link to the Git: 
http://git.infradead.org/users/hch/misc.git/shortlog/refs/heads/powerpc-dma.6

Results: PASEMI onboard ethernet works and the X5000 (P5020 board) 
boots. I also successfully tested sound, hardware 3D acceleration, 
Bluetooth, network, booting with a label etc. The uImages work also in a 
virtual e5500 quad-core QEMU machine.
