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

Next step: 4558b6e1ddf3dcf5a86d6a5d16c2ac1600c7df39 (swiotlb: remove 
swiotlb_dma_supported)

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

git checkout 4558b6e1ddf3dcf5a86d6a5d16c2ac1600c7df39

Output:

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

   git checkout -b <new-branch-name>

HEAD is now at 4558b6e... swiotlb: remove swiotlb_dma_supported

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

Results: PASEMI onboard ethernet (X1000) 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.
