SubjectRe: use generic DMA mapping code in powerpc V4
From
Date
Hi All,

I compiled the fixed '257002094bc5935dd63207a380d9698ab81f0775'
(powerpc/dma: use the dma-direct allocator for coherent platforms) today.

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

git checkout 257002094bc5935dd63207a380d9698ab81f0775

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


env LANG=C make CROSS_COMPILE=powerpc-linux-gnu- ARCH=powerpc zImage

env LANG=C make CROSS_COMPILE=powerpc-linux-gnu- ARCH=powerpc uImage

The X1000 boots and the PASEMI onboard ethernet works!

Bad news for the X5000 (P5020 board). U-Boot loads the kernel and the
dtb file. Then the kernel starts but it doesn't find any hard disks
(partitions).

Cheers,
Christian

So 257002094bc5935dd63207a380d9698ab81f0775 above is the fixed version
for the commit - this switched the ifdef in dma.c around that I had
inverted.  Can you try that one instead?  And then move on with the
commits after it in the updated powerpc-dma.6 branch - they are
identical to the original branch except for carrying this fix forward.
