Hi,

Takashi Iwai posted patches to make ALSA work on non-coherent PPC32
systems (almost exactly) a year ago. See here:
http://www.nabble.com/-PATCH-0-3--ALSA-fixes-for-non-coherent-ppc32-to17980027.html#a17980027

As far as I can see these patches never went upstream. Where there any
objections or did we just forget about them? It would be cool, if the
patches could be merged now, as at least two platforms need this bugfix
(namely Sam440 and AmigaOne).

I definitely forgot about those... But I'm fine with what Takashi did
for now, I can always make the powerpc helper for dma_mmap_coherent()
smarter later on if necessary.

Cheers,
Ben.
