Dear Jason Cooper,

Hum, well, I believe it's OK, but notice that I will very likely have
to do a followup patch, because the solution of making all PCI I/O
mappings use the MT_UNCACHED memory type, suggested by Arnd, has not
been accepted by Will Deacon. So very likely I will have to change
again the mach-mvebu/coherency.c code to call a function that makes PCI
I/O mappings MT_UNCACHED specifically for the mach-mvebu platform. But
that can indeed be a followup patch.

Ahh, my mistake.  It was late.  I saw the arm,io-coherent was settled
and mistakenly thought the other proposed changes wouldn't affect this
patch.

I could easily drop it if you like.  It's currently the tip of mvebu/soc
and I haven't done a signed tag for it yet.

I think it's OK, you can keep it: the PCI I/O mapping thing will come
as an addition.

Best regards,

Thomas
