Dropped due to build errors on powerpc64. 3.11 material now.

Wait! That means dropping _all_ the change done in mvebu for 3.10 just
for one patch in the of/pci part?

Jason, did you take the accurate patch? Because according to Grant
Likely, the build didn't fail on ppc, see:

I investigated it a little more and my first assumption was wrong,
the faulty commit was not the one I think. I didn't work directly
on the PCIe part, and Thomas who did it is currently in the plane.

So instead of throwing everything, could you just remove the
offending commit, AFAIK we don't need it yet, (the patch
depending of this one are located in the mvebu-late/pcie branch):

9ecbe03 pci: infrastructure to add drivers in drivers/pci/host

Thanks!

I thought the faulty commit with in the MIPS patch (last patch in the
set). And a patch to fix this was prepared by Gabor Juhos [2].

Or is there another faulty commit in my v7 set [1]? If you let me know
I can fix it
