[GIT PULL] Generic PCI host controller driver for 3.16

[Will Deacon]

Hi Bjorn,

Please can you pull my generic PCI host controller driver for 3.16?

It's been doing the rounds on the lists for some time and things have
settled down now, despite a recent failed attempt at factoring out the
configuration space accessors.

Cheers,

Will

Is this the same as patches 2 & 3 of your v7 series of May 23?

The only thing I see that is actually ARM-specific is the
pci_common_init_dev() call and struct hw_pci usage.  That makes sense at
this stage of development.  Maybe someday we'll be able to abstract this
enough to make it truly arch-agnostic.

Yes, they're identical so you can just pick the two patches from there if
you prefer.

Indeed. I'm hoping Liviu continues with his PCI work for arm64, then I can
port this driver over to that eventually.

Cheers,

Will

Great, just wanted to make sure these had been on the list and that
you didn't need me to pick up patch 1 ("ARM: kconfig: allow PCI
support to be selected with ARCH_MULTIPLATFORM") or 4 ("PCI: Generic
Configuration Access Mechanism support").

I put this on my pci/host-generic branch for v3.16, thanks!
