Bjorn, Lorenzo,

The pci-mvebu driver already contains some logic to emulate a root
port PCI bridge. It turns out that we have a similar need for the
pci-aardvark driver. Instead of duplicating the same logic in two
drivers, this patch series starts by adding a small common
infrastructure that helps emulate a root port PCI bridge, converts
pci-mvebu to use it, and finally extends pci-aardvark to use it as
well.

Thanks to this, Marvell Armada 3720 based systems, which use the
Aarkvark PCI controller, will have better PCI support, by having a
root port PCI bridge exposed.

The emulated PCI bridge common logic is a proposal, I very much
welcome comments and suggestions. Also, if you feel that adding a
common logic for only two drivers is too early, I'm fine with
duplicating a bit of code betwen pci-mvebu and pci-aardvark.

I was wondering if you had any feedback on this patch series. Not
necessarily a detailed review, but at least some general
feeling/feedback on the overall approach would be very nice.

Thanks a lot,

Thomas Petazzoni
