Cover letter [PATCH 0/3] PCI: emulated PCI bridge common logic

Bjorn, Lorenzo,

Quoted 8 lines · Thomas Petazzoni

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
