Subject: [PATCH 0/3] PCI: emulated PCI bridge common logic
Date: Fri, 29 Jun 2018 11:22:28 +0200	[thread overview]
Message-ID: <20180629092231.32207-1-thomas.petazzoni@bootlin.com> (raw)

Hello,

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.

Best regards,

Thomas
