Hi,
This patch series adds PCIe root complex support for AM654x SoC.
The device-tree files are based on bindings accepted in linux. See files Documentation/devicetree/bindings/phy/ti,phy-am654-serdes.txt and Documentation/devicetree/bindings/pci/pci-keystone.txt in latest mainline master.
I have not posted the actual board-specific device-tree bits yet. The reason is that PCIe slot is on a daughter card on the AM65x EVM. I want to see how we can support that as an overlay in U-Boot. That needs some more attention. Meanwhile I have tested this using a patch that simply enables PCIe in the baseboard device-tree file itself.
