Use kernel command line parameter pci=pcie_bus_perf to work with Keystone PCI Controller. Following patch addressed this. [PATCH v1] ARM: pci: add call to pcie_bus_configure_settings() - Add documentation for device tree bindings - Add separate interrupt controller nodes for MSI and Legacy IRQs and use irq map for legacy IRQ - Use compatibility to identify v3.65 version of the DW hardware and use it to customize the designware common code. - Use reg property for configuration space instead of range - Other minor updates based on code inspection. V1 - Add an interrupt controller node for Legacy irq chip and use interrupt map/map-mask property to map legacy IRQs A/B/C/D - Add a Phy driver to replace the original serdes driver - Move common application register handling code to a separate file to allow re-use across other platforms that use older DW PCIe h/w - PCI quirk for maximum read request size. Check and override only if the maximum is higher than what controller can handle. - Converted to a module platform driver.
