This patch adds a PCIe controller driver for Keystone SoCs. This is based on the origin RFC patch that I had sent earlier. I have incorporated following comments:- - Add a 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 applicaiton 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.
