This is a RFC to add Keystone pcie driver. I had some earlier discussion on the pcie mailing about this driver and at that time I didn't have the driver ported to dw core driver. I now have a driver working with intel's e1000e ethernet driver and want to review this RFC on this list.
Kestone PCIE hardware is based on dw version 3.65. It lacks ATU port and standard MSI controller found in newer version of the dw hardware. This version uses registers in PCIE application space to configure MSI controller. It has 4 host irqs for legacy IRQs A/B/C/D and 8 host irqs to muliplex 32 MSI irqs. Also has one host irq line for errors. Please review and provide your comments.
