pci: PCIe driver for Marvell Armada 370/XP systems
This driver implements the support for the PCIe interfaces on the Marvell Armada 370/XP ARM SoCs. In the future, it might be extended to cover earlier families of Marvell SoCs, such as Dove, Orion and Kirkwood. The driver implements the hw_pci operations needed by the core ARM PCI code to setup PCI devices and get their corresponding IRQs, and the pci_ops operations that are used by the PCI core to read/write the configuration space of PCI devices. Since the PCIe interfaces of Marvell SoCs are completely separate and not linked together in a bus, this driver sets up an emulated PCI host bridge, with one PCI-to-PCI bridge as child for each hardware PCIe interface. In addition, this driver enumerates the different PCIe slots, and for those having a device plugged in, it sets up the necessary address decoding windows, using the mvebu-mbus driver.
