    pci: PCIe driver for Marvell Armada 370/XP systems · 45361a4f

    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.
