I applied this series to my pci/host-xilinx branch for v4.6.

Michal, you only explicitly acked the last patch, but that only makes
sense if I apply the whole series, so I applied your ack to all the
patches.

Someday somebody should rework pci_fixup_irqs() so that doesn't have
to be arch-dependent.

I reworked the changelogs as below.

Bjorn

    PCI: xilinx: Don't call pci_fixup_irqs() on Microblaze

    The Xilinx AXI PCIe Host Bridge Soft IP driver was previously only
    supported on ARM (in particular, on ARCH_ZYNC), and pci_fixup_irqs() is
    available there.  But Microblaze will do IRQ fixup in pcibios_add_device(),
    so pci_fixup_irqs() is not available on Microblaze.

    Don't call pci_fixup_irqs() on Microblaze, so the driver can work on both
    Zynq and Microblaze Architectures.

    PCI: xilinx: Remove dependency on ARM-specific struct hw_pci

    The Xilinx PCIe host controller driver uses pci_common_init_dev(), which
    is ARM-specific and requires the ARM struct hw_pci.  The part of
    pci_common_init_dev() that is needed is limited and can be done here
    without using hw_pci.

    Create and scan the root bus directly without using the ARM
    pci_common_init_dev() interface.
