+Subject: [PATCH 1/4] PCI: iproc: enable arm64 support for iProc PCIe
+
+PCI: iproc: Add arm64 support
+
+Add arm64 support to the iProc PCIe driver.
+
+Note that on arm32, bus->sysdata points to the arm32-specific
+pci_sys_data struct, and pci_sys_data.private_data contains the
+iproc_pcie pointer. For arm64, there's nothing corresponding to
+pci_sys_data, so we keep the iproc_pcie pointer directly in
+bus->sysdata.
+
+In addition, arm64 does IRQ mapping in pcibios_add_device(), so it
+doesn't need pci_fixup_irqs() as arm32 does.
