Subject: [PATCH 00/13] PCI: sparc related 64bit resource fixup

Hi Bjorn,

Please check sparc related 64bit resource handling patches.

patch 1-8: parse MEM64 for sparc and other system with OF.
	So device 64bit resource could find their parent resource.

patch 9-12: MMIO64 handling enhancement
        treat non-pref mmio64 as pref mmio64 if all bridges to root all pcie.

patch 13: restore old pref allocation logic if hostbridge does not support mmio64.

Those patches could be applied on top of today's pci/next.

Thanks

Yinghai


Yinghai Lu (13):
  sparc/PCI: Use correct offset for bus address to resource
  PCI: Add pci_find_bus_resource()
  sparc/PCI: Reserve legacy mmio after PCI mmio
  sparc/PCI: Add IORESOURCE_MEM_64 for 64-bit resource in OF parsing
  sparc/PCI: Keep resource idx order with bridge register number
  powerpc/PCI: Keep resource idx order with bridge register number
  powerpc/PCI: Add IORESOURCE_MEM_64 for 64-bit resource in OF parsing
  OF/PCI: Add IORESOURCE_MEM_64 for 64-bit resource
  PCI: Check pref compatible bit for mem64 resource of PCIe device
  PCI: Only treat non-pref mmio64 as pref if all bridges have MEM_64
  PCI: Add has_mem64 for struct host_bridge
  PCI: Only treat non-pref mmio64 as pref if host bridge has mmio64
  PCI: Restore pref MMIO allocation logic for host bridge without mmio64
