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
