[PATCH v6 0/2] PCI: allocate 64bit mmio pref

From: Yinghai Lu
Date: Thu Dec 19 2013 - 15:43:51 EST


mmio 64 allocation that could help Guo Chao <yan@xxxxxxxxxxxxxxxxxx> on powerpc mmio allocation.
It will try to assign 64 bit resource above 4g at first.

And it is based on current pci/next and pci/resource.

-v2: update after patch that move device_del down to pci_destroy_dev.
add "Try best to allocate pref mmio 64bit above 4G"

-v3: refresh and send out after pci_clip_resource() changes,
as Bjorn is not happy with attachments.

-v4: make pcibios_resource_to_bus take bus directly.

-v5: fix non-pref mmio64 allocation problem found by Guo Chao.
refresh last three as Bjorn update first two and put them in pci/resource

-v6: try above 4G at first, then restart again for under 4G.
so we can drop patch that sort pci root bus resource list.

PCI: Try to allocate mem64 above 4G at first
PCI: Try best to allocate pref mmio 64bit above 4g
