Subject: [RESEND PATCH v3 0/2] Pass resources to pci_create_bus() and fix MIPS PCI resources
Date: Thu, 1 Sep 2011 10:48:27 +0800	[thread overview]
Message-ID: <1314845309-3277-1-git-send-email-dczhu@mips.com> (raw)

(Resending the patch set to include more arch maintainers.)

Change the pci_create_bus() interface to pass in available resources to get them
settled down early. This is to avoid possible resource conflicts while doing
pci_scan_slot() in pci_scan_child_bus(). Note that pcibios_fixup_bus() can get
rid of such conflicts, but it's done AFTER scanning slots.

In addition, MIPS PCI resources are now fixed using this new interface.

-- Changes --
v3 - v2:
o Do not do fixups for root buses in pcibios_fixup_bus().
o Skip bus creation when bus resources cannot be allocated.
o PCI domain/bus numbers added to the error info in controller_resources().

v2 - v1:
o Merge [PATCH 1/3] to [PATCH 3/3], so now 2 patches in total.
o Add more info to patch description.
o Fix arch breaks in default resource setup discovered by Bjorn Helgaas.
