2012-01-06x86/PCI: use pci_scan_bus() instead of pci_scan_bus_parented()Bjorn Helgaas
This doesn't change any functionality, but it makes a subsequent patch slightly simpler. pci_scan_bus(NULL, ...) and pci_scan_bus_parented() are identical except that pci_scan_bus() also calls pci_bus_add_devices(): pci_scan_bus_parented pci_create_bus pci_scan_child_bus pci_scan_bus pci_create_bus pci_scan_child_bus pci_bus_add_devices All callers of pcibios_scan_root() call pci_bus_add_devices() explicitly, and we don't pass a parent device, so we might as well use pci_scan_bus().

2012-01-06x86/PCI: read Broadcom CNB20LE host bridge info before PCI scanBjorn Helgaas
We currently read the CNB20LE aperture information in a PCI quirk, which happens after we've already created the root bus. This patch changes it to read the apertures earlier so we can create the root bus with the correct resources. I believe the CNB20LE lives at "pci 0000:00:00" based on https://lkml.org/lkml/2010/8/13/220 CC: Ira W.

2012-01-06sparc32, leon/PCI: convert to pci_scan_root_bus() for correct root bus resourcesBjorn Helgaas
Convert from pci_scan_bus_parented() to pci_scan_root_bus() and remove root bus resource fixups. This fixes the problem of "early" and "header" quirks seeing incorrect root bus resources. pci_scan_root_bus() also includes the pci_bus_add_devices() so we don't need to do that separately.

2012-01-06x86/PCI: amd: Kill misleading message about enablement of IO access to PCI ECS]Andreas Herrmann
Commit 24d9b70b8c679264756a6980e668b96b3f964826 (x86: Use PCI method for enabling AMD extended config space before MSR method) added a message when IO access to PCI ECS was enabled via access to the NB_CFG PCI register. This can lead to a bogus message like [ 0.365177] Extended Config Space enabled on 0 nodes which is misleading because IO ECS access is subsequently enabled for AMD CPUs (that support this) by modifying the corresponding NB_CFG MSR. Furthermore it's not "Extended Config Space" that is enabled by this register setting. It's the IO access that is enabled for extended configruation space. IMHO the ambiguous message needs to be cancelled.

2012-01-06PCI: Pull PCI 'latency timer' setup up into the coreMyron Stowe
The 'latency timer' of PCI devices, both Type 0 and Type 1, is setup in architecture-specific code [see: 'pcibios_set_master()']. There are two approaches being taken by all the architectures - check if the 'latency timer' is currently set between 16 and 255 and if not bring it within bounds, or, do nothing (and then there is the gratuitously different PA-RISC implementation). There is nothing architecture-specific about PCI's 'latency timer' so this patch pulls its setup functionality up into the PCI core by creating a generic 'pcibios_set_master()' function using the '__weak' attribute which can be used by all architectures as a default which, if necessary, can then be over-ridden by architecture-specific code.
