[RFC PATCH 00/12] Create PCI root buses with correct resources

From: Bjorn Helgaas
Date: Mon Oct 10 2011 - 23:18:30 EST


The core of this series (patch 2) is due to Deng-Cheng Zhu.

The idea is that we should create PCI root buses with the correct resources,
rather than creating them with default resources and fixing them up later.
This makes the code read more naturally and prevents problems for code,
e.g., quirks, that runs between the bus creation and the fixups.

This is just an RFC because I tweaked the method of passing the root bus
resources to pci_create_bus(), I intend to extend this to a few more
architectures, and I haven't set up cross-compilers to build anything other
than x86 yet.

Bjorn Helgaas (12):
PCI: add helpers for building PCI bus resource lists
PCI: pass available resources into pci_create_bus()
MIPS: PCI: supply root bus resources to pci_create_bus()
x86/PCI: supply root bus resources to pci_create_bus()
powerpc/pci: make pcibios_setup_phb_resources() static
powerpc/pci: split PHB part out of pcibios_map_io_space()
powerpc/pci: supply root bus resources to pci_create_bus()
microblaze/pci: make pcibios_setup_phb_resources() static
microblaze/pci: supply root bus resources to pci_create_bus()
sparc/pci: supply root bus resources to pci_create_bus()
sparc/pci: use pci_create_bus() instead of pci_scan_bus_parented()
sparc/pci: supply root bus resources to pci_create_bus()
