* PCI: Provide a default pcibios_update_irq()Thierry Reding2012-09-181-9/+0
| | | | | | | | | Most architectures implement this in exactly the same way. Instead of having each architecture duplicate this function, provide a single implementation in the core and make it a weak symbol so that it can be overridden on architectures where it is required.

* PCI: Discard __init annotations for pci_fixup_irqs() and related functionsThierry Reding2012-09-181-1/+1
| | | | | | | | | | | Remove the __init annotations in order to keep pci_fixup_irqs() around after init (e.g. for hotplug). This requires the same change for the implementation of pcibios_update_irq() on all architectures. While at it, all __devinit annotations are removed as well, since they will be useless now that HOTPLUG is always on.

* sparc/PCI: factor out pcibios_setup()Myron Stowe2012-07-051-8/+0
| | | | | | | | The PCI core provides a generic pcibios_setup() routine. Drop this architecture-specific version in favor of that. Acked-by: David S. Miller <davem@davemloft.net> Signed-off-by: Myron Stowe <myron.stowe@redhat.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

* sparc/PCI: get rid of device resource fixupsBjorn Helgaas2012-02-231-40/+7
| | | | | | | | | | | | | | | | | Tell the PCI core about host bridge address translation so it can take care of bus-to-resource conversion for us. N.B. Leon apparently never uses initial BAR values, so it didn't matter that we never fixed up the I/O resources from bus address to CPU addresses. Other sparc uses pci_of_scan_bus(), which sets device resources directly to CPU addresses, not bus addresses, so it didn't need pcibios_fixup_bus() either. But by telling the core about the offsets, we can nuke pcibios_resource_to_bus(). CC: "David S.

* sparc32, leon/PCI: convert to pci_scan_root_bus() for correct root bus resourcesBjorn Helgaas2012-01-061-17/+8
| | | | | | | | | | | | | 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.

* sparc: add export.h to arch/sparc files as requiredPaul Gortmaker2011-10-311-0/+1
| | | | | | | | | These files are only exporting symbols, so they don't need the full module.h header file. Previously they were getting access to EXPORT_SYMBOL implicitly via overuse of module.h from within other .h files, but that is being cleaned up.

* sparc32,leon: added LEON-common low-level PCI routinesDaniel Hellstrom2011-06-021-0/+253
The LEON architecture does not have a BIOS or bootloader that initializes PCI for us, instead Linux generic PCI layer is used to set up resources and IRQ. Signed-off-by: Daniel Hellstrom <daniel@gaisler.com> Signed-off-by: David S. Miller <davem@davemloft.net>
