powerpc/pci: Remove redundant pcnet32 fixup

2009-05-21T05:44:24+00:00

The pcnet32 driver has had in its device id table for some time a match
against the "broken" vendor ID.  No need to fake out the vendor ID
with an explicit fixup.

powerpc/pci: Cleanup some minor cruft

2009-05-21T05:44:24+00:00

* Removed building setup-irq on ppc32, we don't use it anymore
* Remove duplicate prototype for setup_grackle() code that needs it
  gets it from 
* Removed gratuitous pci_io_size type differences between ppc32/ppc64

powerpc/pci: Fix PCI<->OF matching of old style multifunc devices

2009-02-22T23:48:57+00:00

Old OF variants used to create a 'dummy' parent node "multifunc-device"
for devices with more than one PCI function. Our code that matches OF
nodes to PCI devices dealt with that in one place but not in another,
this fixes it.

This has the practical effect of fixing interrupt routing of multifunction
PCI cards on some older PowerMac machines.

powerpc/pci: Move hose_list and pci_address_to_pio to pci-common

2009-02-11T05:00:07+00:00

move the definition of hose_list next to its hotplug spinlock.

create pcibios_io_size to encapsulate ifdef in existing pci-common
function pcibios_vaddr_is_ioport

move pci_address_to_pio to pci-common, using new pcibios_io_size, and
protect this GPL exported function against concurrent hotplug removal

powerpc: Remove `have_of' global variable

2008-12-16T04:52:57+00:00

The `have_of' variable is a relic from the arch/ppc time, it isn't
useful nowadays.

powerpc/pci: Remove pcibios_do_bus_setup()

2008-11-05T11:11:53+00:00

The function pcibios_do_bus_setup() was used by pcibios_fixup_bus()
to perform setup that is different between the 32-bit and 64-bit
code.  This difference no longer exists, thus the function is removed
and the setup now done directly from pci-common.c.

powerpc/pci: Use common PHB resource hookup

2008-11-05T11:11:53+00:00

The 32-bit and 64-bit powerpc PCI code used to set up the resource
pointers of the root bus of a given PHB in completely different
places.

This unifies this in large part, by making 32-bit use a routine very
similar to what 64-bit does when initially scanning the PCI busses.

The actual setup of the PHB resources itself is then moved to a
common function in pci-common.c.

This should cause no functional change on 64-bit.  On 32-bit, the
effect is that the PHB resources are going to be setup a bit earlier,
instead of being setup from pcibios_fixup_bus().

powerpc/pci: Cleanup debug printk's

2008-11-05T11:11:53+00:00

This removes the various DBG() macro from the powerpc PCI code and
makes it use the standard pr_debug instead.

powerpc: Fix link errors on 32-bit machines using legacy DMA

2008-10-14T23:13:29+00:00

The new merged DMA code will try to access isa_bridge_pcidev when
trying to DMA to/from legacy devices. This is however only defined
on 64-bit. Fixes this for now by adding the variable, even if it
stays NULL. In the long run, we'll make isa-bridge.c common to
32 and 64-bit.

powerpc/fsl: Hide MPC5121 pci bridge.

2008-10-13T16:09:58+00:00

The class of the MPC5121 pci host bridge is PCI_CLASS_BRIDGE_OTHER
while other freescale host bridges have class set to
PCI_CLASS_PROCESSOR_POWERPC.

This patch makes fixup_hide_host_resource_fsl match
PCI_CLASS_BRIDGE_OTHER in addition to PCI_CLASS_PROCESSOR_POWERPC.
