ARM: PCI: remove per-pci_hw list of buses

2012-05-16T14:24:12+00:00

No one uses the per-hw list of buses, so get rid of this.  Instead,
build the list locally.

ARM: PCI: provide a default bus scan implementation

2012-05-13T16:12:17+00:00

Most PCI implementations perform simple root bus scanning.  Rather than
having each group of platforms provide a duplicated bus scan function,
provide the PCI configuration ops structure via the hw_pci structure,
and call the root bus scanning function from core ARM PCI code.

ARM: PCI: get rid of pci_std_swizzle()

2012-05-13T16:12:16+00:00

Most PCI implementations use the standard PCI swizzle function, which
handles the well defined behaviour of PCI-to-PCI bridges which can be
found on cards (eg, four port ethernet cards.)

Rather than having almost every platform specify the standard swizzle
function, make this the default when no swizzle function is supplied.
Therefore, a swizzle function only needs to be provided when there is
something exceptional which needs to be handled.

This gets rid of the swizzle initializer from 47 files, and leaves us
with just two platforms specifying a swizzle function: ARM Integrator
and Chalice CATS.

ARM: PCI: remove unused sys->hw

2012-04-26T10:05:38+00:00

Some platforms mark their hw_pci structure as __initdata, which means
it will be discarded after init time.  Storing pointers to __initdata
in long lived data structures is a potential source of problems, and
in this case, sys->hw is unused apart from its initialization.

So, lets remove this member and its initializer.

arm/PCI: don't export pci_flags

2012-03-20T17:41:33+00:00

There's no need to export pci_flags; it's not exported by any other
architecture, and no modules reference it.

arm/PCI: get rid of device resource fixups

2012-02-24T03:19:01+00:00

Tell the PCI core about host bridge address translation so it can take
care of bus-to-resource conversion for us.

arm/PCI: remove arch pci_flags definition

2012-02-24T03:18:56+00:00

The PCI core provides a pci_flags definition (currently __weak), so drop
the arm definition in favor of that.

We EXPORT_SYMBOL(pci_flags) as arm did previously.  I'm dubious about
this: no other architecture exports it, and I didn't see any modules in
the tree that reference it.

arm/PCI: convert to pci_scan_root_bus() for correct root bus resources

2012-01-06T20:10:56+00:00

Convert from pci_scan_bus() 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.
