alpha/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.

alpha/PCI: replace pci_probe_only with pci_flags

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

Some architectures (alpha, mips, powerpc) have an arch-specific
"pci_probe_only" flag.  Others use PCI_PROBE_ONLY in pci_flags for
the same purpose.  This moves alpha to the pci_flags approach so
generic code can use the same test across all architectures.

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

2012-01-06T20:10:55+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.

v2: fix up conversion

alpha: switch to GENERIC_PCI_IOMAP

2011-11-28T19:13:01+00:00

alpha copied pci_iomap from generic code to avoid
pulling the rest of iomap.c in.  Since that's in
a separate file now, we can reuse the common implementation.

The only difference is handling of nocache flag,
that turns out to be done correctly by the
generic code since arch/alpha/include/asm/io.h
defines ioremap_nocache same as ioremap.

resource/PCI: mark struct resource as const

2010-02-23T00:16:57+00:00

Now that we return the new resource start position, there is no
need to update "struct resource" inside the align function.
Therefore, mark the struct resource as const.

resource/PCI: align functions now return start of resource

2010-02-23T00:16:56+00:00

As suggested by Linus, align functions should return the start
of a resource, not void. An update of "res->start" is no longer
necessary.

alpha: convert u64 to unsigned long long

2009-04-01T15:59:16+00:00

Convert alpha architecture to use u64 as unsigned long long.  This is
being done so that (a) all arches use u64 as unsigned long long and (b)
printk of a u64 as %ll[ux] will not generate format warnings by gcc.

The only gcc cross-compiler that I have is 4.0.2, which generates errors
about miscompiling __weak references, so I have commented out that line in
compiler-gcc4.h so that most of these compile, but more builds and real
machine testing would be Real Good.

PCI: alpha: use generic INTx swizzle from PCI core

2009-01-07T19:13:13+00:00

Use the generic pci_common_swizzle() instead of arch-specific code.

Note that pci_common_swizzle() loops based on dev->bus->self, not
dev->bus->parent as the alpha common_swizzle() did.  I think they
are equivalent for this purpose.
