Russell King c23bfc3835 ARM: PCI: provide a default bus scan implementation
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.

Russell King daeb4c0c3b ARM: PCI: get rid of pci_std_swizzle()
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.

Bjorn Helgaas 9f786d033d arm/PCI: get rid of device resource fixups
Tell the PCI core about host bridge address translation so it can take
care of bus-to-resource conversion for us.

Bjorn Helgaas 37d15909ff arm/PCI: convert to pci_scan_root_bus() for correct root bus resources
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.

Rob Herring c9d95fbe59 ARM: convert PCI defines to variables
Convert PCIBIOS_MIN_IO and PCIBIOS_MIN_MEM to variables to allow
multi-platform builds. This also removes the requirement for a platform to
have a mach/hardware.h.

The default values for i/o and mem are 0x1000 and 0x01000000, respectively.
Per Arnd Bergmann, other values are likely to be incorrect, but this commit
does not try to address that issue.

Andrew Victor 8e6c81fe28 [ARM] 5297/1: [KS8695] Fix two compile-time warnings
Fix two warnings when compiling for the KS8695 processor.

arch/arm/include/asm/dma-mapping.h: In function 'dma_to_virt':
arch/arm/include/asm/dma-mapping.h:40: warning: return makes pointer
from integer without a cast

Section mismatch in reference from the function pcibios_fixup_bus() to
the (unknown reference) .devinit.text:(unknown)
The function pcibios_fixup_bus() references
the (unknown reference) __devinit (unknown).
This is often because pcibios_fixup_bus lacks a __devinit
annotation or the annotation of (unknown) is wrong.
