2012-05-13ARM: PCI: provide a default bus scan implementationRussell King
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.

2012-05-13ARM: PCI: get rid of pci_std_swizzle()Russell King
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.

CNS3xxx SOCs have L310-compatible cache controller, so let's use it. With this patch benchmarking with 'gzip' shows that performance is doubled, and I'm still able to boot full-fledged userland over NFS (using PCIe NIC), so the support should be pretty robust. p.s. While CNS3xxx reports that it has PL310, it still needs to wait on cache line operations, so we should not select 'CACHE_PL310', which is a micro-optimization that removes these waits for v7 CPUs. Someday we'd better rename CACHE_PL310 Kconfig option into NO_CACHE_WAIT or something less ambiguous. Signed-off-by: Anton Vorontsov <avorontsov@mvista.com>

2010-12-14ARM: GIC: private a standard get_irqnr_preamble assembler macroRussell King
Provide a standard get_irqnr_preamble assembler macro for platforms to use, which retrieves the base address of the GIC CPU interface from gic_cpu_base_addr. Allow platforms to override this by defining HAVE_GET_IRQNR_PREAMBLE.

2010-12-14ARM: GIC: consolidate gic_cpu_base_addr to common GIC codeRussell King
Every architecture using the GIC has a gic_cpu_base_addr pointer for GIC 0 for their entry assembly code to use to decode the cause of the current interrupt. Move this into the common GIC code.
