2009-07-03MIPS: Reorganize Cavium OCTEON PCI support.David Daney4-0/+2337
Move the cavium PCI files to the arch/mips/pci directory. Also cleanup comment formatting and code layout. Code from pci-common.c, was moved into other files. Signed-off-by: David Daney <ddaney@caviumnetworks.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2009-06-24MIPS: Build fix - include <linux/smp.h> into all smp_processor_id() users.Ralf Baechle1-0/+1
Some of the were relying into smp.h being dragged in by another header which of course is fragile. <asm/cpu-info.h> uses smp_processor_id() only in macros and including smp.h there leads to an include loop, so don't change cpu-info.h. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-01-30MIPS: RC32434: Define io_map_base for PCI controllerPhil Sutter1-0/+11
The code is rather based on trial-and-error than knowledge. Verified Via Rhine functionality in PIO as well as MMIO mode. [Looks sane -- Ralf] Signed-off-by: Phil Sutter <n0-1@freewrt.org> Tested-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-01-07PCI: mips: use generic INTx swizzle from PCI coreBjorn Helgaas1-16/+1
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 mips common_swizzle() did. I think they are equivalent for this purpose. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

2008-12-09MIPS: Better than nothing implementation of PCI mmap to fix X.Ralf Baechle1-0/+24
Certain X11 servers such as the SIS server will only work if PCI mmap is implemented. This patch implements PCI mmap but to be on the same side so close to a release it only supports uncached mappings so performance will not be optimal for some uses such as framebuffers. Thanks to Zhang Le <r0bertz@gentoo.org> for the original report and testing. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
