* [POWERPC] pci32: Add platform option to enable /proc PCI domainsBenjamin Herrenschmidt2007-12-20
| | | | | | | | This adds flags the platforms can use to enable domain numbers in /proc/bus/pci. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [POWERPC] Merge pci_process_bridge_OF_ranges()Benjamin Herrenschmidt2007-12-10
| | | | | | | | | | | | | | | | | | | This merges the 32-bit and 64-bit implementations of pci_process_bridge_OF_ranges(). The new function is cleaner than both the old ones, and supports 64 bits ranges on ppc32 which is necessary for the 4xx port. It also adds some better (hopefully) output to the kernel log which should help diagnose problems and makes better use of existing OF parsing helpers (avoiding a few bugs of both implementations along the way). There are still a few unfortunate ifdef's but there is no way around these for now at least not until some other bits of the PCI code are made common.

* [POWERPC] Make isa_mem_base common to 32 and 64 bitsBenjamin Herrenschmidt2007-12-10
| | | | | | | | | This defines isa_mem_base on both 32 and 64 bits (it used to be 32 bits only). This avoids a few ifdef's in later patches and potentially can allow support for VGA text mode on 64 bits powerpc.

* | [POWERPC] Add function to check if address is an IO portBenjamin Herrenschmidt2007-07-26
|/ | | | | | | | | This adds a function that tells you if a given kernel virtual address is hitting a PCI or ISA IO port permanent mapping or not. This is to be used in the next patch to fix iomap APIs to properly unmap things. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

* [POWERPC] Use ppc64 style list management for pci_controller on ppc32Kumar Gala2007-06-29
| | | | | | | | Use the ppc64 style list management and allocation functions for pci_controllers. This makes the pci_controller structs just a bit more common between ppc32 & ppc64. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* [POWERPC] Move common PCI code out of pci_32/pci_64Kumar Gala2007-06-29

* [POWERPC] Use global_number in ppc32 pci_controllerKumar Gala2007-06-29
Make the pci_controller struct use global_number for the PHB domain number instead of index to match what ppc64 does and reuse its pci_domain_nr code. Introduced a pci-common.c to handle shared code between ppc32 & ppc64. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
