* [POWERPC] Make isa_mem_base common to 32 and 64 bitsBenjamin Herrenschmidt2007-12-111-0/+3
| | | | | | | | | 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 Herrenschmidt2007-07-261-0/+23
|/ | | | | | | | | 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 Gala2007-06-291-0/+78
| | | | | | | | 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 Gala2007-06-291-0/+314
| | | | | | | Moved the low hanging fruit that was either identical or close to it between ppc32 & ppc64 for PCI into pci-common.c Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* [POWERPC] Use global_number in ppc32 pci_controllerKumar Gala2007-06-291-0/+53
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>
