* powerpc: Move mpc83xx_add_bridge to fsl_pci.cJohn Rigby2008-07-161-91/+0
| | | | | | | | This allows other platforms with the same pci block like MPC5121 to use it. Signed-off-by: John Rigby <jrigby@freescale.com> Acked-by: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* [POWERPC] pci32: Add flags modifying the PCI code behaviourBenjamin Herrenschmidt2007-12-201-1/+1
| | | | | | | | | | | | | | This adds to the 32 bits PCI code some flags, replacing the old pci_assign_all_busses global, that allow us to control various aspects of the PCI probing, such as whether to re-assign all resources or not, or to not try to assign anything at all. This also adds the flag x86 already has to avoid ISA alignment on bridges that don't have ISA forwarding enabled (no legacy devices on the top level bus) and sets it for PowerMacs.

* [POWERPC] 83xx: Removed PCI exclude of PHBKumar Gala2007-09-141-7/+0
| | | | | | | Now that the generic code doesn't assign resources for Freescale PHBs we dont have to explicitly exclude it. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* [POWERPC] Make endianess of cfg_addr for indirect pci ops runtimeKumar Gala2007-07-231-2/+2
| | | | | | | | Make it so we do a runtime check to know if we need to write cfg_addr as big or little endian. This is needed if we want to allow 86xx support to co-exist in the same kernel as other 6xx PPCs. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* [POWERPC] Merge ppc32 and ppc64 pcibios_alloc_controller() prototypesKumar Gala2007-06-291-2/+1
| | | | | | | Make the ppc32 pcibios_alloc_controller take a device node to match the ppc64 prototypes and have it set arch_data. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* [POWERPC] Removed remnants of bus_offsetKumar Gala2007-06-291-1/+1
| | | | | | | | | | | Removed the remants of bus_offset and use self_busno in the mv64x60 case and use pci_assign_all_buses on 83xx/85xx. 83xx/85xx have multiple PHBs and the firmwares on these devices tend not to handle topologies with P2P bridges well so we let Linux just reassign the bus numbers to match. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* [POWERPC] Remove hack to determine the 2nd PHBs bus numberKumar Gala2007-06-291-7/+1
| | | | | | | | | Now that we have the pci_controller in the exclude function we can easy figure out if the bus number is the PHB or not. The old style of using a variable setup at init time was actually broken and would only work in specific cases. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* [POWERPC] Pass the pci_controller into pci_exclude_deviceKumar Gala2007-06-291-1/+1
| | | | | | | | | | There are times that we need to know which controller we are on to decide how to exclude devices properly. We now pass the pci_controller that we are going to use down to the pci_exclude_device function. This will greatly simplify being able to exclude the PHBs in multiple controller setups.

* [POWERPC] Remove set_cfg_type for PCI indirect users that don't need itKumar Gala2007-06-291-1/+0
| | | | | | | | | | | The Freescale and Marvell PCI controllers dont require explicit setting for type 1 config cycles. They handle producing them by implicitly looking at the bus, devfn. The TSI108 and 52xx don't use the generic PCI indirect code and thus don't bother with set_cfg_type. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* [POWERPC] rename add_bridge to avoid namespace clashesArnd Bergmann2007-06-291-1/+1
| | | | | | | | | Many platforms currently define their own add_bridge function, some of them globally. This breaks some multiplatform configurations. Prefixing each of these functions with the platform name avoids this problem. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

* [POWERPC] Make pci_read_irq_line the defaultBenjamin Herrenschmidt2006-12-041-9/+0
| | | | | | | | | | | | | | | | | | | | | | | | | This patch reworks the way IRQs are fixed up on PCI for arch powerpc. It makes pci_read_irq_line() called by default in the PCI code for devices that are probed, and add an optional per-device fixup in ppc_md for platforms that really need to correct what they obtain from pci_read_irq_line(). It also removes ppc_md.irq_bus_setup which was only used by pSeries and should not be needed anymore. I've also removed the pSeries s7a workaround as it can't work with the current interrupt code anyway. I'm trying to get one of these machines working so I can test a proper fix for that problem. I also haven't updated the old-style fixup code from 85xx_cds.c because it's actually buggy :) It assigns pci_dev->irq hard coded numbers which is no good with the new IRQ mapping code. It should at least use irq_create_mapping(NULL, hard_coded_number); and possibly also set_irq_type() to set them as level low.

| * [POWERPC] modify mpc83xx platforms to use new IRQ layerKim Phillips2006-08-301-0/+9
| | | | | | | | | | | | | | | | | | | | This fixes MPC834x MDS (formerly SYS) and ITX platform code to get IRQ data (including PCI) from the device tree, and to use the new IPIC code. renamed defconfig (sys -> mds), left one redundant NULL assignment in mpc83xx_pcibios_fixup to keep the compiler happy.
