* [POWERPC] 86xx: mpc8610_hpcd: fix second serial portAnton Vorontsov2008-05-131-2/+12
| | | | | | | | | | | DIU platform code should not just write to the PIXIS' BRDCFG0 register, it should set and clear its own bits only, otherwise it will break firmware setup (in fact it breaks second uart). Also get rid of magic numbers in the related code. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* [POWERPC] 86xx: mpc86xx_hpcn - Temporarily accept old dts node identifier.Paul Gortmaker2008-04-171-0/+6
| | | | | | | | | | | | | As suggested by Timur Tabi, we match on the old compat node ID for one version and warn accordingly. If we don't do this, we plunge people who try to use an old DTB into silent boot death with no clear indication of what the problem is. This patch should be removed at the beginning of the 2.6.27 dev cycle. It is only meant to ease the transition in the short term.

| | | | | | | | | On the majority of 85xx & 86xx we have a register that's ability to assert HRESET_REQ to reset the board.

* [POWERPC] Fix interrupt routing and setup of ULI M1575 on FSL boardsKumar Gala2007-08-172-208/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The interrupt routing in the device trees for the ULI M1575 was inproperly using the interrupt line field as pci function. Fixed up the device tree's to actual conform for to specification and changed the interrupt mapping code so it just uses a static mapping setup as follows: PIRQA - IRQ9 PIRQB - IRQ10 PIRQC - IRQ11 PIRQD - IRQ12 USB 1.1 OCHI (1c.0) - IRQ12 USB 1.1 OCHI (1c.1) - IRQ9 USB 1.1 OCHI (1c.2) - IRQ10 USB 1.1 ECHI (1c.3) - IRQ11 LAN (1b.0) - IRQ6 AC97 (1d.0) - IRQ6 Modem (1d.1) - IRQ6 HD Audio (1d.2) - IRQ6 SATA (1f.1) - IRQ5 SMB (1e.1) - IRQ7 PMU (1e.2) - IRQ7 PATA (1f.0) - IRQ14/15 Took the oppurtunity to refactor the code into a single file so we don't have to duplicate these fixes on the two current boards in the tree and several forth coming boards that will also need the code. Fixed RTC support that requires a dummy memory read on the P2P bridge to unlock the RTC and setup the default of the RTC alarm registers to match with a basic x86 style CMOS RTC. Moved code that poked ISA registers to a FIXUP_FINAL quirk to ensure the PCI IO space has been setup properly before we start poking ISA registers at random locations.

* [POWERPC] Fixup resources on pci_bus for PCIe PHB when no device is connectedKumar Gala2007-07-231-1/+1
| | | | | | | | | On the 85xx/86xx PCIe controllers if there is no device connected to the PHB we will still allocate a pci_bus for downstream bus of the virtual P2P bridge. However the resources allocated to the downstream bus are not correct and so we just mimic the resources from the upstream pci_bus. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | | resources. The Freescale PCI-e RC poses as a transparent bridge, but does not implement the IO_BASE or IO_LIMIT registers in the config space. This means that the code which initializes the bridge resources ends up setting the IO resources erroneously. Add quick_fsl_pcie_transparent() to handle this. This change sets RC of mpc8641 to be a transparent bridge for legacy I/O access and initializes the RC bridge resources from the device tree.

* [POWERPC] 86xx: Workaround PCI_PRIMARY_BUS usageKumar Gala2007-06-291-1/+3
| | | | | | | | | | | | | | | The Freescale PCI-e controllers have an issue in that they use the PCI_PRIMARY_BUS register in the virtual P2P bridge to determine which bus number to match on when generating a type 0 config cycle. The issue is if we are renumbering bus numbers to match Linux we will try setting the PCI_PRIMARY_BUS and will not know which bus number to use for generating type 0 config cycles. We surpress writing the register in the P2P bridge and always keep it at zero. In the future when proper PCI domain support is working we should be able to remove this.

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] kill isa_{io,mem}_base definitions for !PCIArnd Bergmann2007-06-291-7/+0
| | | | | | | | | | | When CONFIG_PCI is disabled, the definitions for isa_io_base, isa_mem_base and pci_dram_offset are entirely unused, but they can result in link failure because they are defined in multiple places.

* [POWERPC] Make pci_read_irq_line the defaultBenjamin Herrenschmidt2006-12-041-10/+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.
