[POWERPC] Maple: use mmio nvram

2007-02-07T03:03:23Z

Some systems supported by the maple platform (e.g. JS2x blades running SLOF) are able to use the mmio_nvram backend for reading and writing nvram. This is an improvement over the current situation -- no nvram access from userspace at all. Select MMIO_NVRAM for the maple platform. Initialize the mmio_nvram backend from maple setup code.

[POWERPC] Maple: don't override bus-range supplied by firmware

2007-02-07T03:03:17Z

This workaround was copy-pasted from the powermac code. It's not necessary for maple. Signed-off-by: Nathan Lynch Signed-off-by: Paul Mackerras

[POWERPC] maple: improve CPC9x5 host bridge detection

2007-01-24T10:13:58Z

Identify CPC9x5 PCI Express, AGP, and HT host bridges using device_type and compatible properties, which is a more flexible method than using the name property (which can differ between firmwares and models). Signed-off-by: Nathan Lynch Signed-off-by: Paul Mackerras

[POWERPC] Fix unbalanced uses of of_node_put

2007-01-09T06:03:01Z

The (maple|pasemi)_init_IRQ functions call of_node_put(root) once more than they should, causing the refcount of the root node to underflow, which triggers the WARN_ON in kref_get. Signed-off-by: Nathan Lynch Acked-by: Olof Johansson Signed-off-by: Paul Mackerras

[POWERPC] maple: Use RTAS for reboot and halt

2006-12-08T06:10:22Z

On maple, use the RTAS "system-reboot" and "power-off" methods if they are available. Signed-off-by: Nathan Lynch Signed-off-by: Paul Mackerras

[POWERPC] maple: Match "pcie" name for CPC945

2006-12-08T06:10:22Z

Some firmwares have "pcie" for the "name" property of the CPC945 PCI Express host bridge. Check for "pcie" in addition to "pci" so we don't miss it. Signed-off-by: Nathan Lynch Signed-off-by: Paul Mackerras

[POWERPC] Make pci_read_irq_line the default

2006-12-04T05:00:04Z

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. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras

[POWERPC] Fix Maple secondary IDE interrupt

2006-10-10T01:54:26Z

The IDE driver will pick up the PCI IRQ for both channels on Maple despite the fact that it's in legacy mode. This works around it by "hiding" the PCI IRQ of the AMD8111 IDE controller when it's configured in legacy mode on the Maple platform, thus causing the driver to call pci_get_legacy_ide_irq() which will return the correct interrupts for both channels.

[POWERPC] Make U4 PCIe work on maple

2006-10-10T01:54:26Z

The Maple support code was missing code for U4/CPC945 PCIe. This adds it, enabling it to work on tigerwood boards, and possibly also js21 using SLOF. Also disable an obsolete firmware workaround. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras
