[POWERPC] Platforms shouldn't mess with ROOT_DEV

2007-10-11T10:40:43Z

There is no good reason for board platform code to mess with the ROOT_DEV. Remove it from all in-tree platforms except powermac. Signed-off-by: Grant Likely Signed-off-by: Paul Mackerras

[POWERPC] cell: Add Cell memory controller register defs and expose it

2007-10-09T11:01:56Z

This adds definitions for the Cell memory controller registers (at least some of them) for use by the EDAC driver for ECC error reporting. It also expose the said MIC as a platform device that can be used by the EDAC driver to match on. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras

[POWERPC] cell: Move cbe_regs.h to include/asm-powerpc/cell-regs.h

2007-10-09T11:01:56Z

The new Cell EDAC driver needs that file, oprofile also does ugly path tricks to get to it, it's time to move it to asm-powerpc. While at it, rename it to be consistent with cell-pmu.h (and dashes look nicer than underscores anyway). Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras

[POWERPC] Rename device_is_compatible to of_device_is_compatible

2007-05-07T10:31:14Z

for consistency with other Open Firmware interfaces (and Sparc). This is just a straight replacement. This leaves the compatibility define in place. Signed-off-by: Stephen Rothwell Signed-off-by: Paul Mackerras

[POWERPC] Generic check_legacy_ioport

2007-04-27T11:14:30Z

check_legacy_ioport makes only sense on PREP, CHRP and pSeries. They may have an isa node with PS/2, parport, floppy and serial ports. Remove the check_legacy_ioport call from ppc_md, it's not needed anymore. Hardware capabilities come from the device-tree. Signed-off-by: Olaf Hering Signed-off-by: Paul Mackerras

[POWERPC] cell: abstract spu management routines

2006-12-04T09:40:39Z

This adds a platform specific spu management abstraction and the coresponding routines to support the IBM Cell Blade. It also removes the hypervisor only resources that were included in struct spu. Three new platform specific routines are introduced, spu_enumerate_spus(), spu_create_spu() and spu_destroy_spu(). The underlying design uses a new type, struct spu_management_ops, to hold function pointers that the platform setup code is expected to initialize to instances appropriate to that platform. For the IBM Cell Blade support, I put the hypervisor only resources that were in struct spu into a platform specific data structure struct spu_pdata.

[POWERPC] Cell iommu support

2006-12-04T09:39:02Z

This patch adds full cell iommu support (and iommu disabled mode). It implements mapping/unmapping of iommu pages on demand using the standard powerpc iommu framework. It also supports running with iommu disabled for machines with less than 2GB of memory. (The default is off in that case, though it can be forced on with the kernel command line option iommu=force).

[POWERPC] Generic OF platform driver for PCI host bridges.

2006-12-04T09:38:49Z

When enabled in Kconfig, it will pick up any of_platform_device matching it's match list (currently type "pci", "pcix", "pcie", or "ht" and setup a PHB for it. Platform must provide a ppc_md.pci_setup_phb() for it to work (for doing the necessary initialisations specific to a given PHB like setting up the config space ops). It's currently only available on 64 bits as the 32 bits PCI code can't quite cope with it in it's current form. I will fix that later.

[POWERPC] Add DMA ops support for of_platform_device to Cell

2006-12-04T09:38:42Z

This patch adds a bus device notifier to the of_platform bus type on cell to setup the DMA operations for of_platform_devices. We currently use the PCI operations as Cell use a special version of them that happens to be suitable for our needs. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras
