2008-01-23[POWERPC] 85xx: convert boards to use machine_device_initcallKumar Gala
Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2008-01-23[POWERPC] Fixup use of phys_addr_t in mpic codeBecky Bruce
The mpic_map() and __mpic_map_mmio() need to use phys_addr_t for the physical address they are passed. Signed-off-by: Becky Bruce <becky.bruce@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2008-01-23[POWERPC] Remove update_bridge_resourceKumar Gala
The 85xx/86xx pci code no longer uses update_bridge_resource and it was the only caller. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2008-01-23[POWERPC] FSL: Rework PCI/PCIe support for 85xx/86xxKumar Gala
The current PCI code for Freescale 85xx/86xx was treating the virtual P2P PCIe bridge as a transparent bridge. Rather than doing that fixup the virtual P2P bridge by copying the resources from the PHB. Also, fixup a bit of the code for dealing with resource_size_t being 64-bits and how we set ATMU registers for >4G. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2008-01-23[POWERPC] Fixup transparent P2P resourcesKumar Gala
For transparent P2P bridges the first 3 resources may get set from based on BAR registers and need to get fixed up. Where as the remainder come from the parent bus and have already been fixed up. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2008-01-23[POWERPC] Ensure we only handle PowerMac PCI bus fixup for memory resourcesKumar Gala
The fixup code that handles the case for PowerMac's that leave bridge windows open over an inaccessible region should only be applied to memory resources (IORESOURCE_MEM). If not we can get it trying to fixup IORESOURCE_IO on some systems since the other conditions that are used to detect the case can easily match for IORESOURCE_IO. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2008-01-23[POWERPC] Fix handling of memreserve if the range lands in highmemKumar Gala
There were several issues if a memreserve range existed and happened to be in highmem: * The bootmem allocator is only aware of lowmem so calling reserve_bootmem with a highmem address would cause a BUG_ON * All highmem pages were provided to the buddy allocator Added a lmb_is_reserved() api that we now use to determine if a highem page should continue to be PageReserved or provided to the buddy allocator. Also, we incorrectly reported the amount of pages reserved since all highmem pages are initally marked reserved and we clear the PageReserved flag as we "free" up the highmem pages.

2008-01-17[POWERPC] Add hugepagesz boot-time parameterJon Tollefson
This adds the hugepagesz boot-time parameter for ppc64. It lets one pick the size for huge pages. The choices available are 64K and 16M when the base page size is 4k. It defaults to 16M (previously the only only choice) if nothing or an invalid choice is specified. Tested 64K huge pages successfully with the libhugetlbfs 1.2.

2008-01-17[POWERPC] iSeries: eliminate pci_dn bussubnoStephen Rothwell
xlate_iomm_address() really wants the ds_addr to pass to the HV, so store that value (instead of the BAR number) when we allocate the device bars. This is not a fast path, so we can look up the device_node property there instead of using the bussubno field of the pci_dn. The other user of iseries_ds_addr() was already scanning the device tree, so looking up a property will not slow it down any more.

2008-01-17[POWERPC] Add of_find_matching_node() helper functionGrant Likely
Similar to of_find_compatible_node(), of_find_matching_node() and for_each_matching_node() allow you to iterate over the device tree looking for specific nodes, except that they take of_device_id tables instead of strings. This also moves of_match_node() from driver/of/device.c to driver/of/base.c to colocate it with the of_find_matching_node which depends on it.

2008-01-08[POWERPC] 4xx: PCIe: Increase max busses per port to 64Stefan Roese
Because of how big mapping the config space is (1M per bus), we limit how many busses we support for now. In the long run, we could replace that with something akin to kmap_atomic instead.

2007-12-28[POWERPC] pasemi: Distribute interrupts evenly across cpusOlof Johansson
By default the OpenPIC on PWRficient will bias to one core (since that will improve changes of the other core being able to stay idle/powered down). However, this conflicts with most irq load balancing schemes, since setting an interrupt to be delivered to either core doesn't really result in the load being shared. It also doesn't work well with the soft irq disable feature of PPC, since EE will stay on until the first interrupt is taken while soft disabled. Set the gconf0 config bit that enables even distribution of interrupts among the two cores. Signed-off-by: Olof Johansson <olof@lixom.net>
2007-12-28[POWERPC] pasemi: Implement NMI supportOlof Johansson
Some PWRficient-based boards have a NMI button that's wired up to a GPIO as interrupt source. By configuring the openpic accordingly, these get delivered as a machine check with high priority, instead of as an external interrupt. The device tree contains a property "nmi-source" in the openpic node for these systems, and it's the (hwirq) source for the input. Also, for these interrupts, the IACK is read from another register than the regular (MCACK instead), but they are EOI'd as usual. So implement said function for the mpic driver. Finally, move a couple of external function defines to include/ instead of local under sysdev. Being able to mask/unmask and eoi directly saves us from setting up a dummy irq handler that will never be called. Signed-off-by: Olof Johansson <olof@lixom.net>
