2011-01-03powerpc/5200: dts: rename nodes to prepare for refactoring dts filesJohn Bonesio9-26/+26
This patch renames nodes in dts fils for MPC5200b files to prepare for refactoring of these files later. When refactoring it will be easier to verify the results if the node names aren't changing at the same time.

2011-01-01of/flattree: Add of_flat_dt_match() helper functionGrant Likely9-76/+51
This patch adds of_flat_dt_match() which tests a node for compatibility with a list of values and converts the relevant powerpc platform code to use it.

2010-12-29of/flattree: Add Kconfig for EARLY_FLATTREEStephen Neuendorffer1-1/+1
The device tree code is now in two pieces: some which can be used generically on any platform which selects CONFIG_OF_FLATTREE, and some early which is used at boot time on only a few architectures. This patch segregates the early code so that only those architectures which care about it need compile it. This also means that some of the requirements in the early code (such as a cmd_line variable) that most architectures (e.g. X86) don't provide can be ignored.

This patch changes u32 to __be32 for all "ranges", "prop" and "addr" and such. Those variables are pointing to the device tree which contains integers in big endian format. Most functions are doing it right because of_read_number() is doing the right thing for them. of_bus_isa_get_flags(), of_bus_pci_get_flags() and of_bus_isa_map() were accessing the data directly and were doing it wrong.

2010-12-09powerpc/powermac: Make auto-loading of therm_pm72 possibleMarc Zyngier1-0/+9
The therm_pm72 driver, used on the PowerMac G5 range, cannot be auto-loaded, since the driver itself creates both the device node and the driver instance. Moving the device node creation to the platform setup code and adding the necessary MODULE_DEVICE_TABLE() information allows the driver to be automatically loaded by udev on any semi-modern distribution. It "fixes" a major source of problem on G5 machines where the driver wasn't explicitely loaded by default, and the system would automatically shutdown under load. Tested on an Xserve G5.

2010-12-09powerpc: Disable VPHN polling during a suspend operationJesse Larrew2-0/+13
Tie the polling mechanism into the ibm,suspend-me rtas call to stop/restart polling before/after a suspend, hibernate, migrate, or checkpoint restart operation. This ensures that the system has a chance to disable the polling if the partition is migrated to a system that does not support VPHN (and vice versa).

2010-12-09powerpc/pseries: Poll VPA for topology changes and update NUMA mapsJesse Larrew2-11/+271
This patch sets a timer during boot that will periodically poll the associativity change counters in the VPA. When a change in associativity is detected, it retrieves the new associativity domain information via the H_HOME_NODE_ASSOCIATIVITY hcall and updates the NUMA node maps and sysfs entries accordingly. Note that since the ibm,associativity device tree property does not exist on configurations with both NUMA and SPLPAR enabled, no device tree updates are necessary.

2010-12-09powerpc: Record vma->phys_addr in ioremap()Michael Ellerman2-0/+3
The vmalloc code can track the physical address of a vma, when the vma is used for ioremap, if set it is displayed in /proc/vmallocinfo. Because get_vm_area_caller() doesn't know it's being called for ioremap() it's up to the arch code to set the phys_addr. A bunch of other arch's do this, I'm not sure why powerpc doesn't?

2010-12-09powerpc/pseries: Pass phb only to iommu_table_setparms_lparBenjamin Herrenschmidt1-7/+4
iommu_table_setparms_lpar needs either the phb or the subbusnumber (not both), pass the phb to make it similar to iommu_table_setparms. Note: In cases where a caller was passing bus->number previously to iommu_table_setparms_lpar() rather than phb->bus->number, this can lead to a different value in tbl->it_busno. The only example of this was the removed pci_dma_dev_setup_pSeriesLP(), removed in "ppc/iommu: remove unneeded pci_dma_dev_setup_pSeriesLP". [BenH: You updated only one of the two callers.

2010-12-09powerpc/pseries: Do not need to check for dma_window == NULLNishanth Aravamudan1-6/+0
The block in pci_dma_dev_setup_pSeriesLP for dma_window == NULL can be removed because we will only teminate the loop if we had already allocated a iommu table for that node or we found a window. While there may be no window for the device, the intresting part is if we are reusing a table or creating it for the first device under it.

2010-12-09powerpc/pseries: Checking for pdn->parent is redundantNishanth Aravamudan1-4/+1
The device tree root is never a pci bus, and will not have a PCI_DN(pdn), so the check for PCI_DN added in 650f7b3b2f0ead0673e90452cf3dedde97c537ba makes the check for pdn->parent redundant and it can be removed.

2010-12-09powerpc/pseries: Do not search for dma-window property on dlpar removeNishanth Aravamudan1-5/+1
The iommu_table pointer in the pci auxiliary struct of device_node has not been used by the iommu ops since the dma refactor of 12d04eef927bf61328af2c7cbe756c96f98ac3bf, however this code still uses it to find tables for dlpar. By only setting the PCI_DN iommu_table pointer on nodes with dma window properties, we will be able to quickly find the node for later checks, and can remove the table without looking for the the dma window property on dlpar remove.

The IOMMU code has been passing the dma-mask instead of the coherent_dma_mask to the iommu allocator. Coherent allocations should be made using the coherent_dma_mask. Also update the vio code to ensure the coherent_dma_mask is set. Without this change drivers, such as ibmvscsi, fail to load with the corrected dma_iommu_alloc_coherent().

2010-11-30powerpc/nvram: Move the log partition stuff to pseriesBenjamin Herrenschmidt3-237/+227
The nvram log partition stuff currently in nvram_64.c is really pseries specific. It isn't actually used on anything else (despite the fact that we ran the code to setup the partition on anything except powermac) and the log format is specific to pseries RTAS implementation.

Existing code is nasty, has bugs etc... rewrite the function more simply, and make it take the signature and optional name of the partitions to remove as arguments, thus making it a more generic utility.

2010-11-30powerpc/nvram: Shuffle code around in nvram_create_partition()Benjamin Herrenschmidt1-46/+62
This error log stuff is really pseries specific. As a first step we move the initialization of these variables to the caller of nvram_create_partition(), which is also slightly reorganized so we setup the free partition before we clear the new partition, so the chance of an error during clear leaving us with invalid headers is lessened.
