2008-01-18[POWERPC] mpc5200: Add generic support for simple MPC5200 based boardsMarian Balakowicz
This patch adds support for 'mpc5200-simple-platform' compatible boards which do not need a platform specific setup. Such boards are supported assuming the following: - GPIO pins are configured by the firmware, - CDM configuration (clocking) is setup correctly by firmware, - if the 'fsl,has-wdt' property is present in one of the gpt nodes, then it is safe to use such gpt to reset the board, - PCI is supported if enabled in the kernel configuration and if there is a PCI bus node defined in the device tree.

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.

2008-01-09[POWERPC] Xilinx: Update booting-without-of.Stephen Neuendorffer
This now better describes what the UBoot device tree generator actually does. In particular: 1) Nodes have a label derived from the device name, and a node name derived from a generic version of the device type, e.g. 'ethernet', 'serial', etc. 2) Usage of compound nodes (representing more than one device in the same IP) which actually works. This requires having a valid compatible node, and all the other things that a bus normally has. I've chosen 'xlnx,compound' as the bus name to describe these compound nodes. In addition, I've clarified some of the language relating to how mhs nodes should be represent in the device tree.

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>
