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] 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.

2008-01-15[POWERPC] Fix boot failure on POWER6Paul Mackerras
Commit 473980a99316c0e788bca50996375a2815124ce1 added a call to clear the SLB shadow buffer before registering it. Unfortunately this means that we clear out the entries that slb_initialize has previously set in there. On POWER6, the hypervisor uses the SLB shadow buffer when doing partition switches, and that means that after the next partition switch, each non-boot CPU has no SLB entries to map the kernel text and data, which causes it to crash. This fixes it by reverting most of 473980a9 and instead clearing the 3rd entry explicitly in slb_initialize. This fixes the problem that 473980a9 was trying to solve, but without breaking POWER6.

2008-01-15[POWERPC] Workaround for iommu page alignmentBenjamin Herrenschmidt
Commit 5d2efba64b231a1733c4048d1708d77e07f26426 changed our iommu code so that it always uses an iommu page size of 4kB. That means with our current code, drivers may do a dma_map_sg() of a 64kB page and obtain a dma_addr_t that is only 4k aligned. This works fine in most cases except for some infiniband HW it seems, where they tell the HW about the page size and it ignores the low bits of the DMA address. This works around it by making our IOMMU code enforce a PAGE_SIZE alignment for mappings of objects that are page aligned in the first place and whose size is larger or equal to a page.

2008-01-11[POWERPC] Fix CPU hotplug when using the SLB shadow bufferMichael Neuling
Before we register the SLB shadow buffer, we need to invalidate the entries in the buffer, otherwise we can end up stale entries from when we previously offlined the CPU. This does this invalidate as well as unregistering the buffer with PHYP before we offline the cpu. Tested and fixes crashes seen on 970MP (thanks to tonyb) and POWER5.

2008-01-10[POWERPC] efika: add phy-handle property for fec_mpc52xxOlaf Hering

But only the phy stuff is required to get a working network.

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>
