2007-08-03[POWERPC] Fix parse_drconf_memory() for 64-bit start addressesMichael Ellerman
Some new machines use the "ibm,dynamic-reconfiguration-memory" property to provide memory layout information, rather than via memory nodes. There is a bug in the code to parse this property for start addresses over 4GB; we store the start address in an unsigned int, which means we throw away the high bits and add apparently duplicate regions. This results in a BUG() in free_bootmem_core(). This fixes it by using an unsigned long instead.

2007-08-03[POWERPC] Fix num_cpus calculation in smp_call_function_map()Kevin Corry
In smp_call_function_map(), num_cpus is set to the number of online CPUs minus one. However, if the CPU mask does not include all CPUs (except the one we're running on), the routine will hang in the first while() loop until the 8 second timeout occurs. The num_cpus should be set to the number of CPUs specified in the mask passed into the routine, after we've made any modifications to the mask. With this change, we can also get rid of the call to cpus_empty() and avoid adding another pass through the bitmask.

2007-08-03[POWERPC] spufs: Fix affinity after introduction of node_allowed() callsAndre Detsch
This patch fixes affinity reference point placement, which was not being done in some situations, after the introduction of node_allowed() calls. The previously used parameter, 'ctx', is just the iterator of the previous list_for_each_entry_reverse loop, and its value might be invalid at the end of the loop. Also, the right context to seek for information when defining the reference ctx location _is_ the reference ctx.

2007-08-03[POWERPC] Fix special PTE code for secondary hash bucketPaul Mackerras
The code for mapping special 4k pages on kernels using a 64kB base page size was missing the code for doing the RPN (real page number) manipulation when inserting the hardware PTE in the secondary hash bucket. It needs the same code as has already been added to the code that inserts the HPTE in the primary hash bucket. This adds it. Spotted by Ben Herrenschmidt.

2007-07-26[POWERPC] spusched: Fix initial timeslice calculationChristoph Hellwig
Currently we calculate the first timeslice for every context incorrectly - alloc_spu_context calls spu_set_timeslice before we set ctx->prio so we always calculate the longest possible timeslice for the lowest possible priority. This patch makes sure to update the schedule-related fields before calculating the timeslice and also makes sure we update the timeslice for a non-running context when entering spu_run so a priority change affects the context as soon as possible.

This patch uses the newly added functions for testing if an address is an ISA or PCI IO port to properly unmap things in pci_iounmap that aren't such ports.

2007-07-26[POWERPC] Fix Pegasos keyboard detectionAlan Curry
As of 2.6.22 the kernel doesn't recognize the i8042 keyboard/mouse controller on the PegasosPPC. This is because of a feature/bug in the OF device tree: the "device_type" attribute is an empty string instead of "8042" as the kernel expects. This adds a secondary detection which looks for a device whose *name* is "8042" if there is no device whose *type* is "8042".

This reverts commit fd6e9d3945ee122eb513ada8b17296d243c1ce5e. Having #size-cells == 0 in a node indicates that things under the node aren't directly accessible, and therefore we shouldn't try to translate addresses for devices under the node into CPU physical addresses. Some drivers, such as the nvram driver for powermacs, rely on of_address_to_resource failing if they are called for a node representing a device whose resources aren't directly accessible by the CPU. These drivers were broken by commit fd6e9d39, resulting in the "Lombard" powerbook hanging early in the boot process. Signed-off-by: Paul Mackerras <paulus@samba.org>

2007-07-24[POWERPC] 85xxCDS: Delay 8259 cascade hookup.Randy Vinson
The interrupts of an E100 card inserted in PCI slot 4 may be on at bootup. The resulting interrupt flood interacts with the 8259 cascade handler and prevents proper boot up. There is a quirk for the E100 that will disable the E100's interrupts but to use it, the 8259 cascade hookup must be delayed until after the quirk has run. This patch delays the 8259 cascade hookup by registering a device_initcall() which runs after the PCI quirk for the E100.

2007-07-23[POWERPC] 85xxCDS: Make sure restart resets the PCI bus.Randy Vinson
The current 85xxCDS restart code fails to reset the PCI bus which can lead to odd behavior after the restart. This patch uses the VIA Super Southbridge to perform a PCI reset which will reset the entire system. NOTE: Since the VIA chip is behind a PCI-to-PCI bridge which can be disabled with a switch setting, it may not be possible to perform the PCI bus reset. In this case, the code defaults to the previous restart mechanism. Signed-off-by: Randy Vinson <rvinson@mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-07-23[POWERPC] 85xxCDS: Allow 8259 cascade to share an MPIC interrupt line.Randy Vinson
The Freescale MPC8555CDS and MPC8548CDS reference hardware has a legacy 8259 interrupt controller pair contained within a VIA VT82C686B Southbridge on the main carrier board. The processor complex plugs into the carrier card using a PCI slot which limits the available interrupts to the INTA-INTD PCI interrupts. The output of the 8259 cascade pair is routed through a gate array and connected to the PCI INTA interrupt line. The normal interrupt chaining hook (set_irq_chained_handler) does not allow sharing of the chained interrupt which prevents the use of PCI INTA by PCI devices. This patch allows the 8259 cascade pair to share their interrupt line with PCI devices. NOTE: The addition of the .end routine for the MPIC is not strictly necessary for this patch. It's there so this code will run from within the threaded interrupt context used by the Real Time patch.

2007-07-23[POWERPC] FSL: Add support for PCI-X controllersKumar Gala
Some set of 85xx platforms have PCI-X controllers. The old arch/ppc code setup these controllers and we haven't moved it over to arch/powerpc. We use the PCI-X Capabilties to know if we are in PCI-X mode instead of the Global Utilities PORDEVSR. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-07-23[POWERPC] Make sure virtual P2P bridge registers are setup on PCIe PHBKumar Gala
For the Freescale PCIe PHBs Not all firmwares setup the virtual P2P bridge registers properly. Make sure they get setup based on what the struct pci_controller got from the device tree. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-07-23[POWERPC] Provide ability to setup P2P bridge registers from struct resourceKumar Gala
We need the ability to set P2P bridge registers to properly setup the virtual P2P bridges that exist in PCIe controllers for some of the embedded setups. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-07-23[POWERPC] Add basic PCI/PCI Express support for 8544DS boardRoy Zang
Add basic support for the PCIe PHB and enable the ULI bridge. Signed-off-by: York Sun <yorksun@freescale.com> Signed-off-by: Roy Zang <tie-fei.zang@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-07-23[POWERPC] Make endianess of cfg_addr for indirect pci ops runtimeKumar Gala
Make it so we do a runtime check to know if we need to write cfg_addr as big or little endian. This is needed if we want to allow 86xx support to co-exist in the same kernel as other 6xx PPCs. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-07-23[POWERPC] Removed setup_indirect_pci_nomapKumar Gala
We don't use setup_indirect_pci_nomap in arch/powerpc and it appears the users that needed it from arch/ppc are now using setup_indirect_pci. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-07-23[POWERPC] 85xx: Add quirk to ignore bogus FPGA on CDSKumar Gala
The newer Arcadia boards for CDS have an FPGA that shows up on PCI however isn't a real PCI device. Add a quirk to just ignore the FPGA. This is based on the following patch from Andy & York: http://ozlabs.org/pipermail/linuxppc-dev/2007-February/032042.html Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-07-23[POWERPC] 85xx: Added 8568 PCIe supportKumar Gala
Added the PCIe device node to the 8568 dts and the needed quirk entries. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-07-23[POWERPC] Fixup resources on pci_bus for PCIe PHB when no device is connectedKumar Gala
On the 85xx/86xx PCIe controllers if there is no device connected to the PHB we will still allocate a pci_bus for downstream bus of the virtual P2P bridge. However the resources allocated to the downstream bus are not correct and so we just mimic the resources from the upstream pci_bus. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
