* [POWERPC] Merge 32 and 64 bits asm-powerpc/io.hBenjamin Herrenschmidt2006-12-041-0/+1
| | | | | | | | | | | | | powerpc: Merge 32 and 64 bits asm-powerpc/io.h The rework on io.h done for the new hookable accessors made it easier, so I just finished the work and merged 32 and 64 bits io.h for arch/powerpc. arch/ppc still uses the old version in asm-ppc, there is just too much gunk in there that I really can't be bothered trying to cleanup.

* [POWERPC] Generic OF platform driver for PCI host bridges.Benjamin Herrenschmidt2006-12-041-3/+4
| | | | | | | | | | | | | | | | | When enabled in Kconfig, it will pick up any of_platform_device matching it's match list (currently type "pci", "pcix", "pcie", or "ht" and setup a PHB for it. Platform must provide a ppc_md.pci_setup_phb() for it to work (for doing the necessary initialisations specific to a given PHB like setting up the config space ops). It's currently only available on 64 bits as the 32 bits PCI code can't quite cope with it in it's current form. I will fix that later.

* [POWERPC] Resolve the BUID for RTAS PCI config space accessesBenjamin Herrenschmidt2006-12-041-23/+4
| | | | | | | | | | | The BUID is the first entry of a PCI host bridge "reg" property. Now that PCI busses can be anywhere in the device-tree, we need to fully translate the value there to a CPU physical address before we can use it with RTAS.

* [POWERPC] Add a helper for calculating RTAS "config_addr" parametersMichael Ellerman2006-08-251-4/+2
| | | | | | | | | | | | | Several RTAS calls take a "config_addr" parameter, which is a particular way of specifying a PCI busno, devfn and register number into a 32-bit word. Currently these are open-coded, and I'll be adding another soon, replace them with a helper that encapsulates the logic. Be more strict about masking the busno too, just in case. Booted on P5 LPAR.

* [POWERPC] Constify & voidify get_property()Jeremy Kerr2006-07-311-11/+11
| | | | | | | | | | | Now that get_property() returns a void *, there's no need to cast its return value. Also, treat the return value as const, so we can constify get_property later. powerpc core changes. Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [POWERPC] Add new interrupt mapping core and change platforms to use itBenjamin Herrenschmidt2006-07-031-17/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the new irq remapper core and removes the old one. Because there are some fundamental conflicts with the old code, like the value of NO_IRQ which I'm now setting to 0 (as per discussions with Linus), etc..., this commit also changes the relevant platform and driver code over to use the new remapper (so as not to cause difficulties later in bisecting). This patch removes the old pre-parsing of the open firmware interrupt tree along with all the bogus assumptions it made to try to renumber interrupts according to the platform. This is all to be handled by the new code now. For the pSeries XICS interrupt controller, a single remapper host is created for the whole machine regardless of how many interrupt presentation and source controllers are found, and it's set to match any device node that isn't a 8259. That works fine on pSeries and avoids having to deal with some of the complexities of split source controllers vs. presentation controllers in the pSeries device trees. The powerpc i8259 PIC driver now always requests the legacy interrupt range. It also has the feature of being able to match any device node (including NULL) if passed no device node as an input. That will help porting over platforms with broken device-trees like Pegasos who don't have a proper interrupt tree.

| * [PATCH] powerpc: properly configure DDR/P5IOC children devsJohn Rose2006-03-161-23/+1
| | | | | | | | | | | | | | | | | | | | | | The dynamic add path for PCI Host Bridges can fail to configure children adapters under P5IOC controllers. It fails to properly fixup bus/device resources, and it fails to properly enable EEH. Both of these steps need to occur before any children devices are enabled in pci_bus_add_devices().

* [PATCH] powerpc: Remove device_node addrs/n_addrBenjamin Herrenschmidt2006-01-091-37/+12
| | | | | | | | | | | | The pre-parsed addrs/n_addrs fields in struct device_node are finally gone. Remove the dodgy heuristics that did that parsing at boot and remove the fields themselves since we now have a good replacement with the new OF parsing code. This patch also fixes a bunch of drivers to use the new code instead, so that at least pmac32, pseries, iseries and g5 defconfigs build.

* [PATCH] powerpc: pci_64 fixes & cleanupsBenjamin Herrenschmidt2005-11-161-63/+5
| | | | | | | | | | | | | | | | I discovered that in some cases (PowerMac for example) we wouldn't properly map the PCI IO space on recent kernels. In addition, the code for initializing PCI host bridges was scattered all over the place with some duplication between platforms. This patch fixes the problem and does a small cleanup by creating a pcibios_alloc_controller() in pci_64.c that is similar to the one in pci_32.c (just takes an additional device node argument) that takes care of all the grunt allocation and initialisation work. It should work for both boot time and dynamically allocated PHBs. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [PATCH] powerpc: Move more ppc64 files with no ppc32 equivalent to powerpcDavid Gibson2005-11-101-0/+513
This patch moves a bunch more files from arch/ppc64 and include/asm-ppc64 which have no equivalents in ppc32 code into arch/powerpc and include/asm-powerpc. The file affected are: hvcall.h proc_ppc64.c sysfs.c lparcfg.c rtas_pci.c The only changes apart from the move and corresponding Makefile changes are: - #ifndef/#define in includes updated to _ASM_POWERPC_ form - trailing whitespace removed - comments giving full paths removed Built and booted on POWER5 LPAR (ARCH=powerpc and ARCH=ppc64), built for 32-bit powermac (ARCH=powerpc).
