2007-06-29[POWERPC] Remove hack to determine the 2nd PHBs bus numberKumar Gala
Now that we have the pci_controller in the exclude function we can easy figure out if the bus number is the PHB or not. The old style of using a variable setup at init time was actually broken and would only work in specific cases. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-06-29[POWERPC] Pass the pci_controller into pci_exclude_deviceKumar Gala
There are times that we need to know which controller we are on to decide how to exclude devices properly. We now pass the pci_controller that we are going to use down to the pci_exclude_device function. This will greatly simplify being able to exclude the PHBs in multiple controller setups.

2007-06-29[POWERPC] Remove set_cfg_type for PCI indirect users that don't need itKumar Gala
The Freescale and Marvell PCI controllers dont require explicit setting for type 1 config cycles. They handle producing them by implicitly looking at the bus, devfn. The TSI108 and 52xx don't use the generic PCI indirect code and thus don't bother with set_cfg_type. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-06-29[POWERPC] kill isa_{io,mem}_base definitions for !PCIArnd Bergmann
When CONFIG_PCI is disabled, the definitions for isa_io_base, isa_mem_base and pci_dram_offset are entirely unused, but they can result in link failure because they are defined in multiple places. The easiest fix is to just remove all these definitions. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2007-06-29[POWERPC] rename add_bridge to avoid namespace clashesArnd Bergmann
Many platforms currently define their own add_bridge function, some of them globally. This breaks some multiplatform configurations. Prefixing each of these functions with the platform name avoids this problem. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2007-05-07[POWERPC] Rename device_is_compatible to of_device_is_compatibleStephen Rothwell

2006-12-04[POWERPC] Remove ioremap64 and fixup_bigphys_addrBenjamin Herrenschmidt
In order to suppose platforms with devices above 4Gb on 32 bits platforms with a >32 bits physical address space, we used to have a special ioremap64 along with a fixup routine fixup_bigphys_addr. This shouldn't be necessary anymore as struct resource now supports 64 bits addresses even on 32 bits archs. This patch enables that option when CONFIG_PHYS_64BIT is set and removes ioremap64 and fixup_bigphys_addr. This is a preliminary work for the upcoming merge of 32 and 64 bits io.h Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-12-04[POWERPC] Make pci_read_irq_line the defaultBenjamin Herrenschmidt
This patch reworks the way IRQs are fixed up on PCI for arch powerpc. It makes pci_read_irq_line() called by default in the PCI code for devices that are probed, and add an optional per-device fixup in ppc_md for platforms that really need to correct what they obtain from pci_read_irq_line(). It also removes ppc_md.irq_bus_setup which was only used by pSeries and should not be needed anymore. I've also removed the pSeries s7a workaround as it can't work with the current interrupt code anyway. I'm trying to get one of these machines working so I can test a proper fix for that problem. I also haven't updated the old-style fixup code from 85xx_cds.c because it's actually buggy :) It assigns pci_dev->irq hard coded numbers which is no good with the new IRQ mapping code. It should at least use irq_create_mapping(NULL, hard_coded_number); and possibly also set_irq_type() to set them as level low.

2006-09-21POWERPC: overhaul with cpm2_map mechanismVitaly Bordug
Incorporating the new way of cpm2 immr access, introduced in the previous patch, into CPM2 peripheral devices (fs_enet and cpm_uart). Both ppc and powerpc approved working( real actions taken in powerpc only, ppc just has a wrapper to keep init stuff consistent). Signed-off-by: Vitaly Bordug <vbordug@ru.mvista.com>
2006-09-21POWERPC: Add support for the mpc8560 eval boardVitaly Bordug
This makes the 8560 evaluation board fully supported under arch/powerpc, as the first board with CPM2 SoC peripherals. The brand new devicetree nodes are introduced (intending to be a subset of the QuiccEngine-equipped models, with dts sources placed into the kernel according to the new convention. Assuming all the preceding stuff applied (PAL+fs_enet related+ CPM_UART update), the both TSEC eth ,FCC Eths, and both SCC UARTs are working. The relevant drivers are still capable to drive users in ppc, which was verified with 8272ADS (SCC uart+FCC eth). This is also verified on mpc8540 and actually make it work (PCI stuff working as well) Signed-off-by: Vitaly Bordug <vbordug@ru.mvista.com>

2006-03-30powerpc: converted embedded platforms to use new define_machine supportKumar Gala
Removed platform_init usage on 83xx and 85xx and use define_machine and probe(). For now we always return true in the problem since you can only build for one specific board at a time. This is an artificial constraint. When we get ride of it we will need to update the Kconfig's for these sub-arch's and make the board's probe() functions actually do something.

2005-10-11ppc: Various minor compile fixesPaul Mackerras
This fixes up a variety of minor problems in compiling with ARCH=ppc arising from using the merged versions of various header files. A lot of the changes are just adding #include <asm/machdep.h> to files that use ppc_md or smp_ops_t. This also arranges for us to use semaphore.c, vecemu.c, vector.S and fpu.S from arch/powerpc/kernel when compiling with ARCH=ppc. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-09-26powerpc: Merge enough to start building in arch/powerpc.Paul Mackerras
This creates the directory structure under arch/powerpc and a bunch of Kconfig files. It does a first-cut merge of arch/powerpc/mm, arch/powerpc/lib and arch/powerpc/platforms/powermac. This is enough to build a 32-bit powermac kernel with ARCH=powerpc. For now we are getting some unmerged files from arch/ppc/kernel and arch/ppc/syslib, or arch/ppc64/kernel. This makes some minor changes to files in those directories and files outside arch/powerpc. The boot directory is still not merged. That's going to be interesting.
