2007-10-04[POWERPC] mpc82xx: Add pq2fads board support.Scott Wood3-0/+210
Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-10-04[POWERPC] mpc82xx: Update mpc8272ads, and factor out PCI and reset.Scott Wood7-550/+424
1. PCI and reset are factored out into pq2.c. I renamed them from m82xx to pq2 because they won't work on the Integrated Host Processor line of 82xx chips (i.e. 8240, 8245, and such). 2. The PCI PIC, which is nominally board-specific, is used on multiple boards, and thus is used into pq2ads-pci-pic.c. 3. The new CPM binding is used. 4. General cleanup.

2007-10-04[POWERPC] mpc82xx: Rename mpc82xx_ads to mpc8272_ads.Scott Wood3-5/+5
This is just a rename patch; internal references to mpc82xx_ads will be changed in the next one. Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-10-04[POWERPC] mpc82xx: Remove a bunch of cruft that duplicates generic functionality.Scott Wood4-125/+2
m82xx_calibrate_decr(), mpc82xx_ads_show_cpuinfo(), and mpc82xx_halt() do anything useful beyond what the generic code does. Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-09-14[POWERPC] Provide a default irq_host match, which matches on an exact of_nodeMichael Ellerman1-6/+0
The most common match semantic is an exact match based on the device node. So provide a default implementation that does this, and hook it up if no match routine is specified. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-09-14[POWERPC] Add an optional device_node pointer to the irq_hostMichael Ellerman1-5/+2
The majority of irq_host implementations (3 out of 4) are associated with a device_node, and need to stash it somewhere. Rather than having it somewhere different for each host, add an optional device_node pointer to the irq_host structure.

2007-08-22[POWERPC] Remove old includes from arch/ppcKumar Gala4-5/+0
Remove includes of files that existed in arch/ppc that we dont need in arch/powerpc anymore. The following includes were removed: <asm/amigappc.h> <asm/bootinfo.h> <asm/ppcboot.h> <asm/ppc_sys.h> <asm/residual.h> <asm/m8260_pci.h> This also caused platforms/embedded6xx/mpc7448_hpc2.h to no longer be needed and thus removed. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-07-23[POWERPC] Make endianess of cfg_addr for indirect pci ops runtimeKumar Gala1-1/+2
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>
2007-06-29[POWERPC] Merge ppc32 and ppc64 pcibios_alloc_controller() prototypesKumar Gala1-3/+1
Make the ppc32 pcibios_alloc_controller take a device node to match the ppc64 prototypes and have it set arch_data. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-06-29[POWERPC] Remove bus_offset in places its not really usedKumar Gala1-1/+0
The user of the fsl_pcie code doesn't set bus_offset and 82xx doesn't require it either. Remove the places in the code that reference it so we can remove it all together. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-06-29[POWERPC] Pass the pci_controller into pci_exclude_deviceKumar Gala1-1/+2
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. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-06-29[POWERPC] Remove set_cfg_type for PCI indirect users that don't need itKumar Gala1-3/+0
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] rename add_bridge to avoid namespace clashesArnd Bergmann1-2/+2
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>
2007-06-29[POWERPC] move 82xx/83xx/86xx Kconfig options to platform selectionArnd Bergmann1-1/+1
The cores used in the MPC82xx/83xx/86xx embedded controllers are very similar to those in the 32 bit general-purpose processors, so it makes sense to treat them as the same CPU family. Choosing between the embedded platforms and the multiplatform code is now done in the platform menu, but functionally everything stays the same. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2007-04-24Merge branch 'kconfig' of master.kernel.org:/pub/scm/linux/kernel/git/galak/powerpc into for-2.6.22Paul Mackerras1-35/+15
2007-04-12[POWERPC] Convert 82xx platform to unified platform KconfigKumar Gala1-35/+15
Moved 82xx platform Kconfig over to being sourced by the unified arch/powerpc/platforms/Kconfig. Also, cleaned up whitespace issues in 82xx Kconfig. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2007-03-22[POWERPC] Removed config options that we don't support in embedded6xxKumar Gala1-0/+35
When we started arch/powerpc we duplicated a number of config options from arch/ppc for various platforms that are supported. Now that we actually support a few platforms, remove all the ones that haven't been moved over. Additionally, this cleanup moved the 82xx/PQ2 options over into arch/powerpc/platforms/82xx/Kconfig where they belong. It also killed GEN550 which doesn't exist in arch/powerpc.

2007-02-07[POWERPC] Fix kernel build errors for mpc8272ads and mpc8560adsVitaly Bordug3-4/+5
Recent update of asm-powerpc/io.h caused cpm-related stuff to break in the current kernel. Current patch fixes it, as well as other inconsistencies expressed, that do not permit targets from working properly: - Updated dts with a chosen node with interrupt controller, - fixed messed device IDs among CPM2 SoC devices, - corrected odd header name and fixed type in defines, - Added 82xx subdir to the powerpc/platforms Makefile, missed during initial commit, - new solely-powerpc header file for 8260 family (was using one from arch/ppc, this one cleaned up from the extra stuff), in fact for now a placeholder to get the board-specific includes for stuff not yet capable to live with devicetree peeks only - Fixed couple of misprints in reference mpc8272 dts.

2006-12-04[POWERPC] Make pci_read_irq_line the defaultBenjamin Herrenschmidt1-13/+0
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.

2006-10-03POWERPC: mpc82xx merge: board-specific/platform stuff(resend)Vitaly Bordug6-0/+884
This intruduces 82xx family in arch/powerpc/platforms, and has all the board-specific code to represent regression-less transaction from ppc. The functionality is apparently the same, including PCI controller. Signed-off-by: Vitaly Bordug <vbordug@ru.mvista.com>
