* [POWERPC] Use ppc64 style list management for pci_controller on ppc32Kumar Gala2007-06-294-122/+94
| | | | | | | | Use the ppc64 style list management and allocation functions for pci_controllers. This makes the pci_controller structs just a bit more common between ppc32 & ppc64. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | 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>
* [POWERPC] Use global_number in ppc32 pci_controllerKumar Gala2007-06-298-30/+64
| | | | | | | | | Make the pci_controller struct use global_number for the PHB domain number instead of index to match what ppc64 does and reuse its pci_domain_nr code. Introduced a pci-common.c to handle shared code between ppc32 & ppc64. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | Moved bits need for ppc32 from asm-ppc/pci-bridge.h into asm-powerpc/pci-bridge.h. Removed ARCH=powerpc specific bits (and comments related to ARCH=ppc) from asm-ppc/pci-bridge.h as its only used on ARCH=ppc. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* [POWERPC] 86xx: Created quirk_fsl_pcie_transparent() to initialize bridge ↵Zhang Wei2007-06-291-0/+37
| | | | | | | | | | | | | | | | | | | resources. The Freescale PCI-e RC poses as a transparent bridge, but does not implement the IO_BASE or IO_LIMIT registers in the config space. This means that the code which initializes the bridge resources ends up setting the IO resources erroneously. Add quick_fsl_pcie_transparent() to handle this. This change sets RC of mpc8641 to be a transparent bridge for legacy I/O access and initializes the RC bridge resources from the device tree.

* [POWERPC] Let subordinate transparent bridges be transparent.York Sun2007-06-291-1/+1
| | | | | | | | | | | | | | | In pcibios_fixup_bus(), bridges that are subordinate to transparent bridges were still relocating their IORESOURCE_IO and IO_RESOURCE_MEM start and end values. Fix this by preventing the transparent bridge from relocating the start and end values, thus allowing the subordinate non-transparent bridge full molestation rights.

| | | | | | | | Set IDE in ULI1575 to not 100% native mode, which forces the IDE driver to probe the irq itself. Signed-off-by: Zhang Wei <wei.zhang@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* [POWERPC] 86xx: Workaround PCI_PRIMARY_BUS usageKumar Gala2007-06-293-1/+14
| | | | | | | | | | | | | | | The Freescale PCI-e controllers have an issue in that they use the PCI_PRIMARY_BUS register in the virtual P2P bridge to determine which bus number to match on when generating a type 0 config cycle. The issue is if we are renumbering bus numbers to match Linux we will try setting the PCI_PRIMARY_BUS and will not know which bus number to use for generating type 0 config cycles. We surpress writing the register in the P2P bridge and always keep it at zero. In the future when proper PCI domain support is working we should be able to remove this.

* [POWERPC] 86xx: Avoid system halt if link training isn't at least L0.Zhang Wei2007-06-291-1/+10

* [POWERPC] Added indirect_type to handle variants of PCI opsKumar Gala2007-06-292-6/+26
| | | | | | | | | | | | The generic PCI config ops indirect support for ppc32 covers only two cases (implicit vs explicit) type 0/1 config cycles via set_cfg_type. Added a indirect_type bit mask to handle other variants. Added support for PCI-e extended registers and moved the cfg_type handling into the bit mask for ARCH=powerpc. We can also use this to handle indirect quirks. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* [POWERPC] Removed remnants of bus_offsetKumar Gala2007-06-295-5/+6
| | | | | | | | | | | Removed the remants of bus_offset and use self_busno in the mv64x60 case and use pci_assign_all_buses on 83xx/85xx. 83xx/85xx have multiple PHBs and the firmwares on these devices tend not to handle topologies with P2P bridges well so we let Linux just reassign the bus numbers to match. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* [POWERPC] Added self_busno to indicate which bus number the PHB isKumar Gala2007-06-292-2/+11
| | | | | | | | | Added self_busno to pci_controller and indirect PCI ops to be set by board code to indicate which bus number to use when talking to the PHB. By default we use zero since the majority of controllers that have implicit mechanisms to talk to the PHBs use a bus number of zero. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* [POWERPC] Remove bus_offset in places its not really usedKumar Gala2007-06-292-5/+4
| | | | | | | | 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>
* [POWERPC] Remove hack to determine the 2nd PHBs bus numberKumar Gala2007-06-293-16/+2
| | | | | | | | | 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>
* [POWERPC] Pass the pci_controller into pci_exclude_deviceKumar Gala2007-06-2917-21/+165
| | | | | | | | | | 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.

* [POWERPC] 52xx: Remove support for PCI bus_offsetKumar Gala2007-06-291-5/+4
| | | | | | | The hose->bus_offset is only used for PCI config cycles and the 52xx PCI config code doesn't actually ever set bus_offset to a non-zero value. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* [POWERPC] Remove set_cfg_type for PCI indirect users that don't need itKumar Gala2007-06-297-9/+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>

| | | | | | | | | | | The TSI108 code and the 32 bit powermac and chrp platforms have dependency on PCI that is not easy or desirable to get rid of. The easiest fix is to always select CONFIG_PCI if one of those platforms is enabled. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

| | | | | | | | | | | 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>

* [POWERPC] rename add_bridge to avoid namespace clashesArnd Bergmann2007-06-2921-30/+28
| | | | | | | | | 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>

| | | | | | | | | | | | 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>
* [POWERPC] In booting-without-of.txt, clarify that properties must precede ↵David Gibson2007-06-281-0/+8
| | | | | | | | | | | | | | | | | | | subnodes A strict reading of the flattened device tree format defined in booting-without-of.txt does in fact require that all the tags defining properties for a node go before any definitions of subnodes, however it's not particularly emphasised. Although allowing intermingled properties and subnodes would not be ambiguous in meaning, the kernel parser does currently require that properties precede subnodes. Furthermore, keeping this constraint makes life easier for various device tree scanning tools. Therefore, re-emphasise in booting-without-of.txt that this is a strict requirement of the flattened device tree format.

* [POWERPC] Make more OF-related bootwrapper functions available to non-OF ↵David Gibson2007-06-284-39/+45
| | | | | | | | | | | | | | | | | | | | platforms Commit 2e6016133755eb3cc44e8efab92573d23ed75888 split up arch/powerpc/boot/of.c so that some OF functions can be used on platforms that don't want to use the overall OF platform boot code. This is useful on things like PReP which can have an OF implementation which is useful for debugging output, but inadequate for booting. However, that commit didn't export quite enough things to make a usable OF console on a non-OF system. In particular, the device tree manipulation performed to initialize the OF console code must explicitly use the OF device tree, rather than the flattened device tree, even if the system is otherwise booting using a flattened device tree. This makes it so. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>

* [POWERPC] Move iSeries_tb_recal into its own late_initcall.Tony Breeds2007-06-283-15/+23
| | | | | | | | | | | | | | | Currently iSeries will recalibrate the cputime_factors in the first settimeofday() call. It seems the reason for doing this is to ensure a resaonable time delta after time_init(). On current kernels (with udev), this call is made 40-60 seconds into the boot process, by moving it to a late initcall it is called approximately 5 seconds after time_init() is called. This is sufficient to recalibrate the timebase. Signed-off-by: Tony Breeds <tony@bakeyournoodle.com> CC: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
