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.

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.

This adds device nodes for the PCI bridges as well as the ISA devices on the newer revision MPC8641HPCN. It also adds the PCI ranges to the soc node so that address translation for the ISA devices works properly.

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.

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>

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>

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>

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.

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>

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>

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>

Arnd Bergmann authored
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>

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.

asm-powerpc/processor.h declares, and arch/ppc/platforms/prep_setup.c defines variables ucBoardRev, ucBoardRevMaj and ucBoardRevMin which are used nowhere in the current kernel (neither in arch/ppc nor arch/powerpc).

Commit 2e601613 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>

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>
