3c5ede8cc6 [POWERPC] Revert "[POWERPC] Add 'mdio' to bus scan id list for platforms with QE UEC"
This reverts commit 3baee95595.

That commit was a mistake from the start; I added mdio type to the
bus scan list early on in my ucc_geth migrate to phylib development,
which is just pure wrong (the ucc_geth_mii driver creates the mii
bus and the PHY layer handles PHY enumeration without translation).

This follows on from commit 77926826f3:

 Revert "[POWERPC] Don't complain if size-cells == 0 in prom_parse()"

which was basically trying to hide a symptom of the original mistake
this revert fixes.

2e56ff206b [POWERPC] Make endianess of cfg_addr for indirect pci ops runtime
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.

0a3786c5f7 [POWERPC] Removed remnants of bus_offset
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.

7d52c7b0cd [POWERPC] Pass the pci_controller into pci_exclude_device
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

5ab9c4524d [POWERPC] Remove set_cfg_type for PCI indirect users that don't need it
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.

When CONFIG_PCI is disabled, the definitions for isa_io_base,

can result in link failure because they are defined in multiple

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

Choosing between the embedded platforms and the multiplatform code is
now done in the platform menu, but functionally everything stays the

c75f902b93 [POWERPC] 83xx: Don't call ioremap in the reset function
It's possibly that we get an reset requestion when interrupts are disabled.
(For example an oops in an interrupt handler).  Therefor, we can't call
ioremap in the reset function.  Moving the ioremap of the registers we
need access to an arch_initcall helps the problem.

However we still have a window between boot and the arch_initcall in
which the register pointer will not be setup and thus we spin if the reset
function is called.  If one needs to ensure even this case is covered, look
at use of the watchdog provided on 83xx to reset the processor.

69108cf006 [POWERPC] Remove ppc_md.pci_map_irq & ppc_swizzle for ARCH=powerpc
These were inherited from ARCH=ppc, but are not needed since parsing of interrupts
should be done via the of_* functions (who can do swizzling). If we ever need to
do non-standard swizzling on bridges without a device-node, then we might add
back a slightly different version of ppc_md.pci_swizzle but for now, that is not
the case.

I removed the couple of calls for these in 83xx. If that breaks something, then
there is a problem with the device-tree on these.

f90bb153b1 [POWERPC] Make pci_read_irq_line the default
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.
