xlate_iomm_address() really wants the ds_addr to pass to the HV, so store
that value (instead of the BAR number) when we allocate the device bars.
This is not a fast path, so we can look up the device_node property
there instead of using the bussubno field of the pci_dn.

The other user of iseries_ds_addr() was already scanning the device tree,
so looking up a property will not slow it down any more.

Similar to of_find_compatible_node(), of_find_matching_node() and
for_each_matching_node() allow you to iterate over the device tree
looking for specific nodes, except that they take of_device_id
tables instead of strings.

This also moves of_match_node() from driver/of/device.c to
driver/of/base.c to colocate it with the of_find_matching_node which
depends on it.

The logic that checks to see if a machine check is caused by an NMI will
always match when NMI hasn't been initialized, since the mpic routine

By default the OpenPIC on PWRficient will bias to one core (since that
will improve changes of the other core being able to stay idle/powered
down). However, this conflicts with most irq load balancing schemes,
since setting an interrupt to be delivered to either core doesn't really
result in the load being shared. It also doesn't work well with the
soft irq disable feature of PPC, since EE will stay on until the first
interrupt is taken while soft disabled.

Set the gconf0 config bit that enables even distribution of interrupts
among the two cores.

Some PWRficient-based boards have a NMI button that's wired up to a GPIO
as interrupt source. By configuring the openpic accordingly, these get
delivered as a machine check with high priority, instead of as an external
interrupt.

The device tree contains a property "nmi-source" in the openpic node
for these systems, and it's the (hwirq) source for the input.

Also, for these interrupts, the IACK is read from another register than
the regular (MCACK instead), but they are EOI'd as usual. So implement
said function for the mpic driver.

Finally, move a couple of external function defines to include/ instead
of local under sysdev. Being able to mask/unmask and eoi directly saves
us from setting up a dummy irq handler that will never be called.

This makes 4xx embedded platforms re-assign all PCI resources as we
pretty much never care about what the various firmwares have done on
these, it's generally not compatible with the way the kernel will map
the bridges.

We still need to also enable bus renumbering on some of them, but I
will do that from a separate patch after I've fixed 4xx PCIe to handle
all bus numbers.

Brings EP405 support to arch/powerpc. The IRQ routing for the CPLD
comes from a device-tree property, PCI is working to the point where
I can see the video card, USB device, and south bridge.

This should work with both EP405 and EP405PC.

I've not totally figured out how IRQs are wired on this hardware
though, thus at this stage, expect only USB interrupts working,
pretty much the same as what arch/ppc did.

Also, the flash, nvram, rtc and temp control still have to be wired.

This adds a cputable function pointer for the CPU-side machine
check handling. The semantic is still the same as the old one,
the one in ppc_md. overrides the one in cputable, though
ultimately we'll want to change that so the CPU gets first.

This removes CONFIG_440A which was a problem for multiplatform
kernels and instead fixes up the IVOR at runtime from a setup_cpu
function. The "A" version of the machine check also tweaks the
regs->trap value to differenciate the 2 versions at the C level.
