Adds support for suspend/resume for VIO devices. This is needed for
support for HMC initiated hibernation.

Enables support for HMC initiated partition hibernation. This is
a firmware assisted hibernation, since the firmware handles writing
the memory out to disk, along with other partition information,
so we just mimic suspend to ram.

The main benefit of using ACPI host bridge window information is that
we can do better resource allocation in systems with multiple host bridges,
e.g., http://bugzilla.kernel.org/show_bug.cgi?id=14183
Sometimes we need _CRS information even if we only have one host bridge,
e.g., https://bugs.laun
Previously we used a table of size PCI_BUS_NUM_RESOURCES (16) for resources
forwarded to a bus by its upstream bridge. We've increased this size
several times when the table overflowed.
But there's no good limit on the number of resources because host bridges
and subtractive decode bridges can f
No functional change; this converts loops that iterate from 0 to
PCI_BUS_NUM_RESOURCES through pci_bus resource[] table to use the
pci_bus_for_each_resource() iterator instead.
This doesn't change the way resources are stored; it merely removes
dependencies on the fact that they're in a table.

No functional change; this fills in the bus subtractive decode resources
after reading the bridge window information rather than before. Also,
print out the subtractive decode resources as we already do for the
positive decode windows.

No functional change; this breaks up pci_read_bridge_bases() into separate
pieces for the I/O, memory, and prefetchable memory windows, similar to how
Yinghai recently split up pci_setup_bridge() in 68e84ff3bdc.

Historically, Linux has assumed a single PCI host bridge, with that bridge
claiming all the address space left after RAM and legacy devices are taken out.
If the system contains multiple host bridges, we can no longer operate under
that assumption. We have to know what parts of the address space

Here's the update (only added EXPORT_SYMBOL_GPL for pci_resource_n).
I'll repost the whole series if that's easier for you.

PCI: augment bus resource table with a list
Any special reason this in MPC5121 Revision 2 only?
I did not see anything that contradicted the rev 3 manual in the code.
But there is one harmless bug (since the NFC_CMD_FAIL symbol is never used),
i.e.
