48723535b4 Merge booke and aim interrupt.c files.
Summary:
Both booke and AIM interrupt.c files contain nearly identical code.  This merges
the two files, to reduce duplication.

42a03d267c Add a PCI bridge for the Freescale PCIe Root Complex
Summary:
The Freescale PCIe Root Complex shows up as a Processor class device, PowerPC
subclass, so the generic PCI code ignores it for a bridge.  This adds support
for it.

As part of this, update the Freescale PCI hostbridge driver, to allow probing
beyond the root complex, instead of only allowing "proper" PCI-PCI bridges.

eacabb45b2 Implement a driver for the PowerPC-base RouterBoard (RB333/600/800/1100)
Summary:
This has been tested on the RB800, but should work on the RB333, RB600, and
RB1100 as well.

It's currently missing ECC support, but read and write are complete.

e2e2bd33d3 Make simplebus a base class of ofwbus. This allows the elimination of
duplicated code in the two classes, and also allows devices in FDT-based
systems to declare simplebus as their parent and still work correctly
when the FDT data describes the device at the root of the tree rather
than as a child of a simplebus (which is common for interrupt, clock,
and power controllers).

49dd1c9d72 Remove FreeBSD/wii.
This port failed to gain traction and probably only a couple Wii consoles
ran FreeBSD all the way to single user mode with an md(4). IPC
support was never implemented, so it was impossible to use any peripheral

Any further development, if any, will happen at https://github.com/rpaulo/wii.

For compatibility, 'device windtunnel' is still supported, but one should use
'device adm1030' instead, and this has been updated in GENERIC and NOTES.

991a1f338d Merge all MD sf_buf allocators into one MI, residing in kern/subr_sfbuf.c
The MD allocators were very common, however there were some minor
differencies. These differencies were all consolidated in the MI allocator,
under ifdefs. The defines from machine/vmparam.h turn on features required
for a particular machine. For details look in the comment in sys/sf_buf.h.

As result no MD code left in sys/*/*/vm_machdep.c. Some arches still have
machine/sf_buf.h, which is usually quite small.

GENERIC64 for PowerPC to use vt with it.

Much to my chagrin, PS3 support seems to have bitrotted somewhat since the
last time I tried it. ehci panics on attach and interrupt handling seems
to be faulty. This should be fixed soon...

The PowerPC 970 processors have two different types of events: direct events
and indirect events.  Thus far only direct events are supported.  I included

506e4ba257 Split the function of the PCB_FPU flags into two: PCB_FPU now indicates that
the actual FPU is enabled, while PCB_FPREGS indicates that the FPU state
structure in the PCB is valid. This separation reflects the situation on
FPU-less systems in which the FP state is used by the emulator but we don't
actually want to try to turn on the non-existant FPU.

Use this flag to save and restore FP regs properly on both AIM and Book-E.
As a side effect, this sets up hard-FP and Altivec on Book-E CPUs with such
abilities except for a trap handler to call enable_fpu()/enable_altivec().

f5869d9275 Following the approach with ACPI DMAR on x86, split IOMMU handling into
a variant PCI bus instead of trying to shoehorn it into the PCI host bridge
adapter. Besides matching better the architecture on other platforms, this
also allows systems with multiple partitionable endpoints per PCI host
bridge to work correctly.

a1b4155638 Follow up r223485, which made AIM use the ABI thread pointer instead of
PCPU fields for curthread, by doing the same to Book-E. This closes
some potential races switching between CPUs. As a side effect, it turns out
the AIM and Book-E swtch.S implementations were the same to within a few
registers, so move that to powerpc/powerpc.

1c2bed6f18 Rename the "bare" platform "mpc85xx", which is what it actually is, and
add actual platform probing based on PVR. Still needs a little more work:
in particular, the CCRS setup should move here.

Also turn "bare" into a truly bare platform that doesn't pretend to know how
to do anything except get the memory map. This should also be enhanced to
process the FDT reserved memory list, but that is for another day.

22459a6d41 Make tsec work with the device tree present on the RB800. The previous code
assumed that the MDIO bus was a direct child of the Ethernet interface. It
may not be and indeed on many device trees is not. While here, add proper
locking for MII transactions, which may be on a bus shared by several MACs.

- Unify the identical macio/fdt/mambo OpenPIC drivers into one
- Be more forgiving (following ePAPR) about what we need from the device
  tree to identify an OpenPIC
- Correctly map all IRQs into an interrupt domain
- Set IRQ_*_CONFORM for interrupts on an unknown PIC type instead of
  failing attachment for that device.

9d999e98ee Merge in support for PAPR-compliant (Power Architecture Platform
Requirements) systems from the projects/pseries branch. This in principle
includes all IBM POWER hardware released in the last 15 years with the
exception of POWER3-based systems when run in 64-bit mode. The main
development target, however, has been the PAPR logical partition support
that is the default target in KVM on POWER and QEMU -- mileage may vary
on actual hardware at present. Much of the heavy lifting here was done
by Andreas Tobler.
