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

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.

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.

This supports e500v1, e500v2, and e500mc. Tested only on e500v2, but the
performance counters are identical across all, with e500mc having some
additional events.

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).

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.
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.

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...

fixes FDT on x86 and will make coexistence with ACPI on ARM systems easier.

This also fixes asserts on removal of the module for the mpc74xx.
The PowerPC 970 processors have two different types of events: direct events
and indirect events. Thus far only direct events are supported. I included
some documentation in the driver on how indirect events work, but support is
for the future.

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().

adapter. Besides matching better the architecture on other platforms, this
also allows systems with multiple partitionable endpoints per PCI host
bridge to work correctly.
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

registers, so move that to powerpc/powerpc.

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.
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.

- Use bus reference phandles in place of FDT offsets as IRQ domain keys
- 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.

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.
