As we make upper bits in IO and prefetcheable memory
registers writeable, we should declare support
for 64 bit prefetcheable memory and 32 bit io
in the bridge.

This changes the default for apb, dec, but I'm guessing
they got the defaults wrong by accident.
Alternatively, we could let bridges declare lack of
64 bit support and make the upper bits read-only zero.

This adds support for a standard pci to pci bridge,
enabling support for more than 32 PCI devices in the system.
Device hotplug is supported by means of SHPC controller.
For guests with an SHPC driver, this allows robust hotplug
and even hotplug of nested bridges, up to 31 devices
per bridge.

This capability makes it possible for the guest to
report a unique chassis identifier to the user.

The spec also recommends making chassis indentifier
persist in eeprom.
This isn't implemented.

This adds support for SHPC interface, as defined by PCI Standard
Hot-Plug Controller and Subsystem Specification, Rev 1.0
http://www.pcisig.com/specifications/conventional/pci_hot_plug/SHPC_10

Only SHPC intergrated with a PCI-to-PCI bridge is supported,
SHPC integrated with a host bridge would need more work.

All main SHPC features are supported:
- MRL sensor
- Attention button
- Attention indicator
- Power indicator

Wake on hotplug and serr generation are stubbed out but unused
as we don't have interfaces to generate these events ATM.

One issue that isn't completely resolved is that qemu currently
expects an "eject" interface, which SHPC does not provide: it merely
removes the power to device and it's up to the user to remove the device
from slot. This patch works around that by ejecting the device
when power is removed and power LED goes off.

For a pci bridge device, if we don't override
the name with custom code, the bus will be addressed as
<id>.0, where id is the id specified by the user.

Since PCI Bridge devices have a single bus each, we don't need
the index: address the bus using the parent device name.
This is better since this way users don't care about
our internal bus/device distinctions.

As far as I could see, we only have built-in
bridges at this point which always override the
name. So this change will only affect ioh3420.c.

Actually, pci_parse_devaddr checks if the dom/bus of the PCI address exist. But
this should be the jobs of a caller. In fact, the two callers of this function
will try to retrieve the PCIBus related to the devaddr and return an error if
they cannot.

Commit 9b9a970a
(target-lm32/microblaze: Typedef struct CPU{MB,LM32}State)
introduced necessary typedefs for cpu_mmu_index() and mmu.h
respectively.

On some GCC versions this leads to "error: redefinition of typedef".

Drop the original typedef to hopefully fix the build.

The threaded VNC servers messed up with QEMU fd handlers without
any kind of locking, and that can cause some nasty race conditions.

Using qemu_mutex_lock_iothread() won't work because vnc_dpy_cpy(),
which will wait for the current job queue to finish, can be called with
the iothread lock held.

Instead, we now store the data in a temporary buffer, and use a bottom
half to notify the main thread that new data is available.

vnc_[un]lock_ouput() is still needed to access VncState members like
abort, csock or jobs_buffer.

Reintroduce CPUState as QOM object: It's abstract and derived directly
from TYPE_OBJECT for compatibility with the user emulators.
The identifier CPUState avoids conflicts between CPU() and the struct.

Introduce $(qom-twice-y) to build it separately for system and for user
emulators.

Prepare a virtual reset method, (re)introduce cpu_reset() as wrapper.
