hw/display: add ramfb, a simple boot framebuffer living in guest ram
The boot framebuffer is expected to be configured by the firmware, so it
uses fw_cfg as interface. Initialization goes as follows:
(1) Check whenever etc/ramfb is present.
(2) Allocate framebuffer from RAM.
(3) Fill struct RAMFBCfg, write it to etc/ramfb.
Done. You can write stuff to the framebuffer now, and it should appear
automagically on the screen.
Note that this isn't very efficient because it does a full display
update on each refresh. No dirty tracking. Dirty tracking would have
to be active for the whole ram slot, so that wouldn't be very efficient
either. For a boot display which is active for a short time only this
isn't a big deal. As permanent guest display something better should be
used (if possible).
This is the ramfb core code. Some windup is needed for display devices
which want have a ramfb boot display.

spapr: fix xics_system_init() error path
Commit
3d85885a1b1f3 tried to fix error handling, but it actually
went into the wrong direction by dropping the local Error *.
In the default KVM case, the rationale is to try the in-kernel XICS first,
and if not possible, to fallback to userland XICS. Passing errp everywhere
makes this fallback impossible if errp is &error_fatal (which happens to
be the case). And anyway, if the caller would pass a regular &local_err,
things would be worse: we could possibly pass an already set *errp to
error_setg() and crash, or return an error even in case of success.
So we definitely need a local Error * and only propagate it when we're
done with the fallback logic. This is what this patch does.

target/ppc, spapr: Move VPA information to machine_data
CPUPPCState currently contains a number of fields containing the state of
the VPA. The VPA is a PAPR specific concept covering several guest/host
shared memory areas used to communicate some information with the
hypervisor.
As a PAPR concept this is really machine specific information, although it
is per-cpu, so it doesn't really belong in the core CPU state structure.
There's also other information that's per-cpu, but platform/machine
specific. So create a (void *)machine_data in PowerPCCPU which can be
used by the machine to locate per-cpu data. Intialization, lifetime and
cleanup of machine_data is entirely up to the machine type.

spapr_cpu_core: add missing rollback on realization path
The spapr_realize_vcpu() function doesn't rollback in case of error.
This isn't a problem with coldplugged CPUs because the machine won't
start and QEMU will exit. Hotplug is a different story though: the
CPU thread is started under object_property_set_bool() and it assumes
it can access the CPU object.
If icp_create() fails, we return an error without unregistering the
reset handler for this CPU, and we let the underlying QEMU thread for
this CPU alive. Since spapr_cpu_core_realize() doesn't care to unrealize
already realized CPUs either, but happily frees all of them anyway, the
CPU thread crashes instantly:

spapr_cpu_core: fix potential leak in spapr_cpu_core_realize()
Commit
94ad93bd97684 (QEMU 2.12) switched to instantiate CPUs separately
but it missed to adapt the error path accordingly. If something fails in
the CPU creation loop, then the CPU object that was just created is leaked.
The error paths in this function are a bit obfuscated, and adding
yet another label to free this CPU object makes it worse. We should
move the block of the loop to a separate function, with a proper
rollback path, but this is a bigger cleanup.
For now, let's just fix the bug by adding the missing calls to
object_unref(). This will allow easier backport to older QEMU

* It makes the kernel use the set "console device" as a console

Given that way too many error conditions may occur, and detecting the

Because of the console device type selection criteria (by machine

arm: Don't crash if user tries to use a Cortex-M CPU without an NVIC
The Cortex-M CPU and its NVIC are two intimately intertwined parts of
the same hardware; it is not possible to use one without the other.
Unfortunately a lot of our board models don't do any sanity checking
on the CPU type the user asks for, so a command line like
qemu-system-arm -M versatilepb -cpu cortex-m3
will create an M3 without an NVIC, and coredump immediately.
In the other direction, trying a non-M-profile CPU in an M-profile
board won't blow up, but doesn't do anything useful either:
qemu-system-arm -M lm3s6965evb -cpu arm926
Add some checking in the NVIC and CPU realize functions that the
user isn't trying to use an NVIC without an M-profile CPU or
an M-profile CPU without an NVIC, so we can produce a helpful
error message rather than a core dump.

* TYPE_ARMV7M creation failure is fatal, but an SoC object wants to
