This option allows the VIA configuration to be controlled between 3
different possible setups: cuda, pmu-adb and pmu with USB rather than ADB
keyboard/mouse.
For the moment we don't do anything with the configuration except to pass
it to the macio device (the via-cuda parent) and also to the firmware via
the fw_cfg interface so that it can present the correct device tree.
The default is cuda which is the current default and so will have no

Add support for multiple IOMMU indexes to the IOMMU notifier APIs.
When initializing a notifier with iommu_notifier_init(), the caller
must pass the IOMMU index that it is interested in. When a change
happens, the IOMMU implementation must pass
memory_region_notify_iommu() the IOMMU index that has changed and
that notifiers must be called for.
IOMMUs which support only a single index don't need to change.
Callers which only really support working with IOMMUs with a single
index can use the result of passing MEMTXATTRS_UNSPECIFIED to
memory_region_iommu_attrs_to_index().

The ASPEED SoCs contain a single register that returns random data when
read. This models that register so that guests can use it.
The random number data register has a corresponding control register,
however it returns data regardless of the state of the enabled bit, so
the model follows this behaviour.
When the qcrypto call fails we exit as the guest uses the random number
device to feed it's entropy pool, which is used for cryptographic
purposes.

For the IoTKit MPC support, we need to wire together the
interrupt outputs of 17 MPCs; this exceeds the current
value of MAX_OR_LINES. Increase MAX_OR_LINES to 32 (which
should be enough for anyone).
The tricky part is retaining the migration compatibility for
existing OR gates; we add a subsection which is only used
for larger OR gates, and define it such that we can freely
increase MAX_OR_LINES in future (or even move to a dynamically
allocated levels[] array without an upper size limit) without

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.

Remove the now-unused armv7m_init() function. This was a legacy from
before we properly QOMified ARMv7M, and it has some flaws:
* it combines work that needs to be done by an SoC object (creating
and initializing the TYPE_ARMV7M object) with work that needs to
be done by the board model (setting the system up to load the ELF
file specified with -kernel)
* TYPE_ARMV7M creation failure is fatal, but an SoC object wants to
arrange to propagate the failure outward
* it uses allocate-and-create via qdev_create() whereas the current
preferred style for SoC objects is to do creation in-place
Board and SoC models can instead do the two jobs this function
was doing themselves, in the right places and with whatever their
preferred style/error handling is.

add_link() doesn't add a reference to the target object, while

Furthemore, OBJ_PROP_LINK_UNREF_ON_RELEASE flags, set during add_link,
says whether a reference must be released when the property is destroyed.

By default, the IOMMU model built into the spapr virtual PCI host bridge
supports 4kiB and 64kiB IOMMU page sizes. However this can be overridden
which may be desirable to allow larger IOMMU page sizes when running a
guest with hugepage backing and passthrough devices. For that reason a
warning was printed when the device wasn't configured to allow the pagesize
with which guest RAM is backed.
Experience has proven, however, that this message is more confusing than
useful. Worse it sometimes makes little sense when the host-available page
sizes don't match those available on the guest, which can happen with
a POWER8 guest running on a POWER9 KVM host.
Long term we do want better handling to allow large IOMMU page sizes to be
used, but for now this parameter and warning don't really accomplish it.
So, remove the message, pending a better solution.

Factor out memory unplug into separate function from spapr_lmb_release().
Then use generic hotplug_handler_unplug() to trigger memory unplug,
which will call spapr_machine_device_unplug() -> spapr_memory_unplug()
in the end.
This way unplug operation is not buried in lmb internals and located in
the same place like in other targets, following similar logic/call chain
across targets.

We'll be handling unplug of e.g. CPUs and PCDIMMs via the general
hotplug handler soon, so let's add that handler function.

Let's finish cleaning up the hotplug handler. This check can be
performed in the pre_plug code as the very first thing.

Let's clean the hotplug handler up by moving lookup of the node into

Make it more readable by converting register indexes to decimal
(avoids lot of superfluous 0x0) and distinguish errors caused by
accessing non-existent vs. unimplemented registers.
No functional change.

The timers are configured in the mos6522 init function and therefore will
always exist, so the function can never return false.
Peter also pointed out that this is the only remaining user of
VMSTATE_TIMER_PTR_TEST in the codebase, so we might as well just convert it
over to VMSTATE_TIMER_PTR and remove mos6522_timer_exist() as it is no
longer required.

The 6522 VIA timer frequency cannot be set by altering registers within the
device itself and hence it is a fixed property of the machine.
Move the initialisation of the timer frequency to the mos6522 reset function
and ensure that any subclasses always call the parent reset function so that
it isn't required to store the timer frequency within vmstate_mos6522_timer
itself.
By moving the frequency initialisation to the device reset function then we
find that the realize function for both mos6522 and mos6522_cuda becomes
obsolete and can simply be removed.

Examining the migration stream it can be seen that the mos6522 device state is
being stored separately rather than as part of the CUDA device which is
incorrect (and likely to cause issues if another mos6522 device is added to
the machine).
Resolve this by embedding the mos6522_cuda device directly within the CUDA
device rather than using a QOM object link to reference the device separately.
Note that we also bump the version in vmstate_cuda to reflect this change: this
isn't particularly important for the moment as the Mac machine migration isn't
100% reliable due to issues migrating the timebase under TCG.

This was accidentally introduced when extracting the 6522 VIA functionality
from the CUDA device, and prevents loadvm from completing successfully.
