- Bonito64 north bridge converted to 3-phase reset API
- PCI refactors around PIIX devices
- Support for nanoMIPS in bootloader generator API
- New YAMON Malta Avocado test
- Removal of 'trap and emulate' KVM support
- System-specific QMP commands restricted to system emulation

hw/intc: Extract the IRQ counting functions into a separate file

These IRQ counting functions will soon be required in binaries that
do not include the APIC code, too, so let's extract them into a
separate file that can be linked independently of the APIC code.

While we're at it, change the apic_* prefix into kvm_* since the
functions are used from the i8259 PIC (i.e. not the APIC), too.

hw/intc/arm_gicv3_cpuif: Support vLPIs

The CPU interface changes to support vLPIs are fairly minor:
in the parts of the code that currently look at the list registers
to determine the highest priority pending virtual interrupt, we
must also look at the highest priority pending vLPI. To do this
we change hppvi_index() to check the vLPI and return a special-case
value if that is the right virtual interrupt to take. The callsites
(which handle HPPIR and IAR registers and the "raise vIRQ and vFIQ
lines" code) then have to handle this special-case value.

This commit includes two interfaces with the as-yet-unwritten
redistributor code:
* the new GICv3CPUState::hppvlpi will be set by the redistributor
(in the same way as the existing hpplpi does for physical LPIs)
* when the CPU interface acknowledges a vLPI it needs to set it
to non-pending; the new gicv3_redist_vlpi_pending() function
(which matches the existing gicv3_redist_lpi_pending() used
for physical LPIs) is a stub that will be filled in later

hw/intc/arm_gicv3_cpuif: Split "update vIRQ/vFIQ" from gicv3_cpuif_virt_update()

The function gicv3_cpuif_virt_update() currently sets all of vIRQ,
vFIQ and the maintenance interrupt. This implies that it has to be
used quite carefully -- as the comment notes, setting the maintenance
interrupt will typically cause the GIC code to be re-entered
recursively. For handling vLPIs, we need the redistributor to be
able to tell the cpuif to update the vIRQ and vFIQ lines when the
highest priority pending vLPI changes. Since that change can't cause
the maintenance interrupt state to change, we can pull the "update
vIRQ/vFIQ" parts of gicv3_cpuif_virt_update() out into a separate
function, which the redistributor can then call without having to
worry about the reentrancy issue.

results to a function in the redistributor which will do the
actual operation. As with the "make a VLPI pending" change,
for the moment we leave that redistributor function as a stub,
to be implemented in a later commit.

hw/intc/arm_gicv3_its: Implement INV command properly

We were previously implementing INV (like INVALL) to just blow away
cached highest-priority-pending-LPI information on all connected
redistributors. For GICv4.0, this isn't going to be sufficient,
because the LPI we are invalidating cached information for might be
either physical or virtual, and the required action is different for
those two cases. So we need to do the full process of looking up the
ITE from the devid and eventid. This also means we can do the error
checks that the spec lists for this command.

Split out INV handling into a process_inv() function like our other
command-processing functions. For the moment, stick to handling only
physical LPIs; we will add the vLPI parts later.

The VSYNC command forces the ITS to synchronize all outstanding ITS
operations for the specified vPEID, so that subsequent writes to
GITS_TRANSLATER honour them. The QEMU implementation is always in
sync, so for us this is a nop, like the existing SYNC command.

hw/intc/arm_gicv3_its: Implement VMOVP

Implement the GICv4 VMOVP command, which updates an entry in the vPE
table to change its rdbase field. This command is unique in the ITS
command set because its effects must be propagated to all the other
ITSes connected to the same GIC as the ITS which executes the VMOVP
command.

The GICv4 spec allows two implementation choices for handling the
propagation to other ITSes:
* If GITS_TYPER.VMOVP is 1, the guest only needs to issue the command
on one ITS, and the implementation handles the propagation to
all ITSes
* If GITS_TYPER.VMOVP is 0, the guest must issue the command on
every ITS, and arrange for the ITSes to synchronize the updates
with each other by setting ITSList and Sequence Number fields
in the command packets

We choose the GITS_TYPER.VMOVP = 1 approach, and synchronously
execute the update on every ITS.

For GICv4.1 this command has extra fields in the command packet and
additional behaviour. We define the 4.1-only fields with the FIELD
macro, but only implement the GICv4.0 version of the command.

Note that we don't update the reported GITS_TYPER value here;
we'll do that later in a commit which updates all the reported
feature bit and ID register values for GICv4.

hw/intc/arm_gicv3_its: Handle virtual interrupts in process_its_cmd()

For GICv4, interrupt table entries read by process_its_cmd() may
indicate virtual LPIs which are to be directly injected into a VM.
Implement the ITS side of the code for handling this. This is
similar to the existing handling of physical LPIs, but instead of
looking up a collection ID in a collection table, we look up a vPEID
in a vPE table. As with the physical LPIs, we leave the rest of the
work to code in the redistributor device.

The redistributor half will be implemented in a later commit;
for now we just provide a stub function which does nothing.

and VMAPTI is that VMAPI assumes vINTID == EventID rather than
both being specified in the command packet.

(This code won't be reachable until we allow the GIC version to be
set to 4. Support for reading this new virtual-interrupt DTE and
handling it correctly will be implemented in a later commit.)
