QEMU model of the GPIO device on the SiFive E300 series SOCs.
The pins are not used by a board definition yet, however this
implementation can already be used to trigger GPIO interrupts from the
software by configuring a pin as both output and input.

The ICC_CTLR_EL3 register includes some bits which are aliases
of bits in the ICC_CTLR_EL1(S) and (NS) registers. QEMU chooses
to keep those bits in the cs->icc_ctlr_el1[] struct fields.
Unfortunately a missing '~' in the code to update the bits
in those fields meant that writing to ICC_CTLR_EL3 would corrupt
the ICC_CLTR_EL1 register values.

In ich_vmcr_write() we enforce "writes of BPR fields to less than

The current codebase is not specific about the endianess of the
fw_cfg 'file' entry 'reboot-timeout'.
Per docs/specs/fw_cfg.txt:
=== All Other Data Items ===
Please consult the QEMU source for the most up-to-date
and authoritative list of selector keys and their respective
items' purpose, format and writeability.
Checking the git history, this code was introduced in commit
ac05f34924, very similar to commit 3d3b8303c6 for the
'boot-menu-wait' entry, which explicitely use little-endian.
OVMF consumes 'boot-menu-wait' as little-endian, however it does
not consume 'reboot-timeout'.
Regarding the git history and OVMF use, we choose to explicit
'reboot-timeout' endianess as little-endian.

pci_bus_is_root() currently relies on a method in the PCIBusClass.
But it's always known if a PCI bus is a root bus when we create it, so
using a dynamic method is overkill.
This replaces it with an IS_ROOT bit in a new flags field, which is set on
root buses and otherwise clear. As a bonus this removes the special
is_root logic from pci_expander_bridge, since it already creates its bus
as a root bus.

about to call already have checks against the config space limit and
do the right thing. So, remove the redundant tests.

To build MCFG, two information is necessary:
* bus number
* base address
Abstract these two information to AcpiMcfgInfo so that build_mcfg and
build_mcfg_q35 will have the same declaration.

mcfg_start points to the start of MCFG table and is used in
build_header. While this information could be derived from mcfg.

Dummy table (with signature "QEMU") creation came from original SeaBIOS
codebase. And QEMU would have to keep it around if there were Q35 machine
that depended on keeping ACPI tables blob constant size. Luckily there
were no versioned Q35 machine types before commit:
(since 2.3) a1666142db acpi-build: make ROMs RAM blocks resizeable
which obsoleted need to keep ACPI tables blob the same size on source/destination.
Considering the 1st versioned machine is pc-q35-2.4, the dummy table
is not really necessary and it's safe to drop it without breaking
cross version migration in both directions unconditionally.

Since we now support the message VHOST_USER_GET_INFLIGHT_FD
and VHOST_USER_SET_INFLIGHT_FD. The backend is able to restart
safely because it can track inflight I/O in shared memory.
This patch allows qemu to reconnect the backend after
connection closed.

Currently, we use DRIVER_OK status bit to check whether guest
driver has started the device in virtio_vmstate_change(). But it's
not the case for virtio 1.0 transitional devices. If migration completes
between kicking virtqueue and setting VIRTIO_CONFIG_S_DRIVER_OK, guest
may be hung. So here we use started flag to check guest state instead.

A number of virtio devices (gpu, crypto, mouse, keyboard, tablet) only
support the virtio-1 (aka modern) mode. Currently if the user launches
QEMU, setting those devices to enable legacy mode, QEMU will silently
create them in modern mode, ignoring the user's (mistaken) request.
This patch introduces proper data validation so that an attempt to
configure a virtio-1-only devices in legacy mode gets reported as an
error to the user.
Checking this required introduction of a new field to explicitly track
what operating model is to be used for a device, separately from the
disable_modern and disable_legacy fields that record the user's
requested configuration.
