Gunyah is an open-source Type-1 hypervisor, that is currently supported on ARM64
architecture. Source code for it can be obtained from:

https://github.com/quic/gunyah-hypervisor

This patch series adds support for Gunyah hypervisor via a new
accelerator option, 'gunyah'. This patch series is based on the Linux kernel's
Gunyah driver, which is being actively developed and not yet merged upstream
[1].

This patch series is thus *NOT YET READY* for merge. Early version of this patch
is being published to solicit comments from Qemu community.

This patch has been tested with the open-source version of Gunyah hypervisor.
Instructions to build hypervisor and test this patch are provided in this
patch series.

Changes in v1:

* Fixed SMP boot issues
* Addressed comments received for previous version (v0) of the patches series

Limitations:

Confidential guests (or protected VMs) are not yet supported.

Prior version, v0, of this patch can be referenced at:
