Gunyah is an open-source Type-1 hypervisor developed by Qualcomm. It
does not depend on any lower-privileged OS/kernel code for its core
functionality. This increases its security and can support a smaller
trusted computing based when compared to Type-2 hypervisors.

Add documentation describing the Gunyah hypervisor and the main
components of the Gunyah hypervisor which are of interest to Linux
virtualization development.

Is this the usual meaning of higher and lower? Seems backwards to me.

Hmm, I guess this x86 having ring 0 as most privileged and arm using EL3 as most
privileged. I'll switch to "more" and "less" privilege rather than implying
a numbering scheme.

I suspected that. Thanks for the change.
