Yin Fengwei 7edf929a69 hv: trap vm0 write/read pm1a/pm1b registers
ACRN needs to trap the pm1a/pm1b written/read from VM0. So we
could know when should we put the system to S3.

We will have two path back to VM0:
 - S3 enter/exit sucess. Will reset VM0 and jump to VM0 wakeup vec
   with real mode
 - S3 enter/exit failed. Will return to the next instruction of
   pm1a/pm1b register writing. VM0 will read the pm1a/pm1b evt
   register to check whether it's waked up or not.

Embedded-Hypervisor
###################

This open source embedded hypervisor defines a software architecture for
running multiple software subsystems managed securely on a consolidated
system (by means of a virtual machine manager), and defines a reference
framework Device Model implementation for devices emulation

This embedded hypervisor is type-1 reference hypervisor, running
directly on the system hardware. It can be used for building software
defined cockpit (SDC) or In-Vehicle Experience (IVE) solutions running
on Intel Architecture Apollo Lake platforms. As a reference
implementation, it provides the basis for embedded hypervisor vendors to
build solutions with an open source reference I/O mediation solution,
and provides auto makers a reference software stack for SDC usage.

This embedded hypervisor is able to support both Linux* and Android* as
a Guest OS, managed by the hypervisor, where applications can run.

This embedded hypervisor is a partitioning hypervisor reference stack,
also suitable for non-automotive IoT & embedded device solutions. It
will be addressing the gap that currently exists between datacenter
hypervisors, hard partitioning hypervisors, and select industrial
applications.  Extending the scope of this open source embedded
hypervisor relies on the involvement of community developers like you!
