dongshen 0ac2e21f20 hv: add support to assign 3rd non-contiguous HPA regions for logical partition scenario
Currently acrn supports 2 non-contiguous HPA regions (HPA1 and HPA2), extend
the code to support 3rd non-contiguous HPA region (HPA3) for logical partition scenario
(hybrid scenario is not supported)

To keep things simple, current design has the following assumptions for
ve820 and ept mapping:
 1. HPA2 will always be placed after HPA1
 2. HPA3 will always be placed after HPA2
 3. HPA1/HPA2/HPA3 don’t share a single ve820 entry.
  (Create multiple entries if needed but not shared)

ACRN Hypervisor
###############

The open source `Project ACRN`_ defines a device hypervisor reference stack and
an architecture for running multiple software subsystems, managed securely, on
a consolidated system by means of a virtual machine manager. It also defines a
reference framework implementation for virtual device emulation, called the
"ACRN Device Model".

The ACRN Hypervisor is a Type 1 reference hypervisor stack, running directly on
the bare-metal hardware, and is suitable for a variety of IoT and embedded
device solutions. The ACRN hypervisor addresses the gap that currently exists
between datacenter hypervisors, and hard partitioning hypervisors. The ACRN
hypervisor architecture partitions the system into different functional
domains, with carefully selected guest OS sharing optimizations for IoT and
embedded devices.

You can find out more about Project ACRN on the `Project ACRN documentation`_
website.
