Zhou, Wu 32cb5954f2 hv: refine the hard-coded GPA SSRAM area size
Using the SSRAM area size extracted by config_tools, the patch changes
the hard-coded GPA SSRAM area size to its actual size, so that
pre-launched VMs can support large(>8MB) SSRAM area.

When booting service VM, the SSRAM area has to be removed from Service
VM's mem space, because they are passed-through to the pre-rt VM. The
code was bugged since it was using the SSRAM area's GPA in the pre-rt
VM. Changed it to GPA in Service VM.

Tracked-On: #7212

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.
