Tao Yuhong 84752ab229 Fix: HV: VM OS failed to assign new address to pci-vuart BARs
When wrong BAR address is set for pci-vuart, OS may assign a
new BAR address to it. Pci-vuart BAR can't be reprogrammed,
for its wrong fixed value. That can may because pci_vbar.fixed and
pci_vbar.type has overlap in abstraction, pci_vbar.fixed
has a confusing name, pci_vbar.type has PCIBAR_MEM64HI which is not
really a type of pci BARs.
So replace pci_vbar.type with pci_vbar.is_mem64hi, and change
pci_vbar.fixed to an union type with new name pci_vbar.bar_type.

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.
