Fei Li ab4e19d0be hv: vPCI: fix large bar base update
The current code would write 'BAR address & size_maks' into PCIe virtual
BAR before updating the virtual BAR's base address when guest writing a
PCIe device's BAR. If the size of a PCIe device's BAR is larger than 4G,
the low 32 bits size_mask for this 64 bits BAR is zero. When ACRN updating
the virtual BAR's base address, the low 32 bits sizing information would
be lost.

This patch saves whether a BAR writing is sizing or not before updating the
virtual BAR's base address.

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.
