Some platform doesn't use CPU(HOST)/Device 1:1 mapping for PCI Bus.
But PCI IO doesn't have interface to tell caller (device driver)
whether the address returned by GetBarAttributes() is HOST address
or device address.
UEFI Spec 2.6 addresses this issue by clarifying the address returned
is HOST address and caller can use AddrTranslationOffset to calculate
the device address.

VirtioLib provides an API for simple, synchronous (request/response-style)
virtio communication. The guest driver builds one descriptor chain, link
for link, with VirtioPrepare() and VirtioAppendDesc(), then submits the
chain, and awaits the processing, with VirtioFlush().
The descriptor chain is always built at the beginning of the descriptor
area, with the head descriptor having descriptor index 0.
In order to submit the descriptor chain to the host, the guest always
pushes a new "available element" to the Available Ring, in genuine
queue-like fashion, with the new element referencing the head descriptor
(which always has index 0, see above).
In turn, after processing, the host always pushes a new "used element" to
the Used Ring, in genuine queue-like fashion, with the new element
referencing the head descriptor of the chain that was just processed. The
same element also reports the number of bytes that the host wrote,
consecutively across the host-writeable buffers that were linked by the
descriptors.
(See "OvmfPkg/VirtioNetDxe/TechNotes.txt" for a diagram about the
descriptor area and the rings.)
Because at most one descriptor chain can be in flight with VirtioLib at
any time,
- the Available Ring and the Used Ring proceed in lock-step,
- and the head descriptor that the new "available" and "used" elements can
ever reference has index 0.
Based on the above, we can modify VirtioFlush() to return the number of
bytes written by the host across the descriptor chain. The virtio-block
and virtio-scsi drivers don't care (they have other ways to parse the data
produced by the host), while the virtio-net driver doesn't use
VirtioFlush() at all (it employs VirtioLib only to set up its rings).
However, the virtio entropy device, to be covered in the upcoming
patches, reports the amount of randomness produced by the host only
through this quantity.

AARCH64 systems never require compatibility with legacy ACPI OSes, and

So add a PCD PcdAcpiExposedTableVersions containing a bitmask describing
which ACPI versions are targeted, and wire it up it up to the memory
allocation calls in AcpiTableDxe/AcpiTableProtocol.c. I.e., if ACPI v1.0b
is not among the supported versions, the memory allocations are not limited
to 4 GB, and only table types that carry 64-bit addresses are emitted.
Note that this will inhibit the publishing of any tables that carry only
32-bit addresses, i.e., RSDPv1, RSDTv1 and RSDTv3.
