[PATCH v2 edk2-platforms 0/8] Platform/ARM/Sgi: Add support for virtio network device

[Vijayenthiran Subramaniam]

Changes since v1:
- Rebased the series against latest edk2-platforms

This patch series adds support for virtio network controller found in ARM SGI
plaform's fast models. The first patch in this series restructure the
virtio device registration code to allow registration of additional virtio
devices. The second patch adds support for the virtio network device. The rest
of the patches update the ACPI tables to add an entry for the virtio network
device and corresponding PCDs for virtio block and network device.

[PATCH v2 edk2-platforms 1/8] Platform/ARM/SgiPkg: Restructure virtio device registration

[Vijayenthiran Subramaniam]

From: Daniil Egranov <daniil.egranov@arm.com>

SGI platforms support multiple virtio devices. So the existing code, that
supports registration of only the virtio disk, is restructured to
accommodate the registration of additional virtio devices.

In addition to this, PCDs to represent the virtio controller base and
address space size are introduced.
