[Changes since v10]
Fixed macOS build issue. Changed imports to not be linux-specific.
[Changes since v9]
More cleanup and fixes based on suggestions from Peter Maydell
(peter.maydell@linaro.org) suggestions.
[Changes since v8]
Suggestions and Fixes from Peter Maydell (peter.maydell@linaro.org),
also cleaned up changes so nothing is deleted in a later patch that was
added in an earlier patch. Patch count decresed by 1 because this cleanup
led to one of the patches being irrelevant.
[Changes since v7]
Fixed patch 4 declaration of new NIC based on comments by Peter Maydell
(peter.maydell@linaro.org)
[Changes since v6]
Remove the Change-Ids from the commit messages.
[Changes since v5]
Undid remove of some qtests that seem to have been caused by a merge
conflict.
[Changes since v4]
Added Signed-off-by tag and fixed patch 4 commit message as suggested by
Peter Maydell (peter.maydell@linaro.org)
[Changes since v3]
Fixed comments from Hao Wu (wuhaotsh@google.com)
[Changes since v2]
Fixed bugs related to the RC functionality of the GMAC. Added and
squashed patches related to that.
[Changes since v1]
Fixed some errors in formatting.
Fixed a merge error that I didn't see in v1.
Removed Nuvoton 8xx references since that is a separate patch set.
[Original Cover]
Creates NPI Mailbox Module with data verification for read and write (internal and external),
wiring to the Nuvoton SoC, and QTests.
Also creates the GMAC Networking Module. Implements read and write functionalities with cooresponding descriptors
and registers. Also includes QTests for the different functionalities.

The PCI Mailbox Module is a high-bandwidth communcation module
between a Nuvoton BMC and CPU. It features 16KB RAM that are both
accessible by the BMC and core CPU. and supports interrupt for
both sides.
This patch implements the BMC side of the PCI mailbox module.
Communication with the core CPU is emulated via a chardev and
will be in a follow-up patch.

- Implementation of Receive function for packets
- Implementation for reading and writing from and to descriptors in
memory for Rx
When RX starts, we need to flush the queued packets so that they
can be received by the GMAC device. Without this it won't work
with TAP NIC device.
When RX descriptor list is full, it returns a DMA_STATUS for
software to handle it. But there's no way to indicate the software has
handled all RX descriptors and the whole pipeline stalls.
We do something similar to NPCM7XX EMC to handle this case.
1. Return packet size when RX descriptor is full, effectively dropping
these packets in such a case.
2. When software clears RX descriptor full bit, continue receiving
further packets by flushing QEMU packet queue.
