          Mailbox is a framework to control hardware communication between
          on-chip processors through queued messages and interrupt driven

Isn't this too generic?
Not all platforms, with a mailbox controller, use SCMI as the protocol.

Yikes! I agree Jassi, this looks super hack.

Yes indeed, I have still to rework this part of the series.

(@Jassi: I'm reworking this series starting from the work done by Peter up to
V3, since it needed some core SCMI transport rework to ease implememtation of
virtio-scmi transport)

Thanks,
Cristian
