Add a mechanism for sending messages to and receiving messages from the FW. The FW has fairly limited functionality, so the mechanism doesn't have to support high message rate. Use device mailbox registers to form two rings, one "to" and one "from" the device. The rings are just a convention between driver and FW, not a HW construct. We don't expect messages larger than 4k so use page-sized buffers.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
