description:
  The Texas Instruments Message Manager is a mailbox controller that has
  configurable queues selectable at SoC (System on Chip) integration. The
  Message manager is broken up into queues in different address regions
  that are called "proxies" - each instance is unidirectional and is
  instantiated at SoC integration level to indicate receive or transmit path.
