+ *  buf_empty -      This flag is set to FALSE by the GPP after it has output
+ *                  messages for the DSP. The DSP host driver sets it to
+ *                  TRUE after it has copied the messages.
+ *  post_swi -       Set to 1 by the GPP after it has written the messages,
+ *                  set the size, and set buf_empty to FALSE.
+ *                  The DSP Host driver uses SWI_andn of the post_swi field
+ *                  when a host interrupt occurs. The host driver clears
+ *                  this after posting the SWI.
+ *  size -          Number of messages to be read by the DSP.
+ *
+ *  For messages from the DSP:
+ *  buf_empty -      This flag is set to FALSE by the DSP after it has output
+ *                  messages for the GPP. The DPC on the GPP sets it to
+ *                  TRUE after it has copied the messages.
+ *  post_swi -       Set to 1 the DPC on the GPP after copying the messages.
