	  When selected, the driver supports "asynchronous" command

	  Location of the host-writable inbox window within the

	  Location of the "outbox" region for SOF IPC3/4 message
	  within the pre-existing window 0 (this is not the same as
	  the HP_SRAM_RESERVE region used for INBOX_OFFSET).  This
	  location must be synchronized with host driver and SOF
	  source code (where it must equal SRAM_SW_REG_SIZE).  Be
	  careful.

	  Protocol variant.  When true, the first four bytes of a
	  message are passed in the cAVS IDR/TDR register pair instead
	  of in the SRAM window.  Only available on cAVS 1.8+.
