	  remote processor framework.

	  You want to say y here in order to enable AMP
	  use-cases to run on your platform (multimedia codecs are
	  offloaded to remote DSP processors using this framework).

	  This module controls the name of the firmware file that gets
	  loaded on the DSP.  This file must reside in the /lib/firmware
	  directory.  It can be specified via the module parameter
	  da8xx_fw_name=<filename>, and if not specified will default to
	  "rproc-dsp-fw".

	  It's safe to say n here if you're not interested in multimedia
	  offloading.
