From 107c167419e75213e078e4f2468c0f2f55fdd11a Mon Sep 17 00:00:00 2001 From: Simon Trimmer Date: Mon, 20 Mar 2023 11:22:40 +0000 Subject: firmware: cs_dsp: Support DSPs that don't require firmware download When a DSP can self-boot from ROM it is not necessary to download firmware during the powering up sequence. A DSP that required firmware download would fail in a previous configuration step if firmware was not available.
