From 79a43db93399cfc7825a908a03320677c52ef919 Mon Sep 17 00:00:00 2001 From: Daniel Baluta Date: Thu, 31 Mar 2022 13:32:37 +0300 Subject: [PATCH] remoteproc: imx_dsp_rproc: Make rsc_table optional There are cases when we want to test a simple "hello world" app on the DSP and we do not need a resource table. remoteproc core allows us having an optional rsc_table.
