From 3ab34bc028e532f5b748104bd65392a575608411 Mon Sep 17 00:00:00 2001 From: Keerthy Date: Wed, 12 Feb 2020 13:55:04 +0530 Subject: arm: k3: Add support for loading non linux remote cores Add MAIN domain R5FSS0 remoteproc support from spl. This enables loading the elf firmware in SPL and starting the remotecore. In order to start the core, there should be a file with path "/lib/firmware/j7-main-r5f0_0-fw" under filesystem of respective boot mode.
