From 2e40ab1f215641c53d2c60baa347892d159cafc9 Mon Sep 17 00:00:00 2001 From: Ashok Reddy Soma Date: Fri, 22 Jul 2022 02:46:55 -0600 Subject: [PATCH] firmware: zynqmp: Load config overlay for core0 to pmufw Try loading pmufw config overlay for core0, if it doesn't return any error it means pmufw is accepting nodes for other IP's. Otherwise dont try to load config object for any other IP, just return from zynqmp_pmufw_node function.
