From d59eedc0e408565cb65eab46040bb1a07eaec315 Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Tue, 22 Jun 2021 14:01:48 +0800 Subject: remoteproc: imx_rproc: support i.MX8ULP i.MX8ULP is a new SoC with Ultra low power support, it has a Cortex-M33 core and two Cortex-A35 cores. We need to add new configuration because it could not reuse the previous i.MX7/8 configuration. i.MX8ULP M33 core is kicked by ROM, it is not under control of A35 core. So need to mark the method is IMX_RPROC_NONE.
