From: Peng Fan <peng.fan@nxp.com> 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. Signed-off-by: Peng Fan <peng.fan@nxp.com> --- drivers/remoteproc/imx_rproc.c | 13 +++++++++++++ 1 file changed, 13 insertions(+)
