From bb9e14cfd0e8adc3e8a5a5d112cd7a4ca5c39472 Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Sat, 11 Jun 2022 20:20:59 +0800 Subject: [PATCH] imx: imx8mn_var_som: enable DM_SERIAL Enable CONFIG_DM_SERIAL. uart and its pinmux was already marked with u-boot,dm-spl. Move preloader_console_init after spl_init to make sure driver model work.
