From 2c7ebf7778cf8afcec55ca418daba1e1d10075b7 Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Wed, 26 Jan 2022 12:25:23 -0600 Subject: [PATCH] imx: imx8mn_beacon: Fix USB booting The i.MX8M Nano can boot over USB using the boot ROM instead of adding extra code to SPL to support USB drivers, etc. However, when booting from USB, the environment doesnt' know where to load and causes a hang. Fix this hang by supporting CONFIG_ENV_IS_NOWHERE=y. It only falls back to this condition when booting from USB, so it does not impact MMC booting.
