When trying to boot via USB on i.MX8MN it is necessary to specify the U-Boot environment location, otherwise the boot process simply hangs.
Specify the environment location when booting from USB.
Tested on a imx8mn-evk.
Suggested-by: Michael Nazzareno Trimarchi michael@amarulasolutions.com Signed-off-by: Fabio Estevam festevam@denx.de --- Changes since v2: - Handle explicitly the CONFIG_ENV_IS_NOWHERE case and return ENVL_UNKNOWN as fallback (Marek).
