This basically allows to have completely separate U-Boot (TPL/SPL/U-Boot proper/environment) per storage medium which is convenient when working with recovery from SD-Card as one would just need to insert a properly configured SD-Card into the device to have access to their whole debug setup. No fallback mechanism is provided as to not dirty other storage medium environment by mistake. However, since arch_env_get_location() is called by env_init() which is part of the pre-relocation process, a valid, non-ENVL_UNKNOWN, value shall be returned otherwise the relocation fails with the following message: initcall sequence 00000000002866c0 failed at call 0000000000256b34 (err=-19) This valid, non-ENVL_UNKNOWN, value is ENVL_NOWHERE which requires to always select CONFIG_ENV_IS_NOWHERE otherwise this work-around does not work.
