This board has SPI flash, so storing env in SPI flash is probably a
better default. However, preferably the env should be stored/loaded from
the same device that TPL/SPL was loaded from.

What is your use case for being able to store the env? Personally, I have
never had a need for storing an env and use ENV_IS_NOWHERE on my boards.

Regards,
Jonas
