I've tried and I don't see how to include functions to handle both MMC
and SF environment in the same binary with the current env code.

A workaround would be to use MMC to store env also on the MarSBoard but
as it is using the SPI flash as the boot source I would prefer to keep
the env in the SPI flash.
