But this is normal for a non-embedded environment. If you don;t embed
it with the U-Boot image it will not be initialized after  installing
the  image  anyway  (because  it is not included), so there is little
sense initializing it at compile time.

There are several other options: in cases where  the  environment  is
directly  adjecent  to  the  U-Boot image (it looks as if the FADS is
such a configuration) you can "include" the environment, producing  a
bigger image which then contains an initialized environment.

It is up for the board maintainer to decide what he wants.

Best regards,
