YMMV.

To protect myself from doing stupid things too  often.  To  allow  me
being  lazy like running "era all" without need to think where U-Boot
or the environment might be located on a board.

Because there simply *is* *no* policy at all.  Especially  not  in  a
one-size-fits-all  driver like cfi_flash which is what we are talking
about.

If you have special requirements please feel free to implement  these
in  your  board  specific code. But don't try to enforce your special
ideas of how things should be on everybody else.


Best regards,
