You found tools/env/fw_env.c showing that this functionality is indeed
foreseen and used.
It is rather common to write to the U-Boot environment in projects for
example to switch to a new set of kernel+file system after an update
from within linux for the next boot.
Is this feedback enough?
Cheers
Detlev
