What if the user interrupts auto-boot with a fel provided boot.scr

This is an interesting question which is more generic than just these
variable, i.e. it applies to some extent to "ipaddr" when someone does
"dhcp ; saveenv" too.
Grepping around to see if there was any special handling for ipaddr I
came across "Vendor Parameter Protection" in the top-level README as
well as "CONFIG_ENV_FLAGS_LIST_DEFAULT" (and _STATIC) and various
default settings in include/env_flags.h.
I think CONFIG_ENV_FLAGS_LIST_* are what we want, and we want fel* to
be flagged "r" for read only
Ah, yes that sounds exactly what we want, thanks for figuring that
out.
and perhaps given an appropriate type
(either "d" or "x" for decimal or hex respectively, I suppose).
Regards,
Hans
