What if the user interrupts auto-boot with a fel provided boot.scr and then does "saveenv" ?
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).
