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 and perhaps given an appropriate type (either "d" or "x" for decimal or hex respectively, I suppose).
