In general, the term does have a "fuzzy" meaning. But within the AMCC 
4xx processors, it does not. And we are talking about a command that 
would only be available to AMCC 4xx processors.

A command that's been in use on several U-Boot 4xx ports for some time.

It does actually allow you to set the boot ROM location, just FYI.

Of course. And I suppose I'm wasting energy typing since you have 
already made up your mind on the subject but no harm in trying.
