That makes a certain amount of sense, I suppose, and would certainly
reduce the litter of new _FIRMWARE options, as well as the pointless
whining that some people like to repeat at _each_ patch when we default
them to 'N'. I could do it something like below...

What was the final conclusion on the need to add 'select FW_LOADER'?
Is that going to go away, too?
