not sure if this is where this sort of thing should be posted, but i
used one of my stock kernel scanning scripts on the current barebox
tree to locate any CONFIG variables that are defined in a Kconfig file
somewhere but never subsequently tested in a preprocessor directive,
and here's the output. (it would be trivial to run the other scripts
to locate more oddities.)
