I did wonder if that made sense given that this is not a user selectable option so I'm not sure if the help will ever be visible, but I see that we do this sort of thing in Kconfig.kcsan and Kconfig.kgdb.

Fair enough. I'll pull it out of this file and look for a good place to put the information in arch/powerpc in a later patch/series. Kind regards, Daniel
