Looks like this can happen only when E500 is not selected. But what kind of CPU do we have if it's not a E500 ? AFAICS in cputable.c, if not a PPC32 and not a BOOK3S_64 is must be a E500 otherwise there's just no CPU. Should we make Kconfig stricter instead to avoid the Robot selecting a crazy config ?
