I managed to get really far in my boot process, as I can now try to

If you end up needing to make a change here, please reshuffle the logic,
so it becomes more streamlined:
#ifdef CONFIG_COLDFIRE
...
#elif defined(CONFIG_SUN3)

#endif

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
