I don't think mach-types.h is worth spending so much effort on it, and
coming up with another set of tools, incompatible to everything else
in the world.

I will not accept this. It willonly result in people adding entries
that have not been registered so they cause conflicts sooner or later.
We have been there before, and it did not work. I will not go back
there.

Right. But this should be no problem, as you can register your MACH_ID
as early as you want.

Just react in a pro-active way and register your machines as soon as
you start working on the hardware design, and everything is well.
