Mmm. The other question I had about the system reset controller
is whether it's really purely hardware doing the "start secondary CPU",
or is it just a funny way of asking the system firmware to start
things, or is the stuff like the register for startup address
just a place to leave information that the system firmware
on the secondary CPU will read as part of its boot sequence?

Is there a datasheet available for this?
