Don't be silly. Nobody wants an extra chip. Especially not one that is
programmable separately from the hardware. That way lies madness and
the usual firmware crazies.

It's not even what I asked for. I talked about discoverable buses. How
hard is that to understand? No extra chips, no eeprom, just a bus with
a notion of configuration cycles. It doesn't even have to be as
complicated as PCI, it could easily be a read-only model.

But no, every SoC designer out there seems to want to make their
hardware crap. Don't be surprised when I then call them out on the
fact. And don't bring up totally irrelevant issues that have nothing
to do with anything.

Is there a cost? Yes, it's a cost of good design and effort to try to
get it right. Usually that cost pays itself back over the years.
