That came from Al Borchers when he provided the "serial" gadget
driver. It helped clean up the preceding Config.in.  I don't know
precisely how he landed with that solution, likely something to
do with "undefined" dependencies interpreted (wrongly) as "true".

In what way was that problematic for you?

Agreed that some of the controller drivers might fit better as
"dep_tristate": net2280 and goku_udc depending on PCI; pxa2xx and
superh UDCs depending on those arch symbols.

On the other hand, see the updated Config.in below (more drivers
than 2.4.23-rc5):  it works with "menuconfig" and "config", on
x86 and ARM, and correctly prevents configuring both PCI-based
controllers; but I'd not say "better" because it breaks rudely
on "xconfig" (all those settings disabled).

Seems incorrect; if ZERO is statically linked, ETH must not be linked
either statically or dynamically.  (And so on for the other drivers.)

There may be a nice solution to these problems within the Config.in
constraints, but I don't think we've found one yet.
