Making them exclusive would be a step backwards.
More so, selecting both config option really shouldn't break
the build. If one expect a build break because only one of
the options can be enabled then clearly the dependency should
be used so that user can select only one option at a time.
Ack. There should be dependency in Kconfig so that user can select
either 8250 console(through Quad-uart for zoom2/zoom3) or OMAP-serial
Console(through OMAP UART's).
No. The drivers MUST handle co-existing. You can have a bunch of drivers
configured to be _potential_ consoles, which one will end up being used
depends on, among other things, the bootargs. But it should be allowed
to configure both 8250 and omap-serial at the same time.
