That's nothing against what I have said. Having as much flexibility you
need is great. We should support several method how to setup stuff and
it is up to user if this method is suitable for you or not and doing
these selection via Kconfig is the way we need to go.
For all these autodetection algorithms you have to be sure that it is
working fine on your platform based on testing.
