Note that it's also part of the intel-1xxxx feature, which is basically
there for reusability - they were all together in a bunch of BSPs so I
moved them into a feature.  I'm wondering whether we want to break them
up or at least create a separate e100 feature.

It means that config option was never set or got turned off because of
unmet depencies.
