That's correct. When you "select FOO", kconfig ignores the dependencies
that "config FOO" may have, so you have to manually propagate them.
That's a bit annoying, but we don't have (yet?) enough understanding of
kconfig internals to change that. Yann E. Morin is getting more and
more knowledge about kconfig internals, so I'm hoping it may happen
some day, but for now, we have to propagate those dependencies manually.
