Anyone got any opinions in the new Kconfig-world regarding whether it is
more or less appropriate to use the help section of the Kconfig file vs.
the README file?

...and only now do I notice that the first two of the three options
mentioned above are already documented in the Kconfig and the third
(PSCI) isn't a Kconfig option (yet?) so there's no ambiguity about where
it should be put.

I also just noticed that the README says "Later we will add a
configuration tool - probably similar to or even identical to what's
used for the Linux kernel".
