boards that have Kconfig warnings on hello_world.

[pabigot]

Below is a list of boards that on current master produce Kconfig warnings when asked to build hello_world. Generated from something like:

for f in $(find boards -name '*_defconfig') ; do basename $f _defconfig; done \
  | sort \
  | uniq \
  | while read b ; do rm -rf build && echo $b && west build -b $b samples/hello_world 2>&1 | grep -i warning ; done \
  2>&1 | tee all-warn.log

@carlescufi @nashif fyi. Not sure if all of these would trigger CI errors. Some generate additional warnings.

[nashif]

none of those would trigger errors in CI, we have lots of kconfig warnings in many of the samples, those are being fixed slowly by ulf afaik.

[ulfalizer]

Those warnings are implemented in scripts/kconfig/kconfig.py and aren't turned into errors.

There's fewer of them than I thought at least. I'm a bit afraid of turning it into an error, because I suspect some samples might rely on turning on some option for all boards even though it only makes sense for some of them. Maybe some of those cases could be cleaned up though.
