These were kernel config options so I reached out to Justin for advice. He
gave me great advice by pointing me here, where I'll come in the future for
requests like this.

In hindsight the config options are related to an ARM device, so it would have
been good to start here.

That's good news, but the way you delivered the news makes me feel really dumb.

I'm not an expert in these topics and what is obvious to you isn't obvious to me
or a lot of people. I was trying to do some due diligence up front for a board I'd
like to purchase and run my favorite distribution on. I found where someone running
Arch needed these kernel config options set so I asked our resident kernel expert about
them.

Again, thanks for assuming I'm not following the process on purpose or being dumb
for not knowing the proper place to go. It makes me feel good to know there's so
much support for people who are looking to learn how to contribute and be part of
this community.
