Very good point.  This was just me, working on my chainsaw-free bubble,
who didn't realize the danger of the code! :)

But actually I have no idea how to detect what kind of daughter board is
connected.  Hopefully there is generic way of doing this in beagle
boards.  Otherwise the only way I can think of is to add a Kconfig
option for this... :/

I'll fix it.

Sure, I'll do that.  I just copied this from a previous patch to which
someone commented the same thing.  I just forgot to fix it before
submitting, because I got so excited when it worked :)

No, I certainly didn't.  I have already sent a v3 without that.
