[MinnowBoard] MinnowBoard MAX getting started with GPIO

[Peter Ogden]

I asked this exact question on IRC last week.

What I was told is you need to do is compile the kernel with the GPIO SYSFS
enabled.

I'm still very new to this myself, so I haven't been able to try this yet.
Hopefully that gives you a hit on what to search for.  I was googling
"compile linux kernel with gpio driver enabled".
