I believe u-boot will do this for me.

I don't see what this actually gives us. Also there are different
versions of PBL out there so we'd have to cope with each of them. I
think we want to remain as independent as possible; use PBL to get
u-boot started and then ditch it.

Great. That would appear to be GPIO 4 then.

These are handled by the omap-keypad driver already.
