I agree. I personally like having real HW revision detection so it's
easy to change the board revision if/when mods are made to each of the
prototypes with solder blobs, and visually confirm the revision.
Maybe we should move it to GPA17/18 to avoid the EINTs, but we only
really gain if we end up using those EINTs for something else...
Freeing up the camera port for IO might be nice, but I think I'd rather
leave those lines as they are in gta02. Less mistakes for us to make!
I've not dug into the datasheet, but would doing something with gpa0-8
be less risky?
