All PIN() assignments in board/$BOARD/gpio.inc must be unique, since otherwise you're just creating duplicate names and table entries for the same core interrupt and may not be initializing things the way you think. BUG=none BRANCH=none TEST=make buildall; test on Cr50 hardware Also verified that the image size is exactly the same before an after this CL.
