CC and CC3D boards share the same FW image. This is accomplished by checking the BOARD_REVISION field in the board_info_blob that is stored in the BL partition in flash as we init the FW. Make sure that the BU image only writes a BL image that has the same BOARD_TYPE and BOARD_REVISION fields in the embedded image as the ones currently in flash on the board. This ensures that we never write a CC3D BL image onto a CC board and vice versa. This check should prevent "bricking" a board.
