Running "saveenv" causes U-Boot to hang because of this overlap. Fix this problem by increasing the CONFIG_ENV_OFFSET size. Also, in order to prevent this same problem in the future, use CONFIG_BOARD_SIZE_LIMIT, which will detect the overlap in build-time. CONFIG_BOARD_SIZE_LIMIT does not accept math expressions, so declare CONFIG_ENV_OFFSET with its direct value instead.
