If CONFIG_SPL_SERIAL_SUPPORT is not set, then the build will fail:
board/ti/am335x/built-in.o: In function `spl_start_uboot': board/ti/am335x/board.c:247: undefined reference to `serial_tstc' board/ti/am335x/board.c:247: undefined reference to `serial_getc'
Avoid the calls to the serial functions in that case.
