This looks like copy & paste logic from the m32r port (and history suggests this as well). Since building with hw & device support enabled leads to failures: sim/frv/devices.c: In function 'device_io_read_buffer': sim/frv/devices.c:39:15: error: 'UART_INCHAR_ADDR' undeclared (first use in this function) Delete it entirely. We leave device support in place as it is used to flush the scache.
