+ * dv-tx3904sio.c (tx3904sio_io_write_buffer): Use write value as a mask
+ to clear status bits in sdisr register. This is how the hardware works.
+
+ * interp.c (sim_open): Added more memory aliases for jmr3904 hardware
+ being used by cygmon.

* interp.c (decode_coproc): Correctly handle DMFC0 and DMTC0
