+ * /dev/console for Hitachi SH 703X
+ *
+ * The SH doesn't have a designated console device. Therefore we "alias" 
+ * another device as /dev/console and revector all calls to /dev/console 
+ * to this device.
+ *
+ * This approach is similar to installing a sym-link from one device to 
+ * another device. If rtems once will support sym-links for devices files, 
+ * this implementation could be dropped.
