- * /dev/sci[0|1] for Hitachi SH 704X
- *
- * 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.
