    22 * /dev/console for Hitachi SH 703X
    33 *
    4  * The SH doesn't have a designated console device. Therefore we "alias"
    5  * another device as /dev/console and revector all calls to /dev/console
    6  * to this device.
    7  *
    8  * This approach is similar to installing a sym-link from one device to
    9  * another device. If rtems once will support sym-links for devices files,
    10  * this implementation could be dropped.
    11  *
     4 * This driver installs an alternate device name (e.g. /dev/console for
     5 * the designated console device /dev/console.
