/*
|
||||
* /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.
