2191 +   The Mini RoboMind is a small board based on the 68332 microcontroller
2192 +designed and build by Mark Castelluccio.  For details, see:

2196 +   This BSP was ported from the efi332 BSP by Matt Cross (profesor@gweep.net),
2197 +the efi332 BSP was written by John S Gwynne.
2198 +
2199 +TODO:
2200 +=====
2201 +- integrate the interrupt driven stdin/stdout into RTEMS to (a) reduce
2202 +  the interrupt priority and (2) to prevent it from blocking.
2203 +- add a timer driver for the tmtest set.

2286 +* Desc:     This file contains the console IO routines for the SCI port.
2287 +*           There are two interfaces in this module. One is for the rtems
2288 +*           termios/console code and the other is a device driver interface.
2289 +*           This module works together with the termio module which is
2290 +*           sometimes referred to as the "line disciplines" which implements
2291 +*           terminal i/o processing like tabs, backspaces, and newlines.
2292 +*           The rtems printf uses interrupt io and the rtems printk routine
2293 +*           uses polled io which is better for debugging.
