bsppost.c

RTEMS (Real-Time Executive for Multiprocessor Systems) is a free open source real-time operating sys

/*
 *  This is a basic BSP post driver hook. 
 *
 * After drivers are setup, register some "filenames"
 * and open stdin, stdout, stderr files
 *
 * Newlib will automatically associate the files with these
 * (it hardcodes the numbers)
