This hierachy contains support routines for the various

Various non BSP dependant support routines.
clock - Uses the 403 PIT (Programmable interval timer) to
generate RTEMS clock ticks.
console - Uses the 403 Internal serial port to do RTEMS
console I/O. Not ALL memebers of the 403 family
have this.
include - Currently empty
timer - Uses the 403 timebase register for timing
tests. Other PowerPCs have slightly different
timebase register definitions.
vectors - PowerPC 403 specific vector entry points.
Includes CPU dependant, application independant
handlres: alignment.
