Various non BSP dependant support routines.

clock - Uses the MPC823 PIT (Programmable interval timer) to
	generate RTEMS clock ticks.
	The formula for calculating the timer value is the same 
	in the FADS860. I haven't tested its accuracy.

console_generic - Uses the MPC823 SMCs to to serial I/O
	Only tested through termios in polled mode. The code
	supports interrupt mode too, but it's not tested.

include - console.h: function declarations for console related functions

vectors - MPC823 specific vector entry points.
	Includes CPU dependant, application independant
	handlers: alignment.
