2008-08-21 Joel Sherrill <joel.sherrill@oarcorp.com>

	* Makefile.am: Added bspclean.c and use shared bsppretaskinghook.c.
	* console/console.c: Added poll for char helper.
	* include/bsp.h: Add macro definitions for optional reset behavior.
	* startup/bspstart.c: Split out bsp_cleanup(). Clean up.
	* startup/bspclean.c: New file.  Not can press any key on normal
	shutdown to reset board when on MPC8313erdb.
