* Added full support for MPC505.
	* mpc505/ictrl: New directory.
	* configure.in, mpc505/Makefile.am: Modified to reflect ictrl addition.
	* mpc505/ictrl/.cvsignore, mpc505/ictrl/Makefile.am,
	mpc505/ictrl/ictrl.c, mpc505/ictrl/ictrl.h: New files.
	* mpc505/timer/timer.c: Use <rtems.h>, not "rtems.h".
	* mpc505/vectors/Makefile.am: alignment exception handler now included.
	* mpc505/vectors/vectors.S: Now use constants for exception numbers.
	* old_exception_processing/ppc_offs.h: New file.
	* old_exception_processing/Makefile.am: Account for ppc_offs.h.
	* old_exception_processing/cpu.h: Make Nest and Disable levels volatile.
	* old_exception_processing/cpu_asm.S: Offsets moved to ppc_offs.h.
