  • Makefile.am, console/console.c, include/bsp.h: Use standardized bsp_cleanup() which can optionally print a message, poll for user to press key, and call bsp_reset(). Using this eliminates the various bsp_cleanup() implementations which had their own implementation and variety of string constants.
  • startup/bspreset.c: New file.
  • startup/bspclean.c: Removed.
  • Property mode set to 100644
