  • 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.
  • Property mode set to 100644
