 517           calls to bootstage_mark() with a suitable BOOTSTAGE_ID from

 520           record elapsed time in a particular stage using bootstage_start()

 522           add up all the accumated time and report it.

 596           This happens through a call to bootstage_stash(), typically in
 597           the CPU's cleanup_before_linux() function. You can use the
