6 Enable recording of boot time while booting. To use it, insert
7 calls to bootstage_mark() with a suitable BOOTSTAGE_ID from
8 bootstage.h. Only a single entry is recorded for each ID. You can
9 give the entry a name with bootstage_mark_name(). You can also
10 record elapsed time in a particular stage using bootstage_start()
11 before starting and bootstage_accum() when finished. Bootstage will
