 502           Enable recording of boot time while booting. To use it, insert
 503           calls to bootstage_mark() with a suitable BOOTSTAGE_ID from
 504           bootstage.h. Only a single entry is recorded for each ID. You can
 505           give the entry a name with bootstage_mark_name(). You can also
 506           record elapsed time in a particular stage using bootstage_start()
 507           before starting and bootstage_accum() when finished. Bootstage will
 508           add up all the accumated time and report it.
 509
 510           Normally, IDs are defined in bootstage.h but a small number of
 511           additional 'user' IDs can be used but passing BOOTSTAGE_ID_ALLOC
 512           as the ID.

 580           Some OSes do not support device tree. Bootstage can instead write
 581           the boot timing information in a binary format at a given address.
 582           This happens through a call to bootstage_stash(), typically in
 583           the CPU's cleanup_before_linux() function. You can use the
 584           'bootstage stash' and 'bootstage unstash' commands to do this on
