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

463 to do this.

470 help
471 With this option U-Boot will call arch_early_init_r() soon after
472 relocation. Driver model is running by this point, and the cache
473 is on. Note that board_early_init_r() is called first, if
474 enabled. This can be used to set up architecture-specific devices.

477 bool "Call arch-specific init after relocation, when console is ready"
478 help
479 With this option U-Boot will call arch_misc_init() after
480 relocation to allow miscellaneous arch-dependent initialisation
481 to be performed. This function should be defined by the board
482 and will be called after the console is set up, after relocaiton.

485 bool "Call board-specific init before relocation"
486 default y if X86
487 help
488 Some boards need to perform initialisation as soon as possible
489 after boot. With this option, U-Boot calls board_early_init_f()
490 after driver model is ready in the pre-relocation init sequence.
491 Note that the normal serial console is not yet set up, but the
492 debug UART will be available if enabled.
