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 | |
57247d9c | 12 | add up all the accumulated time and report it. |
ee2b2434 SG |
13 | |
14 | Normally, IDs are defined in bootstage.h but a small number of | |
57247d9c | 15 | additional 'user' IDs can be used by passing BOOTSTAGE_ID_ALLOC |
ee2b2434 SG |
16 | as the ID. |

478 | With this option U-Boot will call arch_early_init_r() soon after | |
479 | relocation. Driver model is running by this point, and the cache | |
480 | is on. Note that board_early_init_r() is called first, if | |
481 | enabled. This can be used to set up architecture-specific devices. | |

483 | config ARCH_MISC_INIT |
484 | bool "Call arch-specific init after relocation, when console is ready" | |
485 | help | |
486 | With this option U-Boot will call arch_misc_init() after | |
487 | relocation to allow miscellaneous arch-dependent initialisation | |
488 | to be performed. This function should be defined by the board | |
489 | and will be called after the console is set up, after relocaiton. | |

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