help

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

Calls to show_boot_progress() will also result in log entries but

Stash the bootstage information in the FDT. A root 'bootstage'
|
|
node is created with each bootstage id as a child. Each child
|
|
has a 'name' property and either 'mark' containing the
|
|
mark time in microseconds, or 'accum' containing the
|
|
accumulated time for that bootstage id in microseconds.
|
|
For example:
|
|
|
|
bootstage {

154 {

name = "board_init_f";
|

mark = <3575678>;

Note, defining the SUPPORT_RAW_INITRD allows user to supply

kernel with raw initrd images. The syntax is slightly different, the

address of the initrd must be augmented by it's size, in the following

format: "<initrd address>:<initrd size>".

With this option U-Boot will call arch_early_init_r() soon after
|
|
relocation. Driver model is running by this point, and the cache
|
|
is on. Note that board_early_init_r() is called first, if

With this option U-Boot will call arch_misc_init() after

Some boards need to perform initialisation as soon as possible

Some boards need to perform initialisation immediately before control

U-Boot calls last_stage_init() before the command-line interpreter is

started.
