CONFIG_CMD_BOOTSTAGE
|
||||
Add a 'bootstage' command which supports printing a report
|
||||
and un/stashing of bootstage data.
|
||||
|
||||
CONFIG_BOOTSTAGE_FDT
|
||||
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 microsecond, or 'accum' containing the
|
||||
accumulated time for that bootstage id in microseconds.
|
||||
For example:
|
||||
|
||||
bootstage {
|
||||
154 {
|
||||
name = "board_init_f";
|
||||
mark = <3575678>;
|
||||
};
|
||||
170 {
|
||||
name = "lcd";
|
||||
accum = <33482>;
|
||||
};
|
||||
};
|
||||
|
||||
Code in the Linux kernel can find this in /proc/devicetree.
