+ 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.
