c - Profiling u-Boot/Kernel boot sequence -


I outline the booting process of the power PC board, what is the easiest way to profile the booting sequence?

My first idea is to modify the U-boot / kernel code printf / printk (using the Realtime Tool as reference) and print them on the console. However, printing them on the console can only affect the timing.

Any thoughts?

Regards, Robert.
