 Dear all,
I am studying Android power-on routine (including how many

 regarding this topic available? Thank you in advance.

You should turn on bootchart, which is supported in /init.
Documentation on this is available in system/core/init/README.BOOTCHART

There's a page describing how use bootchart with Android, at:
http://elinux.org/Using_Bootchart_on_Android

On that elinux page, there's a sample bootchart of cupcake in an emulator
(on a rather slow desktop system).

If other people have sample bootchart images, maybe they can upload
them to the wiki page?

It's not obvious to me which list that would be.  The only two that I see
that might be firmware-related are the kernel list and the developer list
(this one).  Is there one I'm missing?
