Boottime is a tool which can be used for full system booting time measurement. Bootloader boot time is passed to the kernel component though ATAGS. The kernel-side driver then uses this information to provide full system boot time diagnostics though debugfs.
Based heavily on the original driver by Jonas Aaberg.

Did you take a look at bootstage, which seems at least on the surface to provide a similar mechanism? This passes the information to the kernel through a device tree, or worse case a 'stash area'.
