In this patch-set we're attempting to add boottime measurement
support to u-boot. A patch-set has already hit the kernel MLs
which intends to solve the other half of the puzzle.

This new tool allows an engineer to apply tags into key areas
around the bootloader, which are then passed to the Linux
kernel for processing and statistics analysis of full (bootloader
+ kernel) device booting.
