Hmm, do you mean that the time measured did not include invoking the
boot menu ? Or are you using a special configuration where the boot
menu functionality has been removed ? When booting from NAND, the
boot menu is only entered when you explicitly invoke it (by holding
down AUX). It is only explicitly brought up when booting from NOR.

This time is spent by u-boot's board bring-up (not entirely sure
why this has to take so long) and the check whether POWER is still
held (about 1-2 seconds), and whether AUX is being pressed.
