Pit is yet-to-be-released and uses the Samsung Exynos5420 octa-core
(big.LITTLE) SoC.

I should note that although coreboot works quite well on this platform, the
product itself will ship with u-boot.

About 210ms for coreboot alone, another 330ms for the whole verified boot
stuff (~540ms total). This is slightly misleading since there is a small
binary blob (which is in the blobs repo) that is run before coreboot. We
can only use a timer which is initialized in coreboot's bootblock on this
SoC, so counting begins a few microseconds after coreboot begins.
