developers at Google started upstreaming their patches for their new devices. For example the boards Falco, Peppy, Pit and Slippy are now in the coreboot repository. Big thanks for that.
Slippy is a reference board that can't be bought. Peppy is the Acer C720 Falco is the HP Chromebook 14.
Those 3 are all haswell.
So what are Pit and Bolt? Can those be bought?
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.
If you have questions about anything in particular can provide more insight.
I’d be very much interested in timing data and comparison to older systems.
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.
