While a couple of the Haswell-based ChromeBooks have been added to upstream coreboot, but have not heard of anyone with them actually running yet. I know John Lewis had tried to get the HP ChromeBook 14 (falco) going but was not successful (though he does have the Chromium/falco branch working), and I assume the same is true for the Acer C720 (peppy) too, as they are nearly identical. Looking at it briefly, I'd suspect the issues are related to the display init or Google's EC, but haven't had a chance to play with one myself yet.
I have upstream coreboot running on the Haswell-based Asus ChromeBox (panther), and have submitted patches for it, but they have not yet been accepted/merged in. Also works for the nearly-identical HP ChromeBox (zako). I can throw my branch up on github in the meantime if would be useful, but that's where I'd recommend starting (vs the ChromeBooks).
cheers, Matt

As always, when doing a new board, get a system that is known to work with coreboot and has your chipset in it. You should get several (never just one!) of the haswell chromebooks, build coreboot, make sure you can make it all work, then try the port to your board.

My advice if you're working with those chromebooks is to start with the chromeos tree, not the upstream.
