    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.<br>
    <br>
    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).<br>
