Add support for Google's Chromebook Pixel
Ladies and gentlemen, I'm very happy to announce coreboot support for
the latest and greatest Google Chromebook: The Chromebook Pixel.
See the link below for more information on the Chromebook Pixel, and
its exciting specs:
http://www.google.com/intl/en/chrome/devices/chromebooks.html#pixel
The device is running coreboot and open source firmware on the EC
(see ChromeEC commit for more information on that exciting topic)
