From 49428d840323210433c96740545246296d65b3f2 Mon Sep 17 00:00:00 2001 From: Stefan Reinauer Date: Thu, 21 Feb 2013 15:48:37 -0800 Subject: [PATCH] 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) Change-Id: I03d00cf391bbb1a32f330793fe9058493e088571 Signed-off-by: Stefan Reinauer Reviewed-on: http://review.coreboot.org/2482 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.
