From 6be3490d4d751eaa4af3823d3fd6eacb55a4b9bf Mon Sep 17 00:00:00 2001 From: Paul Kocialkowski Date: Fri, 06 Nov 2015 13:10:44 -0500 Subject: Replace Chromebook mentions with CrOS, that is more generic Not all CrOS devices are Chromebooks (laptops) or run on ARM, not all RK3288 CrOS devices are Chromebooks, either. We want to support more CrOS devices, including some that are not Chromebooks, such as the ASUS Chromebit!
