From d59f62bbdabeb98f12896c6af0ef50cbf25e013f Mon Sep 17 00:00:00 2001 From: Hannah Williams Date: Fri, 5 May 2017 16:39:21 -0700 Subject: mainboard/intel/glkrvp: Add support for GLKRVP GLKRVP is a reference board for GLK SOC RVP1 has DDR4 and RVP2 has LPDDR4 RVP2 is enabled by default and CONFIG_IS_GLK_RVP_1 should be selected if building for RVP1 GLKRVP can work with internal Intel EC or external Chrome EC AIC. For internal EC, CONFIG_EC_GOOGLE_CHROMEEC will not be selected ( CONFIG_GLK_INTEL_EC should be selected for internal EC config) By default, CONFIG_GLK_CHROME_EC is selected for external ChromeEC AIC config.
