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.
