From 07f9748f2255f7c157d55feccd12ff713ce255c6 Mon Sep 17 00:00:00 2001 From: Daisuke Nojiri Date: Thu, 1 Feb 2018 07:46:02 -0800 Subject: ec/google: Get OEM ID and SKU ID from EC This patch adds EC_CMD_GET_CROS_BOARD_INFO and two APIs to fetch OEM ID and SKU ID from cros EC. CBI abbreviates Cros Board Info. BUG=b:70294260 BRANCH=none TEST=Verify AP log shows expected OEM ID and SKU ID on Fizz.
