From 8aec32f6abd722b141d96bc095999efa76bd0327 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sat, 16 Jan 2021 14:52:26 -0700 Subject: cros_ec: Support reading EC features The EC can support a variety of features and provides a way to find out what is available. Add support for this. Also update the feature list to the lastest available while we are here.
