From dd874c80cdd2dd564465e2bf18e64ca31a5d9c51 Mon Sep 17 00:00:00 2001 From: Jeremy Soller Date: Tue, 5 Jan 2021 15:54:13 -0700 Subject: ec/system76/ec: Remove unused EC RAM fields These fields were originally added for compatibility with the proprietary ITE EC firmware, but the System76 EC firmware does not use them. Take the opportunity to document most of the fields as well.
