From e7e768c08a09d09507a47d8e4127e7222d2241c8 Mon Sep 17 00:00:00 2001 From: Sheng-Liang Pan Date: Fri, 7 May 2021 18:47:46 +0800 Subject: chronicler: Initial EC image Create the initial EC image for the chronicler variant by copying the volteer reference board EC files into a new directory named for the variant. (Auto-Generated by create_initial_ec_image.sh version 1.5.0).
