From eded500e3cb2d671e18fe6af389bf5b1769dda15 Mon Sep 17 00:00:00 2001 From: Sam McNally Date: Wed, 4 Mar 2020 16:08:06 +1100 Subject: security/vboot: Support enabling EC EFS with EC software sync If the ChromeOS EC uses EC early firmware selection (EFS), the AP vboot build must also enable EC EFS. Add an option to control this, passing it through to vboot.
