From d1215269a7bc9b3df82548a7ebdb0e468b18e1df Mon Sep 17 00:00:00 2001 From: Keith Short Date: Tue, 15 Jan 2019 10:32:22 -0700 Subject: src/mainboard/google/sarien: query recovery mode from Cr50 On the Sarien/Arcada platforms, the EC is not trusted to provide the state of the ESC+REFRESH+PWR recovery combination. On these platforms the Cr50 latches the state of REFRESH+PWR for use as the recovery mode key combination.
