From 19237f6a338fa1c593867d8dfda1edcd376878af Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Thu, 18 Sep 2014 12:56:04 -0700 Subject: [PATCH] samus: Ensure PD controller is in RO mode for recovery In order to not break FAFT, and to have a quicker recovery mode boot, reboot the PD controller into RO image in romstage. This is done before the EC since rebooting the EC into RO will also reboot the host. BUG=chrome-os-partner:30079 BRANCH=none TEST=boot samus EVT into recovery with 'dut-control power_state:rec' and ensure that the PD controller is rebooted to RO in romstage.
