commit e7a7e8fc1206a8f5e5a9e3809c4a57356d0f751a Author: Duncan Laurie dlaurie@chromium.org Date: Thu Sep 18 12:56:04 2014 -0700
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.
