We were going straight to S5. When the PCH first goes into S5 after power-loss, it decides to boot for some reason. So, stay in G3. Still exit G3 if waking from hibernate or if the power button is pressed when the EC boots on a power-on reset. BUG=chrome-os-partner:10239 TEST=manual 1) Unplug battery and AC power. Plug in AC power. System does not boot. 2) Press power button. System boots now. 3) From console, 'hibernate 10'. Close and open lid. System boots. 4) From console, 'hibernate 10'. Press power button. System boots. 5) Hold power+esc+refresh. System boots into recovery. 6) Hold power+esc. EC reboots. Release esc. System stays off. 7) Unplug battery and AC power. Plug in AC power while holding power button. System boots.

- EC Lib
This wraps Blizzard driverlib and implements the EC chip interface defined
by Google. See below diagram for architecture.

---- chip interface ---- The interface is defined in
src/platform/ec/chip_interface/*.
