Supports turning system on and off via power button. Also added 'powerbtn' command, which sends a power button press of the specified duration, and deprecated the 'x86power s0' command, since pressing the power button is a more correct way of powering on/off the system. Note that current coreboot doesn't seem to boot reliably; when it fails, the x86 asks for S5 and then S0 a second later. It boots about every 3rd try. No indication this is due to the EC; the EC just was ignoring these requests until this CL. Signed-off-by: Randall Spangler <rspangler@chromium.org> BUG=chrome-os-partner:7851 TEST=reboot, 'powerbtn', system should power on 'powerbtn', system should power off 'powerbtn 5000', system should power off regardless of previous state press power button, system should power on press power button again, system should power off hold power button 8 sec, system should power off regardless of previous state Change-Id: I89f419553289b20c78a57bc8cb1699932b095aa1
- EC Lib
This wraps Blizzard driverlib and implements the EC chip interface defined
by Google. See below diagram for architecture.
