This adds the first few sysfs attributes for the Chrome OS EC. These
controls are made available under /sys/devices/virtual/chromeos/cros_ec
flashinfo - display current flash info
reboot - tell the EC to reboot in various ways
version - information about the EC software and hardware
Future changes will build on this to add additional controls.
From a root shell, you should be able to do things like this:
cd /sys/devices/virtual/chromeos/cros_ec
cat flashinfo
cat version
echo rw > reboot
cat version
echo ro > reboot
cat version
echo rw > reboot
cat version
echo cold > reboot
That last command will reboot the AP too.
