Note that this is a big security hole and should be removed after we complete the EC autoupdate mechanism and vboot code. To full update EC firmware on proto 1.0, we need a manual way to switch EC running on RO/RW. This CL implements the LPC command. BUG=chrome-os-partner:8415 TEST=on proto 0.5. ectool reboot_ec RW_A # EC boots to RW A ectool reboot_ec RO # EC boots to RO Change-Id: Ibf050328bc4e3d2c6d72bfc478d6334f11f0eb46
