7. A non-transitory machine-readable medium including instructions, that when executed by a controller, cause the controller to:
receive a trust state message from a first computing device to supply an update to a second computing device;
designate, based on the trust state message, a signal state of a general-purpose input/output (GPIO) trust state signal asserted to the second computing device, wherein the signal state of the GPIO trust state signal indicates to the second computing device whether the first computing device is utilizing a trusted environment to verify the update; and
modify the state of the GPIO trust state signal responsive to receiving a close trusted update trust state message, wherein the close trusted update trust state message is issued from the first computing device via a nonvolatile embedded controller random-access memory (ECRAM), indicating the first computing device is ready to boot an operating system.
