Emergency key erase from gpio pin

[theotherjenkutler]

It would be handy to have the ability to erase flash keys or the entire flash of the device in order to keep the system secure. I'm thinking a GPIO pin could be configured to flash erase on high or low, alternately some kind of command to erase flash via admin control to a remote node. Both would be great. In any case we appreciate what you do. Thank you for making something so great!
