This patch adds a callback into the BootROM's provided High Assurance Boot (HAB) failsafe function when panicking i.e. the call is done without making use of stack. The HAB failsafe function allows a piece of software to call into the BootROM and place the processor into failsafe mode. Failsafe mode is a special mode which presents a serial download protocol interface over UART or USB at the time of writing. If the board has been set into secure mode, then only a signed binary can be used to recover the board. Thus failsafe gives a putatively secure method of performing a secure recovery over UART or USB.
