713    require a context switch from secure to non-secure or vice-versa:
721    The SPD service must save the system register context of the current
722    security state. It must then restore the system register context of the
742 exception level in the non-secure state. The former should save the SP context,

773    ``SPSR_EL3.DAIF`` bits in the secure CPU context. It sets ``x0`` to
