- * running in secure state when an irq is fired (Mon_Irq_Handler), and in non-secure
- * state when a fiq interrupt is fired (Mon_Fiq_Handler).
- * They originate by the monitor irq/fiq vector and run in monitor mode,
- * ie in secure state.
- * It assumes the following, set at boot time, or wherever it needs:
- * SCR.FW == 0 and SCR.FIQ == 1 and SCR.IRQ == 0 in non-secure state,
- * ie, in non-secure state, FIQs are taken to monitor mode and IRQs locally
- * SCR.FW == 0 and SCR.FIQ == 0 and SCR.IRQ == 1 in secure state,
- * ie, in the secure-state, FIQs are taken locally and IRQs to monitor
- * MVBAR holds the address of the monitor vectors base.
- * The code and the stacks memory reside both in secure memory.
