Macros
#define	LEON3_IRQCTRL_ACQUIRE(_lock_context) rtems_interrupt_lock_acquire( &LEON3_IrqCtrl_Lock, _lock_context )
	Acquires the interrupt controller lock.

#define	LEON3_IRQCTRL_RELEASE(_lock_context) rtems_interrupt_lock_release( &LEON3_IrqCtrl_Lock, _lock_context )
	Releases the interrupt controller lock.

Functions
void	leon3_ext_irq_init (irqamp *regs)
	Initializes the interrupt controller for the boot processor.

Variables
uint32_t	LEON3_Cpu_Index
	This object provides the index of the boot processor.

rtems_interrupt_lock	LEON3_IrqCtrl_Lock
	This lock serializes the interrupt controller access.

irqamp *	LEON3_IrqCtrl_Regs
	This pointer provides the IRQ(A)MP register block address.

struct ambapp_dev *	LEON3_IrqCtrl_Adev
	This pointer provides the IRQ(A)MP device information block.

uint32_t	LEON3_IrqCtrl_EIrq
	This object provides the interrupt number used to multiplex extended interrupts or is zero if no extended interrupts are available.
