Data Structures
struct	leon3_timecounter
	Represents the LEON3-specific timecounter. More...

Macros
#define	LEON3_REG_CACHE_CTRL_FI   0x00200000U
	This constant represents the flush instruction cache flag of the LEON cache control register.
#define	LEON3_REG_CACHE_CTRL_DS   0x00800000U
	This constant represents the data cache snooping enable flag of the LEON cache control register.
#define	LEON3_CLOCK_INDEX   0
	This constant defines the index of the GPTIMER timer used by the clock driver.
#define	LEON3_COUNTER_GPTIMER_INDEX   ( LEON3_CLOCK_INDEX + 1 )
	This constant defines the index of the GPTIMER timer used by the CPU counter if the CPU counter uses the GPTIMER.
#define	LEON3_GPTIMER_0_FREQUENCY_SET_BY_BOOT_LOADER   1000000
	This constant defines the frequency set by the boot loader of the first GPTIMER instance.

Functions
RTEMS_NO_RETURN void	leon3_power_down_loop (void)
	Sets asr19 to zero to enter the power-down mode of the processor in an infinite loop.

Variables
int	leon3_timer_core_index
	This object lets the user override which on-chip GPTIMER core will be used for system clock timer.
unsigned int	leon3_timer_prescaler
	This object lets the user override system clock timer prescaler.
gptimer *	LEON3_Timer_Regs
	This pointer provides the GPTIMER register block address.
struct ambapp_dev *	LEON3_Timer_Adev
	This pointer provides the GPTIMER device information block.
apbuart *	leon3_debug_uart
	This pointer provides the debug APBUART register block address.
leon3_timecounter	leon3_timecounter_instance
	Provides the LEON3-specific timecounter.
