\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The _Watchdog_Nanoseconds_since_tick_handler() function caller does not take into account that the timer counter may wrap, underflow or overflow. Instead, the driver must take that into account. This GPTIMER DrvMgr driver patch makes use of the IRQ-Pending bit to determine if a underflow has happened. In that case a greater time than one tick is returned (even considering the function name..). The TLIB clock layer must also ACK the interrupt pending bit, otherwise we couldn't determine whether an IRQ is pending or if belongs to un old already handled tick IRQ. Note that this patch only fixes the DrvMgr GPTIMER driver and TLIB, the standard LEON3 GPTIMER driver still needs a fix.

*	LEON: GPTIMER driver, Timer Library and System Clock for LEON3	Daniel Hellstrom	2015-04-17	1	-0/+264
	With this patch the LEON family can access the GRLIB GPTIMER using the Timer library (TLIB). A System Clock driver instead of BSP/clock/ck_init.c is provided using the TLIB. The classic clock driver is split in two parts, clock driver and timer driver. The BSPs need only to fullfill the timer interface instead of the clock interface. Currently only LEON3 uses it. The LEON2 Timer is not ported to TLIB. The GPTIMER driver is implemented using the Driver Manager, so the System Clock Driver is at this point only suitable for LEON3 when the driver manager is initialized during BSP startup. When the DrvMgr is not initialized during startup the standard BSP/clock dirver is used. LEON2 sometimes also needs to access GPTIMER when a off-chip GRLIB AMBA systems is connected, for example AMBA-over-PCI.
