* @details
*
* The timer driver supports the Cortex A9 private timer.
*
* The timer driver supports the following features:
* - Normal mode and Auto reload mode
* - Interrupts (Interrupt handler is not provided in this driver. Application
* has to register it's own handler)
*
* <b> Initialization and Configuration </b>
*
* The device driver enables higher layer software (e.g., an application) to
* communicate with the Timer.
*
* XScuTimer_CfgInitialize() API is used to initialize the Timer. The
* user needs to first call the XScuTimer_LookupConfig() API which returns
* the Configuration structure pointer which is passed as a parameter to
* the XScuTimer_CfgInitialize() API.
*
* <b> Interrupts </b>
*
* The Timer hardware supports interrupts.
*
* This driver does not provide a Interrupt Service Routine (ISR) for the device.
* It is the responsibility of the application to provide one if needed. Refer to
* the interrupt example provided with this driver for details on using the
* Timer in interrupt mode.
*
* <b> Virtual Memory </b>
*
* This driver supports Virtual Memory. The RTOS is responsible for calculating
* the correct device base address in Virtual Memory space.
*
* <b> Threads </b>
*
* This driver is not thread safe. Any needs for threads or thread mutual
* exclusion must be satisfied by the layer above this driver.
*
* <b> Asserts </b>
*
* Asserts are used within all Xilinx drivers to enforce constraints on argument
* values. Asserts can be turned off on a system-wide basis by defining, at
* compile time, the NDEBUG identifier. By default, asserts are turned on and it
* is recommended that users leave asserts on during development.
*
* <b> Building the driver </b>
*
* The XScuTimer driver is composed of several source files. This allows the user
* to build and link only those parts of the driver that are necessary.
*
* <br><br>
*
* NOTE:
* The timer is not a part of the snoop control unit as indicated by the
* prefix "scu" in the name of the driver.
* It is an independent module in APU.
*

* 1.00a nm 03/10/10 First release
* 1.02a sg 07/17/12 Included xil_assert.h for CR 667947. This is an issue
* when the xstatus.h in the common driver overwrites
* the xstatus.h of the standalone BSP during the
* libgen.
* 2.1 sk 02/26/15 Modified the code for MISRA-C:2012 compliance.
