*
* The Xilinx XMpmc driver supports the following functionality in the Xilinx
* Multi-Port Memory Controller (MPMC), a soft IP core designed for Xilinx FPGAs:
* 		- Error Correction Code (ECC) capability
*		- Performance Monitoring
*		- Static PHY
*
* The device driver is not necessary for the MPMC device unless one of the
* three functionalities is enabled in the MPMC device.
*
* This header file contains the interfaces for the MPMC device driver.
*
* ECC is a mode that detects and corrects single memory errors and detects the
* double memory errors. The XMpmc device driver provides the following abilities
* for ECC:
*  - Enable and Disable ECC mode in Read logic/Write logic or both.
*  - Enable and Disable interrupts for specific ECC errors.
*  - Error injection for testing of ECC mode.
*  - Statistics for specific ECC errors detected.
*  - Information about address where the last error was detected.
*
* The XMpmc device driver provides the following abilities for Performance
* Monitoring:
*  - Enable and Disable Performance Monitoring.
*  - Clear the Performance Monitoring Data Bins.
*  - Get and Clear the the Performance Monitoring Data Bins Clear Status.
*  - Get the Global Cycle Count, Dead Cycle Count and Peformance Monitoring Data
* 	for the Data Bins.
*
* The XMpmc device driver provides the following abilities for Static Phy:
*  - Read and Write to the Static PHY register.
*
*
*<b> Initialization and Configuration </b>
*
* The device driver enables higher layer software (for example, an application)
* to communicate with the MPMC device.
*
* XMpmc_CfgInitialize() API is used to initialize the XMpmc device instance.
* The user needs to first call the XMpmc_LookupConfig() API which returns the
* Configuration structure pointer which is passed as a parameter to the
* XMpmc_CfgInitialize() API.
*
*<b> Interrupts</b>
*
* The MPMC device has one physical interrupt which must be connected to
* the interrupt controller in the system. The driver does not provide any
* interrupt handler for handling the interrupt. The users of this driver
* must connect their own interrupt handler with the interrupt system.
*
* <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> 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> Hardware Parameters Needed</b>
*
* To use this driver with the MPMC device one of the following functionalities
* must be enabled:
* 		- ECC capability
*		- Performance Monitoring
*		- Static PHY
*
* The interrupt capability for the device must be enabled in the hardware
* if interrupts are to be used with the driver. The interrupt functions of
* the device driver will assert when called if interrupt support is not
* present in the hardware.
*
* The ability to force errors is a test mode and it must be enabled
* in the hardware if the control register is to be used to force ECC errors.
*

*
* Ver   Who  Date     Changes
* ----- ---- -------- -----------------------------------------------
* 1.00a mta  02/24/07 First release
* 2.00a mta  10/24/07 Added support for Performance Monitoring and Static PHY
