* The xil_cache.h file contains cache related driver functions (or macros)
* that can be used to access the device.  The user should refer to the
* hardware device specification for more details of the device operation.
* The functions in this header file can be used across all Xilinx supported
* processors.
*
* <pre>
* MODIFICATION HISTORY:
*
* Ver   Who  Date     Changes
* ----- ---- -------- -------------------------------------------------------
* 1.00  hbm  07/28/09 Initial release
* 3.02a sdm  10/24/11 Updated the file to include xparameters.h so that
*                     the correct cache flush routines are used based on
*                     whether the write-back or write-through caches are
*                     used (cr #630532).
* 3.10a asa  05/04/13 This version of MicroBlaze BSP adds support for system
*					  cache/L2 cache. The existing/old APIs/macros in this
*					  file are renamed to imply that they deal with L1 cache.
*					  New macros/APIs are added to address similar features for
*					  L2 cache. Users can include this file in their application
*					  to use the various cache related APIs. These changes are
*					  done for implementing PR #697214.
