// Purpose:      Cache control API
// Description:  The macros defined here provide the HAL APIs for handling
//               cache control operations.
//
//               For the Atcel SmartFusion, these are empty macros as there
//               is no cache.
// Usage:
//               #include <cyg/hal/hal_cache.h>
//               ...
//
