Cache coherent type definitions
#define	OSAL_CACHEP_COHERENT   ((uint32_t) 0U)
#define	OSAL_CACHEP_NOT_COHERENT   ((uint32_t) 1U)
typedef uint32_t	Osal_CacheP_isCoherent
	This enumerator defines the cache coherent types. More...

Set Cache MAR register
#define	CacheP_Mar_DISABLE   (0U)
#define	CacheP_Mar_ENABLE   (1U)
typedef uint32_t	CacheP_Mar
	This enumerator defines the MAR register setting types. More...

Functions
void	CacheP_wb (const void *addr, uint32_t size)
	Function to write back cache lines. More...
void	CacheP_Inv (const void *addr, uint32_t size)
	Function to invalidate cache lines. More...
void	CacheP_wbInv (const void *addr, uint32_t size)
	Function to write back and invalidate cache lines. More...
void	CacheP_fenceCpu2Dma (uintptr_t addr, uint32_t size, Osal_CacheP_isCoherent isCoherent)
