Detailed Description

Function Documentation

uint32_t SaSi_PalMemMap	(	uint32_t	physicalAddress,
		uint32_t	mapSize,
		uint32_t **	ppVirtBuffAddr
	)

This function purpose is to return the base virtual address that maps the base physical address.

Returns

Zero on success.

A non-zero value in case of failure.

Parameters

[in]	physicalAddress	Start physical address of the I/O range to be mapped.
[in]	mapSize	Number of bytes that were mapped.
[out]	ppVirtBuffAddr	Pointer to the base virtual address to which the physical pages were mapped.

uint32_t SaSi_PalMemUnMap	(	uint32_t *	pVirtBuffAddr,
		uint32_t	mapSize
	)

This function purpose is to Unmap a specified address range previously mapped by SaSi_PalMemMap.

Returns

Zero on success.

A non-zero value in case of failure.

Parameters

[in]	pVirtBuffAddr	Pointer to the base virtual address to which the physical pages were mapped.
[in]	mapSize	Number of bytes that were mapped.
