enum SaSi_PalDmaBufferDirection_t

Enumerator
SASI_PAL_DMA_DIR_NONE	No direction.
SASI_PAL_DMA_DIR_TO_DEVICE	The original buffer is the input to the operation, and should be copied/mapped to a temp buffer, prior to activating the HW on the temp buffer.
SASI_PAL_DMA_DIR_FROM_DEVICE	The temp buffer holds the output of the HW, and this API should copy/map it to the original output buffer.
SASI_PAL_DMA_DIR_BI_DIRECTION	Used when the result is written over the original data at the same address. should be treated as 1 & 2.
