everything looks good except I'd try changing the above to something like:

DPDPTR->fld[i].ptr = dma_map_single(NULL, ...ptrOffset1st,
		...lenOffset1st, DMA_TO_DEVICE);

and change the DMA_BIDIRECTIONAL to DMA_TO_DEVICE in the DPD's address assignment.

btw, a BSP upgrade (based on 2.6.11) for your platform should be available in a couple of weeks.  I'll let you know the status of the SEC driver for it.
