into account (bits padded to a width of 256, depending on the number of
elements per ddr word).
The DMA specific parameters give to this function (elems_per_xword and sign_extend)
should correspond to those given to the DMA engine.
The address is a virtual address which will be translated to a physical address before
data is loaded from or stored to that address.
The return value is 0 in case of success and 1 in case of failure.
