Can NIOSII use burst data read from SDRAM

I know that the instruction cache can use burst read since there is a signal i_readdatavalid in the instruction bus. But there is no this signal in the data bus. Could we read data from SDRAM using burst mode from SDRAM?

Thanks!

    Unfortunately the Nios II/f data cache only has one word lines so can't burst to SDRAM.

    I believe this ability will become even more important with DDR.
