I recently ripped the ddrsdram controller out of EDK (opbddr_v2_00_b)
and got it working. There are a few bugs but they are things I can
live with as I intend to use it as a piece of stand-alone IP where I
have explicit control of the interface. This version supports bursts
of 8. If you are still interested in doing this, send me an email
describing the problems you have & I'll try to give you a few tips.
