Please check setting of EBIU_SDBCTL register.
Try following.
If your SDRAM size is 32MB, then use EBIU_SDBCTL = 0x0013

Sounds like address bits are not getting set. Stop at the boundary and
single step it if you can to watch the internal dma registers. Sorry I
don't know anything about this particular processor.
