MCF5329/Flash support

Hi,
     Our application requires 256Mb (16Mbx16) of Flash memory for storage. Based on this, we have selected a flash chip from Numonyx of the same requirement. However, the chip has address lines from A25 to A1 whereas the processor address lines are from A23 to A0. At this point, I am seeing only 2 solutions for this interface - either to use any GPIO lines to drive the remaining address bits or go for multiple-chip solutions instead of the single-chip one. Can anyone help me out? I would prefer a single-chip solution rather than a multiple-chip one.

Thanks and regards,
