TS201 SDRAM connections for backward compatibility

For 64-bit memory is there a problem with connecting the DSP address bus as follows:

 

SDRAM     A0-A9          A10      A11     A12     BA0-BA1

DSP          A1-A10     SDA10     A12     A15     A13-A14

 

This would allow for installing devices with 12-bit address bus in place of the bigger devices with 13-bit address bus without creating holes in the address space.

 

Thanks,
