Interface 4 GB of flash rom to C6672

How do I interface 4 GB of flash rom to the c6672 chip? Any known, tried implementation?

If I use 2 C6672 chips (one support 256 MB NAND flash), does it mean that 2 will support 512 MB?

    The data manual mentions that EMIF16 supports 16MB of NOR and 256 MB of NAND. However, there are other methods (I2C and SPI) to connect NOR and NAND rom to c6672.

    If so, can I then connect 4 GB of NAND or NOR ROM to the I2C and SPI interface? What is the limit (maximum rom capacity supported) for I2C and SPI?
