NOR FLASH interface to Xeon D 1559

Is there a provision to interface Larger (256 MB)NOR FLASH to XeonD 1548/1559?We do not want to use NAND FLASH supported on SATA. We want to explore these possibilities. 

1. Can a larger NOR FLASH (256MB) be connected to SPI0 and SPI1 and increase address space?

2. Can LPC bus be used for a NOR FLASH interface? Is there any reference design available?

Looks like we can expand LPC bus up to 256MB per device with additional glue logic in FPGA. Is it possible to modify SPI FLASH range to 256MB? If possible, how to achieve this?
