Booting P1022 from SPI Boot ROM

Hi, We would like to boot P1022 using SPI EEPROM N25Q256A13ESF40F. We have set cfg_rom_loc[0:3]=0110. The chip defines the default boot ROM address range to be 8 Mbytes at address 0x0_FF80_0000 to 0x0_FFFF_FFFF.

In case of booting from parallel NOR flash (local bus GPCM mode) we set the option register (OR) and base register (BR) corresponding to chip select 0 (CS0) properly so as to specify the desired address range.

Please suggest how to configure the similar settings for booting from SPI.
