How does a chipset know the size of the SPI BIOS ROM on board

Chipsets do not know the size of the flash ROM chip.

Ok. Thanks for the explanation, Carl-Daniel and Rudolf.

I tried substituting a bigger SPI ROM chip on my test mainboard and it worked very well. Flashrom and Coreboot co-operate very nicely. The only change needed was configuring Coreboot to use a bigger ROM size in menuconfig.

The original chip was MX25L8005 (1 MByte) and the substitute is MX25L1605 (2MByte). The ROM is connected to AMD SB700 southbridge.

Best regards,
