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