Hi Sandy,
What is the result of `lspci -nn | grep ISA` on your system? I uploaded a
patch for Lewisburg PCI IDs here: https://review.coreboot.org/#/c/20922/

I have tested Lewisburg PCH + W25Q256xxx and it seems to work. Let me know
if you need any help applying the patch and testing it out on your system.
