I mean for the SPI-NOR controller PCI device registers (not the LPC PCI
device, sorry about not being clear), like config space. Typically it is
PCI device 1f.5 and in that case you can't use the LPC driver because it
should not touch other devices than what it is bound to (OK, there are
exceptions but still).

If that's the case then I guess this should go to intel-spi-pci/platform
drivers after all. I think one option is that we add Kconfig option that
makes the driver load but only provide the security bits without
actually calling intel_spi_probe().
