The PCH is enforcing all these write / read protections. The SPI controller
lives in the PCH.

I tried looking for an answer to this but a quick one didn't surface:
when flash regions are protected, is this implemented by the flash chip
itself or by the SPI logic (ie ichspi for Intel programmer)?
It can be implemented by either, though in most cases it's the SPI
controller on Intel systems.
