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.
