Not all flash regions are freely accessible by flashrom. This is most likely due to an active ME. Please see https://flashrom.org/ME for details. At least some flash regions are read protected. You have to use a flash layout and include only accessible regions. For write operations, you'll additionally need the --noverify-all switch.
