Hello Johannes,

thanks for your report!
I have marked the flash chip as fully tested and will commit that later
together with other small changes.

I have added that as well. The EC uses its own flash chip and should
not bother us. Since the board can run coreboot the EC does not
interact with the x86 firmware either so it is fine to white list it.
