[flashrom] Intel Atom E3845

Hello,

I'm working on Opencellular (https://code.fb.com/connectivity/introducing-opencellular-an-open-source-wir...) which is based on Intel Atom E3845. I have built the coreboot image and would like to flash onto the Opencellular board. Could you tell how to flash only onto the BIOS region using Flashrom?

Thank you, in advance.
