Add Mainboard Suport

[Jean Marques]

Hi.
I've built and ran the most recent version of flashrom, I can read the
eeprom but I can't write or erase chips. It's possible to add suport?
I have spare eeproms and a backup of my bios. I'm trying to do hotswap
flashing. The motherboard is 775Twins-HDTV. I have a log atached.

Thank you.
