Hi!
Thanks for the logs. It seems like your board uses a superio chip that is not supported by flashrom yet. carl-daniel is working on a patch for it, but it does (or should) only detect that chip at the moment - it does not enable read or write access. please do not expect flashrom to work on that board soon, sorry.
the current patch: http://patchwork.coreboot.org/patch/3713/
