Nice thing is that on this (not yet implemented) chipset we don't seem
to need a chipset specific flash enable function, just a board-specific
flash enable function for your board. This function interacts with the
Winbond Super I/O chip (it clears bit 2 of reg E4 and sets bit 3 of reg
F1 in LDN 9, for the tech-savvy people here), and thus we very much
appreciate the output of superiotool -deV on your board.

We prefer you to use a recent superiotool version obtained from the
subversion repository using

> $ svn co svn://coreboot.org/coreboot/trunk/util/superiotool
> $ cd superiotool
> $ make
> $ sudo make install

This will give us enough information to make sense of the bits mentioned
above and add support for that mainboard in flashrom.
