Modified: trunk/board_enable.c Log: The GIGABYTE GA-7ZM has a maximum decode size (parallel chips) of 512 KB.
Add this information to the new field in the board-enable table. We match the board via two sets of PCI IDs. However, as we don't need a board-enable function for this board (it works out of the box; well, at least if you remove the JP9 jumper on the board), change the code to allow NULL as value for the board-enable function. There will likely be more boards in the future where we want to record a maximum decode size but which don't need a board-enable.
This is hardware-tested on the GIGABYTE GA-7ZM by successfully writing a 512KB image of random bytes to a chip in this board.

reveals that there are at least two different boards which matches this.
You are only matching the southbridge here, and a relatively bogus (and common) subsystem id, which only tells us that it's a gigabyte board.
The VT82C686 was a _hugely_ successful southbridge. I cannot even begin to count how many gigabyte boards use this chipset.
So, first; swap the pairs around. Second, use 0x1106, 0x0305, 0, 0 to at least narrow the northbridge down.
A further check on the gigabyte gives me 17 possible combinations of the different kt133 variations and the 686 southbridge. This makes it completely impossible to even consider the above change a sufficient match.
Please provide the output of flashrom -V so we can identify a DMI match.
The above logic should give you some idea of the investigation required to get a good match. It just takes a few minutes to do so too.
