Hi,
On my m57sli-rev.2 board, there is a winbond 25X40 SPI flash bios chip, which flashrom didn't have support for, so I added it (and the relatives). Patch below:

Sorry, that's not really a Winbond flash chip, it is a Nexcom/Nexflash flash chip. Nexcom was acquired by Winbond, but the vendor ID for your chips is still 0xEF (Nexcom).
I'll post an updated patch tomorrow.
Regards, Carl-Daniel
