Great to hear. Please post a patch to [email protected] with a
Signed-off-by line, see

The datasheet for the chip is here:
http://www.winbond.com/hq/enu/ProductAndSales/ProductLines/FlashMemory/ParallelFlash/ParallelFlash/W39V040C.htm
If you're lucky it's similar enough to one of the other ones and you
only need to add the proper chip ID. If you meant the 'W39V040C'
(note the added '0') then please try the attached patch. Note that
I didn't carefully check the datasheet, I just blindly added the IDs,
so there's no guarantee it'll actually work ;-)
The ID is mentioned on page 11 ('Product Identification Registers').

Yes, flashrom development happens on the coreboot (previously known
as LinuxBIOS) mailing list (CC'd), see http://www.coreboot.org/Mailinglist.
I recommend to subscribe to that list.
Cheers, Uwe.
