[LinuxBIOS] Winbond W39V040BPZ support in flash_rom?

[Carl-Daniel U. Hailfinger]

Hi,

my Asrock K8NF4G-SATA2 has a Winbond W39V040BPZ 4 Mbit LPC flash chip, but flash_rom doesn't find the chip.
Data sheet for the flash chip is available at http://winbond-usa.com/products/winbond_products/pdfs/Memory/W39V040Bd.pdf


# flashrom -V
Calibrating delay loop... Setting up microsecond timing loop
510M loops per second

Any chance to get support for that flash chip on my board?
