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

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

The LPC device is not recognized.
Can you try to add your LPC device to the table in flash_enable.c:enables[]
You have to find out the correct device ID since there are several IDs for the LPC device you posted: 0260 MCP51 LPC Bridge 0261 MCP51 LPC Bridge 0262 MCP51 LPC Bridge 0263 MCP51 LPC Bridge
I'd start out using the enable_flash_ck804() function to enable flash access on that system because the flash enable mechanism is often similar across generations of LPC devices from one manufacturer.

There is one small problem: I depend on this board very much since my laptop is in repair. So I can't test whether writing would work. The only difference between W39V040B (new) and W39V040A (supported) ist that W39V040B is a LPC chip instead of FWH. I don't know whether that matters for flashing.

It shouldn't. FWH is also LPC, but with some added IO functionality.

Applied.
