Intel southbridges support "flash sharing" so that both the system
CPU and the NIC can use one and the same flash chip.

If there is indeed a blob in the factory BIOS that is required for
your NIC to operate, then you'll have to teach coreboot about this
flash sharing scheme. At the very least it will require putting the
NIC blob at a predefined location in flash, but I doubt it stops

Since your NIC is onboard and does not work I suppose this is what
you're up against.
