Hello, Coreboot community!
I work ASUS P8B75-V port with Nuvoton 6779d Super I/O. I have a problem: after the first call of post_code(...) function I get post-code x80 on PCI Port80 regardless which post-code I send. In debug console I see that all postcodes are correct, but only x80 is at all three PCI buses. I think that the problem may occur because the register, which saves last postcode value, isn't connected (or connected incorrectly) with PCI/Port80, but I am not sure.
Could you help me with my problem, please?
