Hi guys, I'm trying to port an old Intel version of coreboot for tunnelcreek to a newer version of the coreboot code.
I'm stuck at a point in which the boot stops at get_pbus(device_t dev) because dev is NULL (0x0).
I think the problem is in a function that calls pci_write_config32, but using PCI_DEV(0,0,0) to access the bus 0, device 0, function 0. PCI_DEV(0,0,0) evaluates to 0x0, which get_pbus interprets as a NULL pointer. This is used in the 'dev' parameter of pci_write_config32.
I looked at the source code and in the mailing list, but couldn't find a way to pass a correct dev parameter to the function. I'm also not so sure I am in the right path. I may be confusing thing a little, since I'm no so experienced in x86 hardware and firmware levels. I'm also learning coreboot at my own, it's a lot of information at the same time being pushed at my brain! ;)
I appreciate any help and clarifications!
Thank you very much!
