OK, I am now almost at the limit of my understanding :-)
I need to set up the device_operations for the 8601. Here is the mainboard config that is relevant.
northbridge via/vt8601 "vt8601" pci 0:0.0 pci 0:1.0 southbridge via/vt8231 "vt8231" pci 0:11.0 pci 0:11.1 pci 0:11.2 pci 0:11.3 pci 0:11.4 pci 0:11.5 pci 0:11.6 pci 0:12.0 register "enable_usb" = "0" register "enable_native_ide" = "1" register "enable_com_ports" = "1" register "enable_keyboard" = "0" register "enable_nvram" = "1" end end
Now there is nothing special about the 8601 enumeration wise.
So I was hoping to do this:
static void enumerate(struct chip *chip) { extern struct device_operations default_pci_ops_bus; chip_enumerate(chip); chip->dev->ops = &default_pci_ops_bus; }
struct chip_control northbridge_via_vt8601_control = { .enumerate = enumerate, .name = "VIA vt8601 Northbridge", };
and
static void enumerate(struct chip *chip) { extern struct device_operations default_pci_ops_bus; chip_enumerate(chip); chip->dev->ops = &default_pci_ops_bus; }
struct chip_control southbridge_via_vt8231_control = { .enumerate = enumerate, enable: southbridge_init, name: "VIA vt8231" };
Which, basically, doesn't work :-(

===========================================================================
you can see they go to pieces at the end.
I'd like to have it such that if there is no enumerate struct member, the "right things" happen.
Any advice on the best way to do this? I'm still working out the static/dynamic stuff on V2, and clearly have got it wrong.
Anyway I'm still digging ...
