device tree

[Stefan Reinauer]

Hi,

what's the right way of getting the pci ids of a device when
traversing the device tree?

is seems that the "path" part can be used, but there's no reference to
the real hardware. I need this only _after_ pci initialization.

The config tool creates the following structure for an 8131 for example:

struct chip amd8131 = {
        .link = 1,
        .path = { 
                { .enable = 1, .path = {.type=DEVICE_PATH_PCI,.u={.pci={ .bus = 0x0, .devfn = PCI_DEVFN(0x0,0) }}}},
                { .enable = 1, .path = {.type=DEVICE_PATH_PCI,.u={.pci={ .bus = 0x0, .devfn = PCI_DEVFN(0x0,1) }}}},
                { .enable = 1, .path = {.type=DEVICE_PATH_PCI,.u={.pci={ .bus = 0x0, .devfn = PCI_DEVFN(0x1,0) }}}},
                { .enable = 1, .path = {.type=DEVICE_PATH_PCI,.u={.pci={ .bus = 0x0, .devfn = PCI_DEVFN(0x1,1) }}}},
        },
        .next = &amd8111,
        .children = 0,
        .control= 0,
        .chip_info= 0,
};
