What exactly are you talking about ? It is amdk8_scan_root_bus
in ibm/e325/mainboard.c.
static struct device_operations mainboard_operations = {
.read_resources = root_dev_read_resources,
.set_resources = root_dev_set_resources,
.enable_resources = enable_childrens_resources,
.init = mainboard_init,
.scan_bus = amdk8_scan_root_bus,
.enable = 0,
};
