True I was confused:
static void
maininit(void)
{
// Initialize internal interfaces.
interface_init();
// Setup platform devices.
platform_hardware_setup();
...
}
I see this
interface_init -> qemu_cfg_init
platform_hardware_setup -> qemu_platform_setup -> pci_setup
So it's already called before pci_setup.
As you said no need to change things.
