pci_bus_new*() and pci_register_bus() work only when the 'parent'
argument is a PCI_HOST_BRIDGE object. Rename them to reflect that they
are meant to initialize a bus that's in a PCI host bridge.
The new function names are:
* pci_host_bus_init() (replacing pci_bus_new())
* pci_host_bus_init_inplace() (replacing pci_bus_new_inplace())
* pci_host_bus_init_irqs() (replacing pci_register_bus())
I like the idea, but I'm not terribly convinced by these names.
Aren't functions which allocate objects usually called whatever_new()
rather than whatever_init()? And pci_register_bus() appears to do
more than just initialize irqs.
I agree the names aren't terribly clear. This is what they are
supposed to mean:
* pci_host_bus_init(phb) initializes phb->bus.
* pci_host_bus_init(phb) initializes phb->bus using an
already-allocated object.
* pci_host_bus_init_irqs() does the same as pci_host_bus_init(),
but also calls pci_bus_irqs().
I plan to submit API documentation comments later. I am open to
alternative name suggestions.
