Ahem. Well. I'd love to. It even used to be that way, before QOM.
uhci had a simple PCIDeviceInfo table, with an entry for each variant.
QOM turned that a bunch of class_init functions ...
Looking a bit closer (at include/qemu/object.h): seems we can pass
additional data to TypeInfo->class_init via TypeInfo->class_data. That
should help here.
I'll go try that to simplify uhci ...
cheers,
Gerd
