(2) The QEMU command line and the effects the command line has on the virtual hardware should not change. However, all of the following have to be updated:
- the "explicit_ofw_unit_address" property assignments in pxb_dev_initfn() have to be done separately, after all PXBs have been seen, and sorted. This probably requires another "machine init done" notifier.
I admit the sorting of pxb objects just to reverse engineer what SeaBIOS expects would not be fun. Doesn't QEMU have to sort the buses anyway to know which secondary bus ranges are associated with each root bus?
I guess it can be done - though this means it will break if we ever support hot-plugging of these roots. But more importantly, if the sort is by the bus number, then how is it better than just using the bus number directly?
