[Qemu-devel] [PATCH v2 03/11] versatile_pci: Update to realize and instance init functions |
Date: |
Tue, 26 Mar 2013 10:22:03 +0000 |
Update the Versatile PCI controller to use a realize function rather
than SysBusDevice::init. To reflect the fact that the 'realview_pci'
class is taking most of its implementation from 'versatile_pci' (and
to make the QOM casts work) we make 'realview_pci' a subclass of
'versatile_pci'.
