[Qemu-devel] [PATCH 02/15] sun4u: ebus QOMify tidy-up |
Date: |
Fri, 17 Nov 2017 13:42:34 +0000 |
The main change here is to introduce the proper TYPE_EBUS/EBUS QOM macros
and remove the use of DO_UPCAST.
Alongside this there are some a couple of minor cosmetic changes and a rename
of pci_ebus_realize() to ebus_realize() since the ebus device is always what
is effectively a PCI-ISA bridge.
