Subject: macio: Fix macio-bus to be a subtype of System bus
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6741a3430b59cfbdb97a2194dcc16a4fedce486d;p=qemu.git

macio: Fix macio-bus to be a subtype of System bus

The devices we plug into the macio-bus are all sysbus devices
(DeviceClass member bus_type is TYPE_SYSTEM_BUS), but macio-bus does
not derive from TYPE_SYSTEM_BUS.  Fix that.

"info qtree" now shows the devices' mmio ranges, as it should
