[Qemu-devel] [PULL 41/47] ppc/pnv: populate device tree for IPMI BT devices |

From: Cédric Le Goater <address@hidden>
When an ipmi-bt device [1] is defined on the ISA bus, we need to
populate the device tree with the object properties. Such devices are
created with the command line options :
-device ipmi-bmc-sim,id=bmc0 -device isa-ipmi-bt,bmc=bmc0,irq=10
