The patches referenced above include purely device-tree based Syborg and Stellaris boards. It works fairly nicely for some embedded boards, but gets fairly hairy when you start considering more complex topologies/machines. I particular the PCI OF/FDT bindings don't really fit what we need for qemu. Obviously full qdev conversion is a prerequisite for device tree based configuration, and at that time qdev was still in its infancy. Part of the reason for posting that patch was to demonstrate the abstraction layers required for the internal device model. Previous patches tended to be based on the pre-existing PC commandline options, which IMO is a mistake. Likewise if (like my implementation) you focus on embedded machines you risk serious problems trying to extend to server class machines. Paul
