2015-06-03	spapr_drc: add spapr_drc_populate_dt()	Michael Roth
	This function handles generation of ibm,drc-* array device tree properties to describe DRC topology to guests. This will by used by the guest to direct RTAS calls to manage any dynamic resources we associate with a particular DR Connector as part of hotplug/unplug. Since general management of boot-time device trees are handled outside of sPAPRDRConnector, we insert these values blindly given an FDT and offset. A mask of sPAPRDRConnector types is given to instruct us on what types of connectors entries should be generated for, since descriptions for different connectors may live in different parts of the device tree. Based on code originally written by Nathan Fontenot.

2015-06-03	spapr_drc: initial implementation of sPAPRDRConnector device	Michael Roth
	This device emulates a firmware abstraction used by pSeries guests to manage hotplug/dynamic-reconfiguration of host-bridges, PCI devices, memory, and CPUs. It is conceptually similar to an SHPC device, complete with LED indicators to identify individual slots to physical physical users and indicate when it is safe to remove a device. In some cases it is also used to manage virtualized resources, such a memory, CPUs, and physical-host bridges, which in the case of pSeries guests are virtualized resources where the physical components are managed by the host. Guests communicate with these DR Connectors using RTAS calls, generally by addressing the unique DRC index associated with a particular connector for a particular resource. For introspection purposes we expose this state initially as QOM properties, and in subsequent patches will introduce the RTAS calls that make use of it. This constitutes to the 'guest' interface. On the QEMU side we provide an attach/detach interface to associate or cleanup a DeviceState with a particular sPAPRDRConnector in response to hotplug/unplug, respectively. This constitutes the 'physical' interface to the DR Connector.
