"ibm,drc-info": This property, when present, replaces the following four properties: "ibm,drc-indexes", "ibm,drc-names", "ibm,drc-types" and "ibm,drc-power-domains". This property is defined for all dynamically reconfigurable platform nodes. The "ibm,drc-info" elements are intended to provide a more compact representation, and reduce some search overhead. "ibm,dynamic-memory-v2": This property replaces the "ibm,dynamic-memory" node representation within the "ibm,dynamic-reconfiguration-memory" property provided by the BMC. This element format is intended to provide a more compact representation of memory, especially, for systems with massive amounts of RAM. To simplify portability, this property is converted to the "ibm,dynamic-memory" property during system boot. "ibm,architecture.vec": Bit flags are added to this data structure by the front end processor to inform the kernel as to whether to expect the changes to one or both of the device tree structures "ibm,drc-info" and "ibm,dynamic-memory-v2". Signed-off-by: Michael Bringmann Michael Bringmann (8): powerpc/firmware: Add definitions for new firmware features. powerpc/memory: Parse new memory property to register blocks. powerpc/memory: Parse new memory property to initialize structures. pseries/hotplug init: Convert new DRC memory property for hotplug runtime pseries/drc-info: Search new DRC properties for CPU indexes hotplug/drc-info: Add code to search new devtree properties powerpc: Check arch.vec earlier during boot for memory features powerpc: Enable support for new DRC devtree properties
