Public bug reported: powerpc/devtree: Add support for 2 new DRC properties to the Ubuntu distribution for powerpc
Several properties in the DRC device tree format are replaced by more compact representations to allow, for example, for the encoding of vast amounts of memory, and or reduced duplication of information in related data structures. "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".
