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,architecture.vec": Bidirectional communication mechanism between the host system and the front end processor indicating what features the host system supports and what features the front end processor will actually provide. In this case, we are indicating that the host system can support the new device tree structure "ibm,drc-info".
