"ibm,dynamic-memory-v2": This property replaces the "ibm,dynamic-memory" node representation within the "ibm,dynamic-reconfiguration-memory" node 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": 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,dynamic-memory-v2".
