+ibm,dynamic-memory-v2
+
+This property describes the dynamically reconfigurable memory. This is
+an alternate and newer way to describe dyanamically reconfigurable memory.
+It is a property encoded array that has an integer N (the number of
+LMB set entries) followed by N LMB set entries. There is an LMB set entry
+for each sequential group of LMBs that share common attributes.
+
+Each LMB set entry consists of the following elements:
+
+- Number of sequential LMBs in the entry represented by a 32bit integer.
+- Logical address of the first LMB in the set encoded as a 64bit integer.
+- DRC index of the first LMB in the set.
+- Associativity list index that is used as an index into
+  ibm,associativity-lookup-arrays property described earlier. This
+  is used to retrieve the right associativity list to be used for all
+  the LMBs in this set.
+- A 32bit flags word that applies to all the LMBs in the set.
