+The following constraints are relevant to the FBPR private memory:
+ - The size must be 2^(size + 1), with size = 11..33. That is 4 KiB to
+ 16 GiB
+ - The alignment must be a muliptle of the memory size
+
+The size of the FBPR must be chosen by observing the hardware features configured

+QMan Node
+
+The Queue Manager is part of the Data-Path Acceleration Architecture (DPAA). QMan
+supports queuing and QoS scheduling of frames to CPUs, network interfaces and
+DPAA logic modules, maintains packet ordering within flows. Besides providing
+flow-level queuing, is also responsible for congestion management functions such
+as RED/WRED, congestion notifications and tail discards. This binding covers the
+CCSR space programming model

+QMan Private Memory Nodes
+
+QMan requires two contiguous range of physical memory used for the backing store
+for QMan Frame Queue Descriptor (FQD) and Packed Frame Descriptor Record (PFDR).
+This memory is reserved/allocated as a nodes under the /reserved-memory node
+
+The QMan FQD memory node must be named "qman-fqd"
+
+PROPERTIES
+
+- compatible
+ Usage: required
+ Value type: <stringlist>
+ Definition: Must inclide "fsl,qman-fqd"
+
+The QMan PFDR memory node must be named "qman-pfdr"
+
+PROPERTIES
+
+- compatible
+ Usage: required
+ Value type: <stringlist>
+ Definition: Must inclide "fsl,qman-pfdr"
+
+The following constraints are relevant to the FQD and PFDR private memory:
+ - The size must be 2^(size + 1), with size = 11..29. That is 4 KiB to
+ 1 GiB
+ - The alignment must be a muliptle of the memory size
+
+The size of the FQD and PFDP must be chosen by observing the hardware features
+configured via the Reset Configuration Word (RCW) and that are relevant to a
+specific board (e.g. number of MAC(s) pinned-out, number of offline/host command
+FMan ports, etc.). The size configured in the DT must reflect the hardware
+capabilities and not the specific needs of an application
