65 BMan Private Memory Node
67 BMan requires a contiguous range of physical memory used for the backing store
68 for BMan Free Buffer Proxy Records (FBPR). This memory is reserved/allocated as
69 a node under the /reserved-memory node.
71 The BMan FBPR memory node must be named "bman-fbpr"
75 - compatible
78 	Definition:	PPC platforms: Must include "fsl,bman-fbpr"
79 			ARM platforms: Must include "shared-dma-pool"
80 				       as well as the "no-map" property
82 The following constraints are relevant to the FBPR private memory:
83 	- The size must be 2^(size + 1), with size = 11..33. That is 4 KiB to
85 	- The alignment must be a muliptle of the memory size
89 (e.g. number of MAC(s) pinned-out, number of offline/host command FMan ports,
93 For additional details about reserved memory regions see reserved-memory.txt
97 The example below shows a BMan FBPR dynamic allocation memory node
99 	reserved-memory {
100 		#address-cells = <2>;
101 		#size-cells = <2>;
104 		bman_fbpr: bman-fbpr {
105 			compatible = "shared-mem-pool";
108 			no-map;
112 The example below shows a (P4080) BMan CCSR-space node
114 	bportals: bman-portals@ff4000000 {
129 		fsl,bman-portals = <&bportals>;
130 		memory-region = <&bman_fbpr>;
