12 /reserved-memory node
19 /reserved-memory/ child nodes
21 Each child of the reserved-memory node specifies one or more regions of
22 reserved memory. Each child node may either use a 'reg' property to
23 specify a specific range of reserved memory, or a 'size' property with
24 optional constraints to request a dynamically allocated block of memory.

71 Device node references to reserved memory
73 Regions in the /reserved-memory node may be referenced by other device
