3 Reserved memory is specified as a node under the /reserved-memory node.
4 The operating system shall exclude reserved memory from normal usage
6 normal use) memory regions. Such memory regions are usually designed for
9 Parameters for each memory region can be encoded into the device tree
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.

50         - shared-dma-pool: This indicates a region of memory meant to be
57       of the region as part of its standard mapping of system memory,
61     - The operating system can use the memory in this region with the
72   region for the default pool of the contiguous memory allocator.
77 Device node references to reserved memory
79 Regions in the /reserved-memory node may be referenced by other device
80 nodes by adding a memory-region property to the device node.
82 memory-region (optional) - phandle, specifier pairs to children of /reserved-memory
83 memory-region-names (optional) - a list of names, one for each corresponding
84   entry in the memory-region property
