+# Usage:

+#
+# Get the partition address, based on the path or label.
+# The value will be returned in the <var> parameter.
+# The returned address is either relative to the memory controller, or absolute if ABSOLUTE is
+# specified.
+#
+# The <path> value may be any of these:
+#
+# - absolute path to a node, like '/foo/bar'
+# - a node alias, like 'my-alias'
+# - a node alias followed by a path to a child node, like 'my-alias/child-node'
+#
+# Results can be:
+# - The base address of the register block
+# - <var> will be undefined if node does not exists or does not have a register block at the
+#   requested index or with the requested name
+#
+# <var>          : Return variable where the address value will be stored
+# LABEL <label>  : Node label
+# PATH <path>    : Node path
+# TARGET <target>: Optional target to retrieve devicetree information from
