+properties define the address and size of an initrd blob. Note that
+initrd-end is the first address after the initrd image, so this doesn't
+match the usual semantic of struct resource. The chosen node may also
+optionally contain an arbitrary number of additional properties for
+platform-specific configuration data.
During early boot, the architecture setup code calls of_scan_flat_dt()
several times with different helper callbacks to parse device tree
