+         Since SPL normally runs in a reduced memory space, the device tree
+         is cut down to only what is needed to load and start U-Boot. Only
+         nodes marked with the property "u-boot,dm-pre-reloc" will be
+         included. In addition, some properties are not used by U-Boot and
+         can be discarded. This option defines the list of properties to
+         discard.
