+With `REFERENCE_TYPE` it's possible to only generate the specified type of reference release. If set to `CLI`, only CLI firmware for hardware type specified by `REFERENCE_PLATFORM` is generated. If set to `OTBR`, only OTBR reference release which contains Raspberry Pi image and a RCP firmware will be generated. If this variable is not specified, all types of reference releases are generated.
