Defining flash partition table in platform code is deprecated, and due to recent changes linkstation and storcenter do not compile any more with their default configurations because of undefined references to physmap_set_partitions(). Instead of fixing them by using the correct kernel configuration macro in preprocessor conditional, remove partition table definitions altogether. Instead add support for partition definition on the command-line and in device tree to the default configurations.
