Airoha based SoC declare a dedicated partition at the end of the flash to store calibration and device specific data, in addition to fixed partitions. The offset of this special partition is not well defined as it depends on flash bad block management that might require reserving additional space at the end of the flash. This binding allows defining all fixed partitions and marking the last one to detect the correct offset.
