The constants MTDPART_OFS_* are purposely not included. Indeed, parse_ofpart_partitions() is expecting u64, but a DT cell is u32. Negative constants, as defined by MTDPART_OFS_*, would be wrongly interpreted by parse_ofpart_partitions(). Two cells should be used to correctly encode the negative constants, but this breaks current usage.
