+description: |
+  Sercomm is one of hardware manufacturers providing SoCs used in home routers.
+  The Sercomm partition map table contains information about non-standard
+  partition offsets and sizes (depending on the bad blocks presence and their
+  locations). Partition map is used by many Sercomm-based Ralink devices
+  (e.g. Beeline, Netgear).
