+description: |
+  Airoha new SoC AN7581 expose banks of eFuse accessible
+  via specific SMC commands.
+
+  2 different bank of eFuse or 64 cells of 32 bit are exposed
+  read-only used to give information on HW Revision, PHY Calibration,
+  Device Model, Private Key...

+	  SoCs. These are e.g. used to store factory programmed
