Hi Neil, thanks for your work on this!

Unfortunately on boards with these older SoCs the serial number and MAC address are often not stored in the eFuse. This is just an example, so I won't be sad if we keep them. To avoid confusion I suggest switching to different examples: ethernet_mac_address: mac@1b4 { reg = <0x1b4 0x6>; }; temperature_calib: calib@1f4 { reg = <0x1f4 0x4>; }; What do you think? Best regards, Martin
