How to get the serial number of the VF-61 module on Linux?

From what I saw on WinCE it is possible to view the serial number of the module. Is there a way to do this in Linux too?

root@colibri-vf:~# cat /proc/device-tree/serial-number 
04875007

The /proc/device-tree/serial-number should provide the serial number of the module.

Thank you very much. Problem solved.
