I bet there is a to of existing ways to encode and pass such
information - in NOR flash, EEPROM, encoded in the serial number
and/or MAC addresses, whatever.  I would expect that each major board
vendor has his preferred style, and I don't see how this could be
changed.

Also, pleas ekeep inmind that there are two sides of the issue:

- storage device and format for the related information

- method and for mat of passing this on to the kernel

The Subject: addresses only the second part of this.  And as mentioned
before, there is a standardized method of passing such infoirmation to
the kernel - through the device tree.

Best regards,

Wolfgang Denk
