*
* Driver for the retrieval of an IEEE address from flash
*
* The user can specify a hardcoded IEEE address through the
* IEEE_ADDR_CONF_HARDCODED configuration macro.
*
* If the user does not hard-code an address, then one will be read from either
* the primary location (InfoPage) or from the secondary location (on flash).
*
* In order to allow the user to easily program nodes with addresses, the
* secondary location is given priority: If it contains a valid address then
* it will be chosen in favour of the one on InfoPage.
*
* In this context, an address is valid if at least one of the 8 bytes does not
* equal 0xFF. If all 8 bytes are 0xFF, then the primary location will be used.
*
* In all cases, the address is assumed to be written little-endian.
*
* Lastly, it is possible to override the 2 LSB's of the address by using the
* NODE_ID make variable.
