Physical address - MAC ID non-volatlie storage

Is there any special non-volatile storage such as a small OTP section of flash on ColdFire Microcontrollers where the FEC's physical address MAC ID can be stored?

 

In other words, how are most real-world applications (with ColdFire MCUs and MPUs) dealing with storing and using a unique physical address (MAC ID) field in their product?    I'm thinking that if there isn't a small OTP section of flash in the ColdFire then most folks would be saving a unique MAC ID in external EEPROM and reading it in at startup and saving to the PALR and PAUR registers in the FEC.

 

Thanks in advance for your help.
