DRA821U: MAC_ID on CPSW5G?

Other Parts Discussed in Thread: DRA821

Was asked by one of my customers about the existence of pre-programmed MAC_ID on the DRA821.  I originally pointed out Section 5.1.2.3.1.6 of the TRM which details the MCU_CPS0 MAC Address registers.  However, the customer noted that this was for the CPSW2G and they are interested in the CPSW5G.  Are there such registers?  I could not find a corresponding section in the TRM.

    John, 

    There are no registers for additional MACIDs. For CPSW5G, MACID can be assigned during u-boot, from customer's allocated MACID pool. At some point, we intended to assign the subsequent MACIDs from the MMR, for each device, but I don't think we proceeded with that due to wasting of MAC if they are not used.
