Fusing MAC addresses in IMX8

Hello everyone,

 

I want to fuse the correct fuses using UBoot. However, I'm slightly confused about the fusing of MAC addresses for IMX8. According to reference manual, on Page 876.

Fuse address (offset ) for MAC is 0x640. I interpreted the following: This fuse is 32 bits long,  reseved for higher 16 bits. How would i program the Lower 32 bits?

 

 

This is stated on Page 885. Offsets at 0x640, 0x650, 0x660 are reserved for writing MAC addresses from software.

 

 

I'm really confused as to how to interpret this ambiguous information regarding MAC_ADDR fuses.
