There is a lot of follow-up traffic on how exactly to develop the needed
interfaces for reading mac address in mtd and/or network subsystem.

But, I don't think any of that negates the need for nvmem lookups that
work for non-device-tree and populating the lookups in mach-davinci
board code.

I am going to send patches 1-7 to ARM-SoC soon, so please do say if
there is any disagreement on this.
