The WKUP system controller address region contains an eFuse block with MAC addresses to be used by the Ethernet controller. The property “ti,syscon-efuse” contains a phandle to a syscon region and an offset into this region where the MAC addresses can be found. Currently "ti,syscon-efuse" points to the entire system controller address space node with an offset to the eFuse IP address. Instead add a cpsw-mac-efuse node to describe the exact eFuse area. Then point the Ethernet controller directly to this region, no offset needed.
