U-Boot loads DTB file supplied by user/boot script and inserts MAC address into it. So if user boots this U-Boot on V7 board and supply kernel's V7 DTB file then U-Boot inserts WAN mac address into ethernet1 alias which is linked to switch0port3 (wan). So I think it is correct. We do not need any V7 DTS file in U-Boot. > > > > > > Recent Linux kernel versions use correct permanent ethernet MAC address from U-Boot env as > > > > U-Boot will inject it into kernel's device-tree. > > > > > > > >
