It fixes two main issues on Espressobin board that 'env default -a' completely erases permanent board MAC addresses and also erase $fdtfile variable which is needed for booting Linux kernel via distro boot. Lot of people were complaining about erasing permanent MAC addresses by U-boot on this board and due to this issue some linux distributions started using static hardcoded MAC addresses for all Espressobin boards to workaround this issue. Apparently erase of MAC addresses or usage of static hardcoded value caused more issues on network (e.g. inability to connect two of these boards to the same network).
