The env scripts for loading and applying overlays are identical for many PHYTEC Boards. Create a common env that can be included.
The env variables bootenv_addr and fdto_addr are board specific and need to be set in the board specific file. The env variable get_cmd also needs to be set in board specific files and can be set to tftp or dhcp.
