fw_printenv - Tool for printing the environment for the bootloader U-Boot

       fw_printenv  is  a  simple  tool for printing the environment for the bootloader U-Boot.  All environment
       variables matching the names given as  arguments  are  shown.   If  fw_printenv  is  called  without  any
       arguments the entire environment is printed.  This version of fw_printenv stems from libubootenv and does
       not hold a built-in default environment.  Instead, the default environment is read from a file.

       /etc/u-boot-initial-env
