N1盒子的fw_printenv配置/etc/fw_env.config

from https://isolated.site/2018/12/23/get-fw_printenv-working-on-phicomm-n1/

fw_printenv / fw_setenv on Armbian does not work out of box:

# fw_printenv
Cannot parse config file '/etc/fw_env.config': No such file or directory

To solve this issue, put the following to /etc/fw_env.config:

# Device to access      offset               env size
/dev/mmcblk1            0x27400000      0x10000
