Add new device Support in OpenWrt

This is also to add support for the OpenWrt to the small-level route
Write a new device to the Target/linux/ramips/image/makefile

image/build/profile/mt7620a_clz=$ (Call buildfirmware/default8m/$ (1), $ (1), MT7620A_CLZ, MT7620A_CLZ) $ (call image/build/profile/mt7620a_clz,$ (1))

Some of the available configurations in Base-files:

BASE-FILES/ETC/DIAG.SH controls whether the LEDs blink when the OpenWrt is started
Base-files/lib/upgrade/platform.sh allows Sysupgrade to work
Base-files/etc/uci-defaults/network to configure (install) default network interface (interface) settings, particularly MAC addresses
Base-files/etc/uci-defaults/leds If you have configurable (configurable) LEDs which should default to a behavior (behavior), like a WLAN a Ctivity LED
Base-files/etc/hotplug.d/firmware (firmware)/10-rt2x00-eeprom to extract (extract) the firmware image for the wireless (wireless) module
Base-files/lib/preinit/06_set_iface_mac to set the MAC addresses of any other interfaces (interface)

DTS files for small-size routes written

After adding a device, it is best to delete the temporary files generated by the previous compilation, as follows

-RF tmp make Menuconfig
