Hi,
I would like to add support for mt7620n based Asus RT-N14U router. Device is curently running latest asus firmware which
is based on some older openwrt. I have telnet access to the shell and I was even able to build original firmware from source code.
For more information about hardware please see http://wikidevi.com/wiki/ASUS_RT-N14U.
There already seems to be support for ramips/mt7620n platform in trunk. So should I just add support for the board by providing
/target/linux/ramips/dts/RT-N14U.dts file? And if it so is there some more information about how to write those files?
Any help is welcome
