I am playing with Arduino Yùn at the moment.
I have been wondering what is the purpose of target/linux/ar71xx/legacy-devices.mk and target/linux/ar71xx/generic.mk ?
Wouldn't it be good to import this patch then : https://github.com/nxhack/openwrt-yun-build-extra/blob/master/patches/LEDE-YUN-Legacy2Generic.patch ?
Documentation about that would be welcome as there is no comments in the source tree. I have quite a hard time to understand how things work.
