MT7621 status

[Yury]

As a newbie in this area I am wondering is there any how-to how can I build and 
install FreeBSD on Asus AC-RT65P with MT7621 SoC which is MIPS32 1004kec 
(double-core plus with hyper-threading, I see it as a rather decent hardware). I 
see the SoC has configuration files in 12-STABLE /usr/src mentioning it. So I 
believe it is possible to some extent to build and install FreeBSD on my device, 
isn't it?
