I agree with you. I'm going to fork buildroot repository from github and 
will keep it updated + adding Amlogic things step by step.

Amlogic is Chinese SoC manufacturer. There are 3 different SoCs used in 
Buildroot for Amlogic devices. It's M1 (800 MHz single-core cpu), M3 
(1GHz single core cpu) and MX/M6 (Dual-Core 1.5GHz CPU).

Amlogic SoC exists in tablets, STBs (Android TV box) and smart TV-s. All 
forks you mentioned here are STB based, intended to run Linux XBMC on top 
of it.

My fork covers MX/M6 platform, while Pivosgroup you mentioned covers M1/
M3 platform.

It's not that easy to put it all together, but will do my best to add 
Amlogic support to mainline buildroot.

I started doing this way I did till now because it was simple to fork eg. 
vDost's buildroot which was already prepared at the moment for Amlogic 
MX :)

Anyway, I'll to keep on track, but with all the work I have, I can't tell 
how fast/slow it will go.
