I can't find an MT7981 / Filogic 820 datasheet anywhere, but apparently 
MediaTek was nice enough to put out a public release for the MT7986 / 
Filogic 820 for the Banana Pi R3. Anybody know what the differences are? 
Could it just be quad vs dual core?

I'm also wondering if MediaTek could be convinced to make a public 
release of the MT7981B for this project.

To work on any MediaTek SoCs, if feels like you have to be an expert in 
all of them to know what microcode they're reusing for each component 
(peripheral interfaces, etc.) from one chip to the next, and thus the 
registers and behavior that had been previously published in a some 
other programmer's manual. It's a strange world to me.
