You should IMHO split this up in two patches.
First patch: add terasic

Second patch: this.

The naming of this board still confuses me though.
It has 3 different names now:

	- de0_sockit.dts
	- Terasic DE-0(Atlas)
	- de0-nano-soc

And according to Terasic DE0-Nano-SoC is the same as Atlas-SoC with a different software?!
So all three names are actually correct ?! Weird.

Steffen
