So you really need to upstream the fpga dts - if this just for initial
bringup and you will eventually switch to silicon.
The reason I say is every additional file is a maintenance burden so
better to avoid things which are only temporary.
But if you plan to support this config in long run I'm fine !
Looking further it seems first one is a "common" include style dts while
fpga is for actual platform and the SoC one will follow once you get it
running ?
That is correct. the '_fpga.dts' is the tree for the current emulation
board. The plan is to use the fpga platform until the actual silicon
arrives and is brought up. I included the _fpga dts in order to have a
way to verify that the anarion DTSI compiles. I also plan to later
remove the fpga dts once the actual silicon works.

Perhaps put a one liner that this is based on SNPS ARC700 cpu !
Staged for [PATCH v2].
