A Board Configuration Example for The Freedom E310 Arty FPGA Dev Kit

[hirooih]

This configuration demonstrates how to run the Embench on an FPGA board.

The current Embench distribution does not include any examples of a FPGA board configuration.
This is a result of my trial and error.

I hope this helps Embench users.

@hirooih Nice work. I've again asked @PaoloS02 to review, but this is a good addition.

Do you have any results you can add to the embench-iot-results repository?

[hirooih]

Thanks.

Do you have any results you can add to the embench-iot-results repository?

I can create a result in minutes.
But as I wrote in the README file, I made no performance tuning.
For example, the FPGA configuration fetch instruction from slow external NOR memory, and it has very small I cache size.
I use only -O2 -Os for compiler option.
I think it is not fair to send my result.
I hope Sifive guys will provide better configuration and its result.

Are these supposed to be removed?

[PaoloS02]

I mean "args" and "environment"

[hirooih]

You are right. The two lines are useless for execution environments on FPGAs.

Instead, it's better to add the following line.

See Configuring C/C++ debugging for more configuration options.

@PaoloS02,
Thank you for reviewing this PR.
Is there any concerns in this PR?

BTW I have some updates to this PR.
Which is better for you, 1: open an separate PR or 2: add commits on this PR?
