Add support for VCU118

[cassebas]

Hi Eugene,
At work I can use a VCU118 FPGA. Could you add support for this board?
Or, if you give me some pointers on how to add the necessary files/configuration, I can try to add support myself.
Thnx!

No, I don't have the board.

if you give me some pointers

You need to add board/vcu118 directory with board support files.
Use other board directories as example, board/vc707 would be most suitable in this case.
Copy files from board/vc707 and changed/rework them for the new board.

I am working on reworking the vc707 board files and make them work with the vcu118. I have a question about the memory interface. I see in the board/vc707 directory several .prj files that I think are generated by the MIG tool within Vivado? I want to try and generate these files for the vcu118, but the memory on the vcu118 is DDR4 instead of DDR3. Is this a problem? For example, the user guide of the vcu118 talks about 80-bits wide interface to the memory modules.

Will the rocket core be able to use DDR4?

No, it is not a problem.
You can use u200, u250 or vcu1525 boards as example, they also have DDR4.
