Adding support for other CV32-based cores

[pcotret]

Hi,
I'm currently working with cores from the CV32 family. I'd like to add support for it in LiteX.
As far as I understand from the CV32E40P PR (#535), I need to:

• Modify similar files
• Add configuration in pythondata-auto
  And it will create in a way the pythondata-cpu-cv32*** repo structure.
  Am I right?

Yes, that is correct. I will create the pythondata-cpu-cv32*** repositories for you after you send the pythondata-auto patch.

Just to be sure, for preliminary tests before the PR, I assume that I should create the pythondata-cpu-xxx repo by myself.
pythondata-auto will only be used once I've pushed things here.

Is it correct?

You don't need to create the pythondata-cpu-xxx, just send a pull request to pythondata-auto and I'll create the repos.
