Allow for variable DQ/DQS ratio #300

Closed RRozak closed 2 years ago

RRozak commented 2 years ago

This PR adds the possibility for variable DQ/DQS ratio. I saw that there was handling of 4x, but this approach is more general and I think it is simpler.

I noticed that it may require some further changes. I will mark as ready for review when I check and possibly fix.

Thanks @RRozak, ok please update the PR when you think it's ready.

I think it is ready. It also requires a change in litex: https://github.com/enjoy-digital/litex/pull/1258
