This is the result of this discussion:
https://lkml.org/lkml/2020/6/2/203
RFC because there are still some TODO items:
- I haven't added VCAP fields to Ocelot and to Seville, mostly because I
don't understand how to derive the ENTRY_WIDTH setting. Would
appreciate some help there. I've only tested this on Felix.
- The selftests script is rather bare bones, not sure what to add to it
to make it more comprehensive. Understanding that this is the go-to
reference for any user, it would need to be pretty clear how the thing
can be used.
Comments appreciated.
