Describe CVA6 for write-through and write-back cache versions
In #602, there was a conversation like this:
Is the list of files in the manifest complete?
Looks okay for the write-through cache version. Of course, the write-back cache needs different files.
AFAICT, the ability to compile CVA6 for either write-through and write-back cache versions is not described in the User Manual. The User Manual should be updated to explain:
- How to compile the CVA6 for write-through and write-back cache versions.
- Theory of operation for the write-through cache controller.
- Theory of operation for the write-back cache controller.
