Copied over preliminary Konata support from 89b0c37a7b
...
The referenced commit did not merge well with our code base. Therefore, I copied over the changes manually. These changes do
not constitute a working Konata support for Toooba. In this commit, I commented out some things that did not compile, which will be fixed in future

This will be very expensive in terms of area and possibly timing.
Ideally this instruction would be multi-cycle or optimised to reduce the overhead.
