Description
The Zbkb subset of the scalar crypto extension is already mostly implemented as it draws from unratified v0.93 bitmanip which we have implemented.
Major task here is to compare the Zbkb specification against our existing bitmanip implementation and see if there any gaps/differences to address.
Then we need to setup appropriate parametrization So Zbkb can be included/excluded.
Verification will also be required, as with the RTL much of the pieces are in place it just needs organizing under a Zbkb configuration option.

Research direction
Compare the Zbkb specification with the existing v0.93 bitmanip RTL to identify gaps or differences. Then trace the current bitmanip configuration and verification paths, organizing the existing pieces under a Zbkb inclusion option. Done means Zbkb can be enabled or excluded and its behavior is verified.
