This causes the dmi wrapper from SweRV EH1 and SweRV EL2 to have
the same interface which makes it easier to use the two CPU cores
interchangeably in a design.
not start an SB write access when sbreadonaddr/dbreadondata is set.
Add fpga_optimize option to swerv.config; eliminates over 90% of
clock-gating to support faster FPGA simulation.
