  The patch implements barrel shifter using rotate as a main primitive.
  The design was optimized for Altera Cyclone III FPGA and can be reused
  with other FPGA vendors and products.
  The patch integrates the FPGA-optimized barrel shifter into the
  Amber 23 core when it is build for Altera FPGA.
  
  The patch reduces footprint from 1178 to 339 LEs keeping Fmax at 57-60 MHz.
