Rewritten Book for Architecture RISC-V#170

It would be very interesting that this book was rewritten for the RISC-V architecture, it has grown and widespread used in technology courses, in addition to being easily used with small FPGA. I am already building my own processor, although my focus at the moment is a microcontroller, once I reach my goal, I will move on to a new phase which is to build a slightly more advanced processor that can be used by an operating system.
