That's not really comparable. Raspberry Pi added entirely separate RISC-V cores to the chip, they didn't convert an ARM core design to run RISC-V instructions.

That's not really comparable. Raspberry Pi added entirely separate RISC-V cores to the chip, they didn't convert an ARM core design to run RISC-V instructions. What is being discussed is taking an ARM design and modifying it to run RISC-V, which is not the same thing as what Raspberry Pi has done and is not as simple as people are implying here.
