Yes, that makes sense. I think nds32 was always going to be a short-lived architecture as Andestech was already in the process of moving to RISC-V before it was ever submitted upstream. I did hope that it would live a little longer, but it seems that everyone who ever worked on it in mainline has left andestech by now. I'm guessing Nick's current email address based on his Linkedin page, maybe he can contact someone who is still there and able to take over. I think nds32 is still in a better shape than a lot of the older architectures in mainline, and the CPU cores are still actively marketed for licensing. OTOH it only gets worse if nobody cares about the code, and users are probably already better off with one of the older longterm supported kernels. If we remove arch/nds32 before the next longterm release, that gives users stable updates until late 2026 using linux-5.10.y, which is probably sufficient. Arnd
