Many thanks to > the community as well. Ok, sounds like it can indeed get phased out then. How would you like to proceed here? Would you send a patch to remove arch/nds32 and all the associated driver code that is no longer used with your RISC-V based targets, or would you first update the MAINTAINERS file to list yourself and pick a date for the final removal? Either way, feel free to send me patches to pick up in the asm-generic tree. Arnd
