I'm not sure why you are trying to convince me to kill off support for SuperH
boards. I have just stepped up maintenance of arch/sh to keep SuperH hardware
supported in the kernel because I have been a maintainer of Debian's SuperH
port for several years now.

There is also a small community of SuperH enthusiasts now hacking on the kernel
which is coming together for discussion in #linux-sh on libera IRC.

Thanks,
Adrian
