You can build and boot the kernel under qemu for several architectures
(including sh4) by following the instructions on:

  https://github.com/landley/mkroot

I believe I last built -rc6?

You may need the attached patch to fix the serial port issue from:

  https://www.spinics.net/lists/linux-serial/msg26085.html

Which is still there because the kernel guys don't care that they broke
qemu, and the qemu guys are still using old kernel versions that work
fine. My patch just reverts the kernel change (which enabled hardware
buffer logic qemu doesn't implement).
