I still have to ask you for that driver, so yes I am interested in
the patch ;-)

... which has been the main obstacle for me to integrate turtleboard
in my regular kernel testing workflow. There are only 24 hours in a day,
so usually there is no time left for juggling SD cards :-(

Does kexec work on MMU-less J2?
On SH4, there was never an upstream kernel that worked with upstream
kexec-tools. The only one that works is the kexec binary from the old
landisk distro, which predates SH support in upstream kexec-tools,
and can only start a new kernel from a system that is running kernel
2.6.22...

BTW, this is seriously off-topic for openrisc and qemu, so please
reduce the CC list when continuing the linux-sh discussion..

Thanks!
