What about the nop instruction? Should I add a conditional macros in
the init.c file, or create a new macro to mirror l.nop to nop for or1k
targets?

Thanks for pushing the code.

How can I get this? Is there a script for running all tests or
something similar?

Ticker is running but there are still two issues. The first is with
the very long delay of context switches. The second is about the
printf and the possibility of broken context switch (which I debug
currently). To get around the printf problem, I was adding an entry in
buffer_test_io.h for or1k target to force tests to use printk. Gedare
suggested not to push such a solution.
