Oh, right sorry, this slipped my mind.
The userspace (busybox) that comes with my smp branch makes use of the
atomic instructions, and I assume that your or1ksim is not built from git
HEAD?
Anyway, you can either update your or1ksim (and remember to use a recent
version of mor1kx that has support for these instructions when you try on
the actual HW),
or just copy the userspace from e.g. Jonas repo (everything in
arch/openrisc/support/).
