Hi Andy, 

Here are 3 patches for smem/hwspinlock which I have tested with QDSP on IFC6410.
Also a fix from Ivan which I think can be taken aswell.

Thanks,
srini

smem needs to be outside the soc as there is no reg entry.

This patch adds the shared memory in the Device tree reserved memory
list so that kernel would not map it as normal memory.

As far as I can tell my patch for adding smem and hwmutex are already in
