This is very interesting topic to me. I just received few days ago pandaboard, which is somehow successor of beagleboard and it is built on TI OMAP4430 SoC.
Main difference is that this one is dual core ARM Cortex-A9 so it needs SMP support. I guess that so far there is no SMP in ARM implementation on FreeBSD so I planed to spent some time on it. 
Is there any work done so far on SMP side? 
If not is there any wider interest to implement ARM MPCore in FreeBSD?
Any other thoughts on this topic?

Thanks,
