This is a good board, and Alan pointed out he has some basic support.
This board would not support SMP though.

There was a GSOC project by Xi Yang last year that did an initial SMP
support for ARM. That code should be merged soon we hope. From there,
lots of projects are possible w.r.t. SMP. it depends what level you
want to work in: add support for more ARM CPUs to use SMP, improve SMP
capabiltiies like Atomic operations for ARM or implement an SMP
scheduler, and so on. The first thing to try to do I suppose is to
attempt to replicate Xi's work if possible.

The IRC channel is on the freenode irc server, then go to #rtems channel.

I'm working to get a memory management framework in place. It is
rudimentary, but last year's GSOC we had a student who got the initial
framework to work on the PSIM simulator for PowerPC and Skyeye
simulator with Gumstix BSP. There will be plenty to do with this
framework, including to add more BSPs, generalize shared support for
CPUs, and work on improving the internal memory management interfaces.
