BSP For SCP124 (7448) PPC

[Bullock, John T. (JSC-ER7)[L-3 COMMUNICATIONS CORPORATION]]

I'm a completely new to RTEMs, so forgive me if this has been asked before, I didn't see any of this type of board in the BSP wiki.

What is the best BSP for the Curtiss Wright SCP124 (7448) PPC board for use with RTEMS?

They have a YellowDog, VxWorks and their own linux development kit BSP.

Or is this just something we'll have to build up?

Thanks
