AMCC 440SPe support?

Are patches to support the AMCC PowerPC 440SPe processor available?
Mainline 2.6 apparently does not contain anything related to the
440SPe.  We're planning on using the 440SPe in a project, and I'm
wondering if I'll have to do the bringup myself.

If no one has released this yet, I'll be happy to start posting
patches once my eval boards arrive.  I just don't want to duplicate
effort if someone has already brought up Linux on the 440SPe.

Thanks,
  Roland
