As far as I know, there's no way to run rtems without a bsp. Having the 
processor core
supported by RTEMS is a good sign, and a good starting point.

For your given ARM SOC (system on a chip) you'll need to find the 
appropriate bsp. If one
does'nt exist, then one will have to be written (obviously).

Taking a quick look at the wiki, I'm not seeing one for your part. Maybe 
I missed something.
