This is an example of a "BSP variant". The base bsp is gen83xx and
it supports a variety of actual boards. You want

This sounds like you do not have the RTEMS tools installed
and at the head of your PATH.

Ahhh... 4.8 doesn't have this BSP. You will have to check
out the 4.9 branch or head from CVS.
It should work nearly all of the time. Thanks to Thomas
Doerfler sending me one, it gets tested fairly frequently.

You just happen to know that the mpc8313erdb is supported
but it was added after 4.8. :)
