This is indeed an important project. Unfortunately, after discussing it 
with another
core developer, we think it may be beyond a GSOC project.

First, it requires deep knowledge across RTEMS, boards, target 
architectures, etc.
We are afraid that by the time we mentored you enough to solve the problem,
(1) we could have implemented it and (2) the summer would be over. :)

Another factor is that a couple of the core developers are currently
supposed to be funded to do this as soon as they finish up another project.
Based on the schedule, they should be nearly finished before the GSOC
students accepted are announced. They are only committed to implementing
the BSP/target side of this for a couple of architectures.

This leaves you the option of proposing to implement this for the remaining
architectures. But it also puts you down stream of another schedule which is
a risk.

I wouldn't want you to be at risk of even starting on time. Is there another
project you would like to do?
