Reading the AM3359 Docu (this is the BBB's chip) it has an "Arm Cortex 
M3 Subsystem" (other then the predecessor AM17xxx that had a PRUS with 
a  TI propriety CPU design). So it seems to be "a standard Cortex-M3 core".

Of course the RTL will need some squeezing to make it work for the PRUS.

I found that there is software to set up the PRUS using the Linux device 
file system (and they tell us how to do software for the PRUS in ASM).

So this should be doable.

Thanks a lot !
