IMNSHO, it's time to pull the plug from the RTEMS nios2 port.

It's a pity for its users and a shame in general, but I feel we have 
been patient long enough.

We have demonstrated our good-willingness by keeping the nios2 port 
inside of the RTEMS source tree and invested time into keeping it alive. 
However everything has to come to an end under circumstances like these.
