Is the "or32" target still supported?

My investigation thus far indicates that the OpenCores project certainly 
doesn't appear to be dead.
However, as far as RTEMS support goes I am getting a number of leads in 
different directions.
I do sense from their web site that much of their effort now is directed 
towards uClinux.  

Here's a recent post that looks promising response I received:

Hey !

or32-rtems is not maintaned daily since you could build RTEMS with
or32-uclinux toolchain.


This is the direction I'll investigate next.
I'll let you know what I find out about building RTEMS for the or32 core.
Thanks for responding.
