contributing new port?

[Bob Wilson]

Tensilica has ported newlib to work with Xtensa processors.  It seems like it 
might be a good thing to contribute our port.  What is the process for this?  
I'm wondering mostly about the copyright issues & etc.  Since newlib is 
maintained by RedHat and not FSF, I assume we don't need to assign our 
copyright to the FSF.  Judging from COPYING.NEWLIB, it looks like we need to 
release our code with some sort of free software license -- any particular 
requirements?
