Iyonix, Shark, Netwinder and Cats are all pretty much complete systems 
(PC's if you wish, except for the different CPU).  They have video, 
keyboard, mouse, disk and in most cases PCI/ISA slots as standard.  They 
are also generally supplied in boxes with power supplies and all the other 
necessary baggage for you to plug them in and use them.

I don't know anything about the board you've done a port for, but if it 
fits the above criteria, then I'd suggest it warrants a 'port' of its own. 
 If not, then it probably belongs as a sub-port of evbarm.
