[ECOS] port ecos to blackfin

[Bob Amstadt]

I'm also interested in a possible Blackfin port of eCos.  A quick search 
shows that people have asked about it, but I am wondering if anybody has 
put any work into it?  I'm currently running uClinux on the Blackfin, but 
eCos would be a much better match for my application.  Unfortunately, I 
don't currently have the time to tackle porting eCos on my own, but I could 
assist somebody that has started the project.
