What do you guys need me to do to release the code?

Add copyright notices to all the files I patch?

Push it into a GIT tree?

I got a port (minus Ethernet, which I didn't need) on the TS-7200 when 
it first appeared around 4 yrs ago. The lack of JTAG makes it a little 
painful, but it's do-able. That board used Redboot, so there was a good 
starting point. Contact Technologic to see if they ported Redboot before

switching to the Linux quick-boot. If not, compare the Redboot ports for

the other Technologic boards to see how their hardware tends to differ 
from the Cirrus eval board(s).

I couldn't submit my port because it was based on the Technologic code, 
which was based on the Cirrus code. I tried to rally Cirrus to submit 
their port, but got no response.  I eventually just handed my port to 
Technologic, hoping they could resolve it. I gather Cirrus made 
significant improvements to their port in the intervening years.

But Brian Austin works for Cirrus. Right? Any news, Brian?
