I’m ready to provide source to individual testers, but not to publish 
it yet.  For anyone that wants to try it, I can provide source and maybe 
a kernel; I’m not set up to do full images.  I’ll also note that 
I’m testing using a kernel that is not recent, because it boots with 
my current u-boot, but I suspect it will work fine with a recent kernel.
