nothing has been mandated.  we're simply a bunch of devs throwing around 
random ideas to try and make u-boot more resilient to free flowing changes 
that git development enables.  a method to quickly validate user contributions 
is great as we can then say "you have to verify your change against the XXX 
test".

i too would prefer a POST case that can be classified as a mathematically 
sound proof.  did i miss something, or was such a case proposed ?
