  Hi Adi,

  Just today we were discussing on the Buildroot Developer Day what a 
pity it is that there are so many buildroot forks and that we never hear 
from them. So first of all, thank you for joining the list!

  Forking a fast-moving project like buildroot, making 615 patches to it 
and then expecting it to merge smoothly after two years is a fantasy :-)

  Although there are other paths such as rebasing or incremental merges, 
in the end you'll just have to resolve the conflicts. But probably many 
can be resolved by just checking out the buildroot version ("git checkout 
origin/master Config.in").

  You'll also have to slightly rewrite all your packages, because it is 
no longer $(eval $(call AUTOTARGETS,host)) but it's $(eval 

  For changes you think could be relevant to the buildroot community as a 
whole, you could also consider upstreaming them first, so that during the 
merge you can just resolve to the buildroot version. For the future, my 
advise is to upstream more often (certainly whenever you're touching a 
package that already exists in buildroot, and preferably also for new 
packages), and to merge more often (for instance every buildroot release).
