Dear Marek Vasut,

Yes, I know. Hmmm, maybe if every 24 hours the auto build infrastructure:
- Runs a MAKEALL on the mainline repo (if any patches have been committed)
Certainly ... it takes 16 hours to do so on my dedicated machine though (more now, since I started building sparc too ;-D ). But WD has some pretty badass machines that can do it really quick :-)
Not nearly quick enough for all arches and all boards and and all repos...
- All patches applied to sub-repo's (i.e. do a git-pull of eachsub-repo) - If the mainline MAKEALL is clean but the 'patched' MAKEALL is not, use git bisect to identify the first patch that breaks the build
Hm yea ... serverfarm needed here. Badass machines and badass cluster is a difference ;-)
Sponsors needed to pay for such a infrastructure...
You have c) twice in there (nit :) ). Still, we'd need a pretty badass buildsetup for that, right? But indeed, such an algo sounds nice.
I wish we had unlimited resources...
But then - U-Boot is _much_ smaller than Linux, and they do not do anything like that, yet they manage to keep going. What are we doing wrong / differently?
I think it boils down to community size. There's a lot of people building and testing random combinations. There's just not much of that today for U-Boot.
