The pre-boot code cannot be created from only the specification. It is
   often the single place where the many variances found during
   manufacture that roll-up erratas and internal memos by the manufacturer
   and fab.

     No, if the CPUs were truly open, proprietary boot code
     would be completely mooted just write your own to spec.
     Only stupid sheep and order takers would continue using
     closed shit.
     Yes there are no truly open CPUs, nor open Fabs, that's the problem.
     It's easily fixable, and extremely profitable for the first players
     to do it.
