[U-Boot] Policy for checkpatch usage?

Hi Scott,

So you would agree to this text:

  Checkpatch is a tool that can help you find some style problems, but is
  imperfect, and the things it complains about are of varying importance.
  So use common sense in interpreting the results.  Warnings that clearly
  only make sense in the Linux kernel can be ignored.  
  
What about the problem with checkpatch errors in current code, i.e. the
origin of this sentence:

  Also warnings produced for context lines (i.e. existing code) rather
  than actual changes can also be ignored.

Do we want this?

I agree 100%, but I also understand that people want to see some
guideline that they can refer to.  So let's see how good a compromise we
can find.

Thanks
