Hi,

Thinking about it, I turned it not into a rule, but into a Lemma from
the 10 rules:
Lemmas from the golden rules
1. Generic Code is Good Code
New code shall be as generic as possible and added to the U-Boot
abstraction hierarchy as high as possible. As few code as possible shall
be added in board directories as people usually do not expect re-usable
code there. Thus peripheral drivers should be put below "drivers" even
if they start out supporting only one specific configuration. Note that
it is not a requirement for such a first instance to be generic as
genericity generally cannot be extrapolated from a single data point.
Feel free to amend / modify that.
Cheers
Detlev
