Well actually (I think) we agreed on doing the board/vendor scheme.  For
example look at board/amcc - there are all the AMCC evalboards basically
each one with a different SoC.  Turning this around into board/<soc>
would throw pieces all over the places, which is definitely not what we
want.

Let's look at it from this perspective - on a board level there is
really more adhesion between two different cpu boards from one vendor
than between two same cpu boards from different vendors.  Just take the
AMCC boards - they all have the same feel to them, so this is the
natural way to group the boards.

Even more, sharing of stuff should be done outside of board/ - if it
applies to all omap3, common stuff should be in cpu/arm_cortexa8/omap3
and *not at all* below board/.

Finding boards with the same architecture was always very easy by
grepping the include/config/* files.  We do not need a representation of
this fact below board/.

Although I think that these arguments carry some value, I know that
one can come up with - basically arbitrarily many other arguments.  But
still, we had this discussion already and I do not see that anything
fundamental has changed since the last time around, so please let's not
got into bike-shed painting right now ;)

Cheers
  Detlev
