Defintely. I haven't seen anyone in this thread blame Russell for the
mess. As far as I'm concerned, the code in arch/arm consists of
the well-maintained {mm,kernel,lib,common,tools,include} directories
that are actively being taken care of by Russell, and a huge amount
of crap that has accumulated in mach-* and plat-*. Some of it is
arguably better than other parts, but the problem is not that someone
in particular did a bad job writing the code. The problem is that
nobody today is pushing back hard enough on crap getting added.

There is a lot of good work going on to reduce the amount of crap in
the mach code, but my feeling is that it's not keeping up with the
rate of crap getting added by other people. In some ways, the Linaro
project has actually made this worse by helping people get their code
into shape for inclusion (which of course is generally a good thing
to do).
