Allow me to disagree, although I'm biased because I'm the one driving this.
I've added some very minor initializations which were missing. Speaking about
code size, this is a few bytes.

You can argue that this is still extra code not needed in the "regular" use
case, but for the same reason we would have to kick out most of the
initializations which Rockbox does, just because that's already been done by the
initial firmware. However, this would make us very dependent on the firmware
behaviour. If one day Archos comes out with an updated firmware and we rely on
their settings, Rockbox may not run any more. I'd prefer to do the full set of
inits and be independent. The latest "cold start" experiments just revealed
some oversights in the present inits. There's nothing flash-specific about
this.

However, there will be a few lines or in the future, when I start looking
for ajbrec.ajz in the root and rolo that. But still I don't like a compile
switch for that, instead I will detect the cold start and decide at runtime. We
have in my opinion too many different builds already, the difference is very
minor.
