Are you talking about DEBUG_UNCOMPRESS?
Should I read the sentence as "even if DEBUG_UNCOMPRESS is not selected,
some board will continue to print information during the uncompress step"?

Isn't this a bug in the platform specific code that should be fixed anyway?

I am not sure if this is the right solution to the problem.
I think it might be better to add the appropriate ifdefs into the
platform specific code.

Arnd, what do you think?
