Ok, I've applied this on the previso that _no one_ in future whinges if
the debug infrastructure doesn't quite meet their expectation.  The
debug infrastructure remains first and foremost that: a simple debug
infrastructure suitable for use in the early assembly and the like.

That is its primary concern and trumps any requirements from consoles,
early printk, decompressor output, and the like.
