I'm sorry, I think this crap has to go. Trying to make it fit every
platform in one kernel is just too complicated. It _needs_ to be
something so damned simple that it always works without fail, every
single time someone wants to use it.

The current code really hasn't a hope of doing that.

Yes, that means you only configure it when you're not building a multi-
platform kernel, but that's worth giving up if in return we have something
that is 100% reliable.

As it is, I need to invent new debugging code to debug this mess. Sorry,
I'm actually not going to bother - as the LL debug stuff was my debugging
code to debug exactly these kinds of boot problems. Someone else can have
the pain of sorting out this breakage, and tell me when they expect OMAP
to work again.
