This is a complete rewrite of my earlier stack checker proposal.
It works for CAR and RAM, has better abstraction and actually gives us
nice results.
The stack checker is default off due to its rather measurable impact on
boot speed.
Diagnostic messages are printed on first initialization, directly after
RAM init and directly before passing control to the payload. Sample qemu
log is attached. Extract from that log follows:

While I was doing that I moved the checks for CONFIG_<BUS>_PLUGIN_SUPPORT to

have a CAR area outside the usual RAM area. For those processors, we
have to implement a stack copying and switching mechanism. Since gcc
can't be told that the stack just moved, split stage1_main() into
stage1_phase1() and stage1_phase2() and stage1_phase3().
stage1_phase1() is the new entry point in stage1 and will handle
everything up to the point where we want to disable CAR.
Switching the stack, disabling CAR and handling other tasks related to
the stack switch (printk buffer move) is all wrapped in the
stage1_phase2() function.
stage1_phase2() calls disable_car() which then calls stage1_phase3().
stage1_phase3() is the former second half of stage1_main().
Notes about this patch:
- Code flow is almost unchanged for Qemu, K8 and Geode. No extensive new
testing required.
- We can support stack-keeping and stack-relocating architectures at the
same time, so C7 is definitely supportable
- The comment in stage1_phase2 says "some of this is not yet done". That
refers to the nonexisting code for stack switching on C7.
- "Minimal changes, maximum benefit".

are welcome.
