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:
coreboot-3.0.986 Fri Nov 7 04:04:37 CET 2008 starting...
(console_loglevel=8)
Initial lowest stack is 0x0008fe98
Choosing fallback boot.
[...]
Done RAM init code
After RAM init, lowest stack is 0x0008fe30
Done printk() buffer move
[...]
LAR: load_file_segments: Failed for normal/payload
Before handoff to payload, lowest stack is 0x0008bf50
FATAL: No usable payload found.

smbus.
Set up a global var variable called spd_inited. It is set when spd is
inited.
For simple cases, nothing is visible to initram main. For complex cases,
initram main can do the work and set this variable.
This compiles and runs on dbe62, which is actually meaningless since
dbe62
has not smbus, but hey ...

processor BIST is nonzero. Checking it in initram makes no sense. Having
it as global variable is unnecessary as well. Link BIST is an entirely
different animal.

We need the sys_info struct in the global variables struct for
cache as ram on k8. The sys_info struct is generally very useful
so it makes sense to start accomodating it.
This patch adds an (empty for now) sys_info struct for geode.
It add sys_info to the global variables struct.
It removes global variables from console.h to a new file,
globalvars.h. Very little code needs to include this file.
This patch is tested on the dbe62 and simnow with no problems.
k8 compilation is now broken but I'm working on it. I'm going through
the eyeballs-bleed code on k8 startup to document it and with any luck
we'll have more functionality by the end of today. But it's hard ...
