the console banner and the option table will never be updated with more
recent build.h strings.
Thanks to Mart Raudsepp for spotting this oddness.
x86emu doesn't care about the contents of build.h, it just uses build.h
to check whether it is compiled in conjunction with coreboot.

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.

- Remove obsolete comments, fix incorrect ones.
- Use the full/canonical name of mainboards/vendors everywhere.
- Update the list of USB Debug capable chipsets from
http://www.coreboot.org/EHCI_Debug_Port.

r785 (move from explicit asm to implicit C) and unfortunately qemu never
triggered the bug, only real hardware did. That's because qemu will not
spew an error on access to RAM before RAM is enabled.

This code has been tested on dbe62, and builds for qemu as well.
the next step is testing on simnow.
k8.h: add more prototypes and some required inline functions.
cpu.h: same
serengeti: expand defines in mainboard.h, though we need a better
mechanism; continue to fix initram.c, add new support files to Makefile
lib/console.c: include globalvars.h
lib/lar.c: Provide more informative print as the lar is scanned.
k8 north: needed reset_test.c from v2, fixes to raminit.c
arch/x86
Kconfig: new CONFIG variable CBMEMK, meaning coreboot mem k, memory
used for coreboot.
init_cpus.c: functions to start up CPUs
stage1_mtrr.c: bring over early mtrr support from v2.

Adding a new global variable is not as easy as it looks, but the
comments in the code should be good enough to tell you how.

(1)we now compile in all printks, which is good: we can print any message provided we can change
the console log level at any time.
(2) The console log level is compiled in and unchangeable, which is bad, as it defeats the purpose of (1).
Add a BIOS_ALWAYS log level. Make console log level a variable. Make functions that set it and get it
visible everywhere. Always print out the version message; this is really *not* noise!
PCI: Simplify pci functions so that they can be used in stage1 or anywhere for that matter. Add
a find function which is needed for many stage1 functions. Note that we copy but also clean up
the libpayload stuff just a bit.
Get rid of config space type 2. If there was ever a platform that used it, I don't know what it was,
and the presence is a needless distraction.
tested and working on DBE62 (which means the console and the pci functions work :-).
There is a remaining problem with dumplxmsrs which nobody understands. It prints out garbage if we use the
%s for the msr names.
Formatting is an issue; if somebody wants to fix formatting they can assume I will ack it. Sorry,
my emacs has gone just nuts.

Tested on Qemu and Geode LX.
Benefits of this patch:
- printk() now works directly after printk_buffer_init(), even before
the serial port is set up.
- If all you want is a log, you don't have to bother with serial output.
- A payload can read and analyze the log.
- You can build on this and buffer log until serial is available, then
flush the messages buffered so far.
The printk buffer is configurable with a default-on Kconfig variable.
If you want to dump the buffer from the Qemu monitor after CAR has been
disabled, use this command:
memsave 0x90000 65536 memdump.bin
