Per discussion with YingHai Lu, we are only going to support F2 and
later CPUs. This will simplify more code.
I realize this code needs work, but it is in v2, and cleanup will get
easier once we have the baseline.

simply hope they are unused/empty and will get runtime crashes/
corruption/malfunction if they are not empty. Same applies to any
sections with relocation entries which can not be resolved during
link time.
Check for the emptiness of these sections and abort the build on error.
This triggers on all stage1/initram global variables which are not
declared the right way. It also triggers on local static variables.
Features of this checker:
- It doesn't only check for non-empty .data and .bss, but also for
unknown sections which would be a problem.
- It gives you the offending filename, the section and the variable
name.
- It won't stop after the first error and will tell you about all errors
for a given file list.
This found a long-standing bug introduced in r729 and fixed in r786.
It also broke the build of every Geode target in the v3 tree because
they had multiple bugs. And it broke the build of the K8 code because
of a bug there.
Other fixes resulting from this checker are in r790 and r791.
Ron already fixed some of the bugs uncovered by this checker.
Tested for all possible variations of .data and .bss usage.

This one is far from obvious, so let me explain:
Basically, *msrnames[] is an array of pointers (strings) and pointers
need relocation. That's why they end up in .data.rel.ro.local and make
lots of trouble.
This should fix the crash Ron was seeing when register name printing was
enabled.

Continue to upgrade northbridge for k8.
Add a new standard include (which is optional on some chipsets),
mainboard.h, which will define important mainboard constants that
1. do not belong in dts
2. do not belong in Kconfig
3. are so tightly tied down to the mainboard they should probably not be
visible, i.e. the value of the variable is defined by artwork on the
mainboard, such as the socket type.
This file resolves the long-standing question of where certain
mainboard-dependent, compile-time control variables belong.
We've not resolved this issue in two years so here's how
we're going to do it. The first use of this is in the definition of
CPU_SOCKET_TYPE, needed by the northbridge code.
These changes do not affect existing Geode builds (tested on DBE62).

Introduce EXPORT_SYMBOL for shared symbols. EXPORT_SYMBOL tells the
compiler to use the standard calling conventions for a given symbol and
not to optimize it away.
Benefits:
- We can later use gcc -combine -fwhole-program without problems.
- It's a correctness fix for some optimizations.
- We could check for duplicated exported functions at link time.
- We could check whether exported functions are linked into initram or
stage2 by accident.
- We could generate usage statistics and possibly optimize away unused
shared functions.

Calling non-PIC code from PIC code needs an ABI wrapper and we don't
provide one. Our trick with function pointers is exceedingly fragile:
- it depends on gcc not being clever enough
- it forces us to compile all initram source files in one go
- parallelizing initram compilation breaks the code
- compiling one initram source file at a time breaks the code
- enabling higher optimizations breaks the code
- enabling -fwhole-program breaks the code
- declaring the function pointers const breaks the code
- it's an undocumented side effect of gcc which will go away
- we need excessively ugly shared function wrappers
- the shared function wrappers had more than their fair share of bugs
- almost nobody understands the wrappers completely
- Segher warns against them: "So why do you think this should work?
You're telling it to link PIC to non-PIC. Did you read the manual? It's
just not allowed. It cannot ever work."
Kill the SHARED wrappers and use a real ABI wrapper.
The wrapper code is autogenerated on demand.
Any function compiled into stage0 is now shared by default, yet the size
and code generation of stage0/1/2 code are unchanged. Initram code size
does decrease quite a bit and the difficulty of creating shared
functions is now zero.
The patch includes extensive documentation about the inner workings of
the new wrappers and the reasons why they look like this.

But we can start to build it now.
Add the serengeti. Now comes the fun part: trying to get it to build.
Be aware that things have changed.
Stage1 is going to need to start up the APs, load the microcode, before we can event attempt to run initram.
So we're going to need more sophisticated code than we've had in the past.
Note also that copying cache_as_ram_auto.c and hacking it is NOT an option. We're going to have to
recreate stage 1 and initram from scratch. I expect this to improve the code anyway.

This changes SPD_NUM_COLUMNS from 0x8 back to 0xa, as it was originally when
copied over from another board, because 0x8 evaluates to 2kB, not 8kB, while 0xa
does the latter. 8kB is what the chip has and what is also set in our currently

while before it would freeze or reboot just into 50% of first test.
