f59b4ca24a This patch removes the offset_pciio since there is never an offset_pciio an
offset_pciio and an offset_io.  This makes it easier to port things from v2.

It also updates mcp55 and some whitespace there.

68529567e4 This patch:
* Moves non-DRAM early init code out of initram and into stage1, where 
it should have been in the first place
* Fixes an issue with GP3 timer causing system reboot (possibly not 
present in current svn, but was present in my local copy)
* Fixes serial garbage from stage1 on jetway j7f2
* Fixes ROM mapping for flash > 512k on vt8237
* Makes a couple minor whitespace changes
* Moves some function prototypes to the headers where they belong
* Nukes some phase2 hackery that belongs in phase4 (eventually)
* Comments out early_mtrr_init() for via/epia-cn, this breaks booting on 
jetway j7f2
* Moves troublesome SATA init code into stage1 - change of device class 
hangs coreboot
* Gets to vt8237 IDE phase6 init and dies on jetway/j7f2:
	Phase 6: Initializing devices...

cb9db3b6d0 We are woefully unaware about how much stack v3 really uses.
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

Before handoff to payload, lowest stack is 0x0008bf50

8b1b420e6b We need a way to find out where our stack and our global variables are

processor-specific way behind the scenes if needed.

33de3b2fb5 Right now we face the problem that we can't support processors which
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".

be03d189db Finally, after two years, put in real code for stop_ap(). Code has to be
moved to stage1 ROM code. Make the struct for nodeid/coreid generic to 
x86. Create the functions for existing architectures are a model for 
future architectures (VIA coming soon we hope). 

Move includes so that things build correctly now. 

This is actually a small patch that impacted a number of files due to 
include order changes. This is build and boot tested on simnow and 
build tested on geode.

e053a1004c substantial cleanups for k8.
AMP TinyGX still builds, this won't affect other platforms. 

clean up 8111 stage1 code; add function to smbus, 
memreset_setup_amd8111, for the 8111 specific parts of memreset. 

include k8 .h to reduce warnings. Turn some things into functions (romcc
legacy cleanup) and put them in .c files. 

simnow actually successfully gets through a reset cycle now. 

Next is to fix the fidvid code.

ff2ddcb313 This gets us back to a compiling k8 target.
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.

f365719d09 This is closer! There are < 10 functions to be worked out, so most of
what you get are warnings. 

There is lots of room for improvement as we move to all CAR 
code, but that will take time. 

I hope to get this to really compile over the weekend. 

At the same time, if anybody wants to take a crack at it, your efforts

96e0fd18bf Fixes to make k8 and others work.
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 ...

62f8ea8e9b This set of changes gets us much farther, in fact, we get into initram.
This means that basic resource maps are working, initial hypertransport 
setup is working, the amd8111 ISA device is working, config space is 
working for all the parts, we can grow the FLASH part address space to 
more than 64k, and in general we're having a good time.

784450567f This now compiles and has a simple error on build to stage2.
Geode still builds fine. 

include/lib.h includes a new function, cycles(), which is a u64 and 
architecture-defined. (Thanks, Plan 9, for a sensible idea). 

All rdtsc removed in favor of cycles()

All other changes are k8 specific. None of these changes adversely

4110e67004 Add ddr2 defines.
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).

7102949d76 We're much closer.
Added a stepping enum to k8.h. This will allow us to do things like this:
if (cpu_stepping(node) < E0)

and so on instead of is_cpu_pre_e0_in_bsp or whatever it is. 

Added and fixed Kconfig variables. 

Broke out northbridge by function, so we can see what goes with what. 

This tree still builds a working DBE62 coreboot that boots a kernel; no harm done to existing ports.

9342d1be4e The ABI wrapper from r775 made the SHARED definitions obsolete. They're
not that readable anyway, so kill them and use standard definitions
instead.

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.
- Through the above points, significant side reductions of 10-40%

649c9f99ff Console:
(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.

54b7a9609f With a bug fix from peter and a suggest change by Carl-Daniel
Resource map and a way to use the pci config stuff from stage 1, done in 
a way that will work in stage 2 (but only for systems that use type 1
config cycles; will fail for type MEM config cycles). 

We need to rethink the PCI config stuff per Stepan's comment, in part 
because the device tree now includes things that are NOT PCI devices. 
Stepan's suggestion, to make the functions take busdevfn as the 
parameter, makes a lot of sense.

41242a63c3 v3: k8/m57sli wip1
This is not nearly complete, but just the current state of my tree.

k8/raminit.c does not compile at all. Lots of fixes are still needed to bring
it working into v3. I've gone through about 1/8 of the file, it errors out on
line 576 now.

The mcp55 files are in a very early state and also do not compile for me, so
I've disabled them by commenting out the select in mainboard/gigabyte/Kconfig.

Once northbridge/amd/k8/raminit.c builds, k8_ops needs to be added, then we
may actually see the first v3 k8 build. :)
