f2872767a2 Add AP detection to stage0 to prevent APs from re-initializing mainboard setup
that has already been done by the BSP. For single processor systems the CPU
flag is always 0, BSP. This code also moves the AP stop for K8 mainboards to
after memory setup so the AP's MTRRs can be setup to match system memory.

cb5d9d3867 cs5536: Remove redundant enable_ide variable from ide device.
The device infrastructure already has an enabled bit, so we don't need to duplicate it in the current form.
cs5536.c:ide_init() is phase6_init, which is called only if the device is enabled, so if the device doesn't
exist, or the mainboard dts says "disabled;" for it, the init is not done and an extra conditional is not
necessary.
Adapt all cs5536 using mainboards to it (removing enable_ide variable) - artecgroup/dbe6[12] gets the whole
IDE device removed, which results in the ide_init() code not being ran as before (before it was called but
early return from enable_ide == 0, now it won't be called in the first place).

33e15e4148 This is a small HT fixup until HT links get figured out better.
It removes processors from the list of devices on the domain's bus so
that pci_scan_bus won't disable them, then scans for them, then puts
them back.  There are lots of other ways to do this, but this one
seemed minimally invasive and ends up with a correct tree.

The dts fixups I should have put in with the other K8 patch for the
new resource allocator.  I went to the v2 Config.lb files and tried to
get them as complete as possible.

13765fd116 This patch updates geodelx to fit the new resource allocator better. It
splits the domain and the memory controller functions into their respective
devices.

It also updates the dts for all the boards that use geodelx_video_mb.

bdc76a22a0 This patch fixes up k8 for the new resource allocator. It splits
northbridge functions and makes devices children of the northbridge.
	
northbridge/amd/k8/domain.c: 
	Add the functions from k8/pci.c that belong to the domain.  Add
support for physical link numbers in resource indices.  Combine find_iopair
and find_mempair to find_regpair.

northbridge/amd/k8/pci.c:
	Remove functions that went to the domain.

device/hypertransport.c:
	Add support for HT connections from devices that aren't the bus
controller.

device/hypertransport.h:
	Change the prototype of hypertransport_scan_chain.

northbridge/amd/k8/pci:
	Take out bridge flag.

mainboard/amd/serengeti/stage1.c
	Change first register usage.

12a3094274 This patch makes subsystem ids work. Here are the changes by file:
device/pci_device.c:
    Only update IDs if:
    - The device is on the mainboard
    - The device has a Vendor ID and Device ID
    - The device has a set_subsystem function in ops_pci(dev)

util/dtc/flattree.c:
    Make devices from the dts be on_mainboard.
    If they're plugged in, they shouldn't be in the dts.

mainboard/amd/serengeti/dts:
    Add subsystem_vendor and subsystem_device.

Build tested on Serengeti.  Getting closer :)

81b79f9052 This patch cleans up the showallroutes utility:
1. fix if->in in comments
2. change width of output for different types
3. make all masks 0x so that it's easy to tell a mask

It also changes the invocations to do function 1 instead of 0.

I think we should consider a name that makes it clear that this is only good
for AMD K8+ processors function 1.  We might need a similar utility for other
functions later.

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.

28ecbeab88 The K8 is one example, but there are other devices (e.g. I2C) that also have
multiple links. The way this was done in v2 was a big confusing; this way is 
less so. 

The changes are easy. Getting them right has been hard :-)

First, for a k8 north that has three links, you can name each one as follows:
pci0@18,0
pci1@18,0
pci2@18,0

We have to have the same pcidevfn on these because that is how the k8 works. 
But the unit numbers (pci0, pci1, etc.) distinguish them. 

The dts will properly generate a "v3 device code" 
compatible static tree that puts the links in the right place in the 
data structure. 

The changes to dts are trivial. 
As before, dts nodes with children are understood to be a bridge. 
But what if there is a dts entry like this:
pci1@18,0 {/config/("northbridge/amd/k8/pci");};


This entry has no children in the dts. 
How does dt compiler know it is a bridge? It can not know unless 
we add information to the dts for that northbridge part. 
To ensure that all bridge devices are detected, we support the following: 
if a dts node for a device has a bridge property, e.g.: 
 {
        device_operations = "k8_ops";
       bridge;
 };

The dt compiler will treat it as a bridge whether it has children or not. 

Why would a device not have children? Because it might be attached to a
pci or other socket, and we don't know at build time if the socket is empty, 
or what might be in the socket. 

This code has been tested on dbe62 and k8 simnow, and works on each. 
It is minimal in size and it does what we need. I hope it resolves our 
discussion for now. We might want to improve or change the device code
later but, at this point, forward motion is important -- I'm on a deadline for
a very important demo Oct. 22!

Also included in this patch are new debug prints in k8 north.

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
are welcome.

fd31dee2a6 Closer to compiling. Add the fidvid functions. Continue to remove romcc
legacy. Use constants as much as possible instead of magic numbers. Set 
up common prototypes in an include file. 

The fidvid needs major cleanup but this code is so tricky I don't want 
to start cleanup until I feel it is more or less working.

6fd7abea43 Off to bed. I'm done for now.
If anyone wants to review my comments, or maybe even try to fix compile 
issues, have at it :-)

The more I work with the K8 stuff the more impressed I am with the 
people who got it all to go 6 years ago. (and at how much I've forgotten 
but that's another story :=)

If we can get this next step done we're very close to having a working 
initram. 

And, once you have ram and hit stage2, life is just better all around.

b0144f19c7 This code is not in a working state but I want to get it into the repo
since the box it is on is kinda old. 

I realize it is wrong but it is getting there. 

The k8 startup is a work of genius. I hope at some point it will be a 
work of genius that the rest of us can understand :-)

But it's very impressive code in how it works.

3e9b43f32f BIST handling. Unless I'm mistaken, we already die() in stage1_main() if
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.

27b2fb4f07 Every GeodeLX target already has spd_read_byte in
mainboard/$VENDOR/$BOARD/initram.c. It's pointless to have it in the
southbridge code as well.
Kill it in the southbridge code and use mainboard code only.

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.

df78385663 1. Add call to stage 1 ht setup for mainboard
2. add support for same, brought over from v2.

Still no luck on 8111 ISA however. What are we missing?
The symptom is simple: Device 0:b.0 does not appear in the PCI list, so 
device with vid/did 1022/7468 is not there, so we can not enable 5 MiB 
flash addressing.
