We had a jump instead of a call to stage1_main in geodelx/stage0.S. That
means all accesses to bist and init_detected were off by 8 bytes and
collided with accesses to the global variable pointer.
Found during my cleanup runs.
This bug had the following effects:
1.) If gcc had decided to reload bist from stack after initializing the
global variable pointer, bist would have been nonzero, an indicator for
processor failure.
2.) If gcc had decided to use the stack location of bist as a scratch
register (and it probably is free to do so as long as the contents are
restored before returning), it would have clobbered the global variable
pointer, leading to NULL pointer dereferences.
3.) Any accesses to init_detected would have resulted in accessing 4
bytes above the top of stack (0x87ffc-0x87fff), something the rest of
the code deliberately avoids.

There are some interesting issues here. The enables for the various
devices are a global bitmask:
Define port_enable, (bit map): GFX(2,3), GPP(4,5,6,7)
But v3 would allow us to not have the bit mask. OTOH, we would end up
with 3 .dts files for the pcie ports for this enable; good or bad?
GOOD --> highly custom configuration possible for each port
BAD --> 3 .dts files
Part of the issue is that the link from the dts to the device operations
structure is done as follows:
struct device_operations sb600_usb2 = {
.id = {.type = DEVICE_ID_PCI,
{.pci = {.vendor = PCI_VENDOR_ID_ATI,
.device = PCI_DEVICE_ID_ATI_SB600_USB2}}},
And this structure is named in the .dts for that device_operations:
{
device_operations = "sb600_usb2";
};
requiring a different dts node for each set of device_operations.
The device tree compiler generates the code to create these connections
and puts that code into the the static_tree.c file.
Having a .dts file for each port gives us a lot of flexibility; but is
it too inconvenient? This is an unresolved problem; unhandled at present
for the *6* USB ports for the sb600.

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.
