This required lots of preparatory work to not make the existing stage0
situation worse.
Thanks to Jason Zhao we got a skeleton CAR code for VIA C7 based on
older v2 code.
I cleaned it up, modified it to fit into the improved v3 stage0 code
infrastructure and believe this is mostly merge-ready.
Thanks to Bari Ari for getting the code to me for rewrite/review.
Thanks to Corey Osgood who kept me going with helpful early tests and
motivation.
Thanks to everybody who reviewed my code.

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.
