coreboot-v3/device/device_util.c
coreboot-v3/device/pci_device.c
coreboot-v3/device/pci_rom.c
coreboot-v3/include/device/device.h
coreboot-v3/northbridge/amd/geodelx/dts
coreboot-v3/southbridge/amd/cs5536/cs5536.c

coreboot-v3/util/x86emu/vm86.c
Log:
include/device/device.h
Remove old vendor,device struct members since we are now using the
device_id struct.
Change declaration of dev_find_device to use device_id struct.
device/device_util.c
Change dev_find_device to use device_id struct instead of vendor, device
parameters.
Add convenience function, dev_find_pci_device, to make it easier for
users.
device/pci_device.c
Change uses of dev->vendor and dev->device to dev->id.
Change prints of dev->vendor, dev->device to use the
dev_id_string function.
device/pci_rom.c
Change uses of dev->vendor and dev->device to dev->id.
southbridge/amd/cs5536/cs5536.c
Change uses of dev_find_device to dev_find_pci_device
southbridge/amd/cs5536/dts
Add pciid of the cs5536
northbridge/amd/geodelx/dts
add pciid of the geodelx northbridge.
util/x86emu/vm86.c
Change uses of dev_find_device to dev_find_pci_device
With these changes, the chipsetinit function now finds the southbridge
in the static tree, which is the first time this has worked in v3.
This success in turn means that the chipsetinit code is running for the
first time.
We are still failing in "Finding PCI configuration type"
