The base port numbers and addresses for the Geode devices are established by MSR registers, as follows:
I/O ports:
18b0 SMBUS
1000 GPIO
1800 MFGPT
1880 IRQ mapper
1400 PM
1841 ACPI
1480 AC-97
- Audio Codec: Explanations are in Datasheet Page 9
Memory space:
fd000000 Frame buffer
fe000000 Graphics processor
fe004000 Video processor
fe008000 Display controller

fe00c000 CaFe NAND
fe010000 CaFe SD
fe014000 CaFe Camera
These addresses can be "discovered" by doing PCI configuration reads to PCI device base address registers or by browing the Open Firmware device tree. link title
