to look at the new patch set (#3).

soc/amd/cezanne/acpi: Add pci0.asl
This differs slightly from picasso. The PCI BAR region is between TOM1 and CONFIG_MMCONF_BASE_ADDRESS. This matches what the Intel platforms are doing. It also matches what linux derives from the e820 tables:
[mem 0xd0000000-0xf7ffffff] available for PCI devices
Picasso currently declares the region between TOM and IO_APIC_ADDR. This region includes MMCONF. We don't want to map any PCI BARs in this region.
