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.
