10 * Note about PCI IO space mappings
12 * To make IO space accesses efficient, we store virtual addresses in
15 * The PCI IO space is located at virtual 0xfe000000 from physical
16 * 0x90000000. The PCI BARs must be programmed with physical addresses,
17 * but when we read them, we convert them to virtual addresses. See

25 * The min PCI I/O and MEM space are dependent on what specific
26 * chipset/platform we are running on, so instead of hardcoding with
27 * #ifdefs, we just fill these in the platform level PCI init code.
