| * Note about PCI IO space mappings |
| * To make IO space accesses efficient, we store virtual addresses in |
| * The PCI IO space is located at virtual 0xfe000000 from physical |
| * 0x90000000. The PCI BARs must be programmed with physical addresses, |
| * but when we read them, we convert them to virtual addresses. See |
| * arch/arm/mach-iop3xx/iop3xx-pci.c |
| #define pcibios_assign_all_busses() 1 |
| * The min PCI I/O and MEM space are dependent on what specific |
| * chipset/platform we are running on, so instead of hardcoding with |
| * #ifdefs, we just fill these in the platform level PCI init code. |
