| 433 | This is the memory-mapped address of PCI configuration space, which |
| 434 | is only available through the Enhanced Configuration Access |
| 435 | Mechanism (ECAM) with PCI Express. It can be set up almost |
| 436 | anywhere. Before it is set up, it is possible to access PCI |
| 437 | configuration space through I/O access, but memory access is more |
| 438 | convenient. Using this, PCI can be scanned and configured. This |
| 439 | should be set to a region that does not conflict with memory |
| 440 | assigned to PCI devices - i.e. the memory and prefetch regions, as |
| 441 | passed to pci_set_region(). |
