- * Handle resources of PCI devices. If the world were perfect, we could
- * just allocate all the resource regions and do nothing more. It isn't.
- * On the other hand, we cannot just re-allocate all devices, as it would
- * require us to know lots of host bridge internals. So we attempt to
- * keep as much of the original configuration as possible, but tweak it
- * when it's found to be wrong.
- *
- * Known BIOS problems we have to work around:
- * - I/O or memory regions not configured
- * - regions configured, but not enabled in the command register
- * - bogus I/O addresses above 64K used
- * - expansion ROMs left enabled (this may sound harmless, but given
- * the fact the PCI specs explicitly allow address decoders to be
- * shared between expansion ROMs and other resource regions, it's
- * at least dangerous)
- *
- * Our solution:
- * (1) Allocate resources for all buses behind PCI-to-PCI bridges.
- * This gives us fixed barriers on where we can allocate.
- * (2) Allocate resources for all enabled devices. If there is
- * a collision, just mark the resource as unallocated. Also
- * disable expansion ROMs during this step.
- * (3) Try to allocate resources for disabled devices. If the
- * resources were assigned correctly, everything goes well,
- * if they weren't, they won't disturb allocation of other
- * resources.
- * (4) Assign new addresses to resources which were either
- * not configured at all or misconfigured. If explicitly
- * requested by the user, configure expansion ROM address
- * as well.
