Description

Adding a new PCI_RES_BUS resource type and use rmans in PCI bridges to manage allocation of bus numbers.

Some machines (esp. cardbus bridges in laptops) do not assign numbers to the full tree on boot. For now the goal is only to support assigning numbers to unnumbered buses, not renumbering the entire tree.

I have fleshed this out some more and it passes simple tests. Things remaining to test:

  • Nested bridges configured by firwmare.
  • A "clear" mode where it assigns busses.
  • Set pribus?
  • The cardbus changes are untested.
