-/* Various workarounds for chipset bugs.
-   This code runs very early and can't use the regular PCI subsystem
-   The entries are keyed to PCI bridges which usually identify chipsets
-   uniquely.
-   This is only for whole classes of chipsets with specific problems which
-   need early invasive action (e.g. before the timers are initialized).
-   Most PCI device specific workarounds can be done later and should be
-   in standard PCI quirks
-   Mainboard specific bugs should be handled by DMI entries.
-   CPU specific bugs in setup.c */
