Joint patch
By sir_richard: [PCIX]: - Implement PciIsSlotPresentInParentMethod for ACPI query, and PcoDecodeEnable utility function.
- Implement PciConfigureIdeController based on WDHC Whitepaper "How Windows Switches a Controller to Native Mode". Check for PciEanbleNativeModeATA in registry, InitSafeBootMode, and call the ACPI driver to evaluate if NATA is present on the slot. Only configure the controller if both channels support native mode, as this is a Windows restriction.
- Implement PciApplyHacks for enumeration and resource update cases. In the first case, we handle legacy DEC Alpha Intel i82375 and i82378 PCI-to-(E)ISA bridges with invalid class codes. In the second, we configure IDE controllers for Native mode, except the OPTi Viper-M, which is known to cause issues. We also support cards with legacy VGA decodes by telling the arbiter to enable full access to the rangesm and finally we completely disable the decodes on Compaq PCI Hotplug Controllers (Revision 17) on PAE systems, as they have bugs handling 64-bit addresses. Finally, on resource updates, we apply a vendor-specific errata to the IBM 20H2999 PCI Docking Bridge (Hotplug) used on Thinkpad 600 Series laptops, and we attempt to avoid issues that can happen on certain devices that are plugged into an ICH1/2/3/4 Intel Hub when it has been configured to do subtractive decode. Full information on these workarounds can be seen in the comments. Finally, we also enable CardBUS devices for ACPI-compliant mode, by crossing out the LegacyBaseAddress in the CardBUS Type 2 PCI Configuration Header.
- Miscelleaneous code cleanups.
By eVb: More PciScanBus support, for debug PCI caps that driver use are dump, and detect nonBIOS configure device (spec is said that CacheLineSize != 0, LatencyTimer != 0 (on PCI-X, != 64)), if found NeedsHotPlugConfiguration to be set
By eVb: Support PCI_HACK_VIDEO_LEGACY_DECODE (call ario_ApplyBrokenVideoHack, but no arb support to do work)
