1) Fix a bug on missing hub context evaluation operation.
2) If the usb keyboard device configuration has been set successfully, then don’t set configuration again.

1) XHCI host controller hw always provides more than 5 interrupters.
Now using interrupter 0 to accommodate all received events.
2) XHCI host controller hw always provides 32bytes context size.
Now it dynamically detect context size and construct it.
also solved several issues:
1) Divides 64byte width register access to two 32bit registers access because some XHCI chipsets cannot support a single 64bit access.
2) Remove halt host controller statement in UsbBusDriverBindingStop(). It has been done by host controller’s DriverBindingStop(). And XhciDriverBindingStop() need XHCI host controller is in running state because it need execute DISABLE_SLOT cmd to release h/w resource.

1. Fix the incorrect definition of EFI_PCI_IO_ATTRIBUTE_VGA_IO_16 (does not conform to the UEFI spec) in PciIo.h.
2. Add missing definitions of ISA and VGA IO attributes in PCI Root Bridge IO protocol.
3. Improve the algorithm in the PCI bus driver to get PCI platform policy from PCI Platform Protocol and PCI Override Protocol.
4. Update the PCI bus driver to use the PCI platform policy to determine the supported attributes that are returned by the EFI_PCI_IO_PROTOCOL.Attributes() function. This is required by the PI spec.
5. Add a backward compatibility workaround for PCI VGA drivers in Option ROM, which typically sets VGA_IO without checking supported attributes.
6. Update the PCI host bridge driver in PcAtChipsetPkg to report VGA_IO_16 and ISA_IO_16 instead of VGA_IO/ISA_IO attributes. Modern chipsets don’t have hardware capability to control 10-bit or 16-bit decoding for ISA/VGA aliases.
7. Update LPC/VGA device drivers to check supported attributes of VGA_IO/VGA_IO_16 or ISA_IO/ISA_IO_16.

This check-in fix the issue by adding a flag to indicate if a HPC is found during PCI enumeration or not. This check-in also adds a debug message if any found HPC failed with initialization.

This solution defines a PCD Feature Flag to enabled support for unaligned requests through the PCI I/O Protocol. This flag is disabled by default. Platforms that do want to support such EFI/UEFI drivers that make unaligned PCI I/O requests should enable this feature.

But current PCI bus driver has a bug that if a P2P bridge has no child devices detected during enumeration, the bits won’t be set. This may impact PCI hot plug capable bridges because the OS may re-assign resources for them causing the reserved resource by the firmware will be overwritten.

These comparisons were not comparing an enum variable

GCC 4.5 generated a warning for these comparison

1. Expand the type of Offset in the _PCI_BAR structure from UINT8 to UINT16, because a VF BAR’s offset may be >= 0x100;
2. Enable ARI Capable Hierarchy for SR-IOV devices at earlier time because FirstVFOffset and VFStride of a SR-IOV device may change after its ARI Capable Hierarchy is set;
3. Change type of PcdSrIovSupport, PcdAriSupport, PcdMrIovSupport from FeatureFlag to [FixAtBuild, PcdDynamics], which allows SR-IOV/MR-IOV/ARI feature can be turn on/off dynamically, typically via a setup option.
4. Change PCI bus scan algorithm in PciScanBus() to prevent the case where some ARI extended functions may be skipped in the scan loop.

A linked list is created for the list of PCI Root Bridges in the platform. This list is then traversed to enumerate each PCI Root Bridge. After enumeration, the RootBridgeDev is destroyed, but it was not removed from the linked list before it was destroyed. This left the linked list of PCI Root Bridges in a bad state, specially if memory is cleared on frees, or the freed buffer was reallocated.
The fix is to remove the node from the linked list before the RootBridgeDev is destroyed.
