rsun3 4ed4e19c08 Update the PCI bus driver to correctly set the EFI_PCI_IO_ATTRIBUTE_EMBEDDED_ROM attribute of PCI IO. Per UEFI spec, this attribute is used to determine if the ROM image is from the ROM BAR or from a platform specific location.

rsun3 55565b0859 The PCI HotPlug Init Protocol returns a list of Root HPC, but it is possible that some HPCs in the list are not found during PCI enumeration. In this case, the PCI HotPlug Init Protocol.InitializeRootHpc() will not be called for the un-found HPCs. However, in AllRootHPCInitialized(), all reported HPCs are checked to see if it has been initialized, so TIME_OUT happens. 
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.

rsun3 aeeb84bab4 Some existing PCI adapters with UEFI option ROMs make unaligned requests through the PCI I/O Protocol. Add support for unaligned requests in the PCI IO protocol implementation in the PCI Bus driver to be compatible with those UEFI option ROMs. 
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.

rsun3 13fd0d50b5 Per the UEFI spec, if a PCI controller is a P2P bridge, then the I/O, Memory and Bus Master bits in the Command register of the PCI configuration header should be placed in the enabled state by the PCI Bus driver. 
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.

rsun3 d40483911c Fix bugs in the PCI bus driver to support SR-IOV. 
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.

mdkinney 8063b47b1c Fix bug in PciHostBridgeEnumerator(). 
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.

erictian e172ea16a7 roll back the parameter check of AsyncInterruptTransfer() and SyncInterruptTransfer() of Usb2HcProtocol to follow current uefi spec. 
current uefi spec only supports interrupt in endpoint.
but there are usb devices which support interrupt out endpoint. we propose to update uefi spec to remove the limitation. after the ecr is approved, the corresponding patch will be submitted.
