REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3171
Create the TigerlakeSiliconPkg to provide an initial package for
silicon initialization code for Tiger Lake (TGL) products.
* Major areas of functionality are categorized into CPU, IpBlock, Fru,
Platform Controller Hub (PCH), and System Agent subdirectories.
* Common libraries and headers are kept at the root of the package.

+ <b>SPI Runtime SMM Module Entry Point</b>\n
+ - <b>Introduction</b>\n
+ The SPI SMM module provide a standard way for other modules to use the PCH SPI Interface in SMM.
+
+ - @pre
+ - EFI_SMM_BASE2_PROTOCOL
+ - Documented in System Management Mode Core Interface Specification .
+
+ - @result
+ The SPI SMM driver produces @link _PCH_SPI_PROTOCOL PCH_SPI_PROTOCOL @endlink with GUID
+ gPchSmmSpiProtocolGuid which is different from SPI RUNTIME driver.
+
+ - <b>Integration Check List</b>\n
+ - This driver supports Descriptor Mode only.
+ - This driver supports Hardware Sequence only.
+ - When using SMM SPI Protocol to perform flash access in an SMI handler,
+ and the SMI occurrence is asynchronous to normal mode code execution,
+ proper synchronization mechanism must be applied, e.g. disable SMI before
+ the normal mode SendSpiCmd() starts and re-enable SMI after
+ the normal mode SendSpiCmd() completes.
+ @note The implementation of SendSpiCmd() uses GBL_SMI_EN in
+ SMI_EN register (ABase + 30h) to disable and enable SMIs. But this may
+ not be effective as platform may well set the SMI_LOCK bit (i.e., PMC PCI Offset A0h [4]).
+ So the synchronization at caller level is likely needed.
+
+ @param[in] ImageHandle Image handle of this driver.
+ @param[in] SystemTable Global system service table.
+
+ @retval EFI_SUCCESS Initialization complete.
+ @exception EFI_UNSUPPORTED The chipset is unsupported by this driver.
+ @retval EFI_OUT_OF_RESOURCES Do not have enough resources to initialize the driver.

+ <b>PchInit DXE Module Entry Point</b>\n
+ - <b>Introduction</b>\n
+ The PchInit module is a DXE driver that initializes the Intel Platform Controller Hub
+ following the PCH BIOS specification and EDS requirements and recommendations. It consumes
+ the PCH_POLICY_HOB SI_POLICY_HOB for expected configurations per policy.
+ This is the standard EFI driver point that detects whether there is an supported PCH in
+ the system and if so, initializes the chipset.
+
+ - <b>Details</b>\n
+ This module is required for initializing the Intel Platform Controller Hub to
+ follow the PCH BIOS specification and EDS.
+ This includes some initialization sequences, enabling and disabling PCH devices,
+ configuring clock gating, RST PCIe Storage Remapping, SATA controller, ASPM of PCIE devices. Right before end of DXE,
+ it's responsible to lock down registers for security requirement.
+
+ - @pre
+ - PCH PCR base address configured
+ - EFI_PCI_HOST_BRIDGE_RESOURCE_ALLOCATION_PROTOCOL
+ - This is to ensure that PCI MMIO and IO resource has been prepared and available for this driver to allocate.
+
+ - @result
+ - Publishes the @link _PCH_INFO_PROTOCOL PCH_INFO_PROTOCOL @endlink
+ - Publishes the @link _PCH_EMMC_TUNING_PROTOCOL PCH_EMMC_TUNING_PROTOCOL @endlink
+
+ - <b>References</b>\n
+ - @link _PCH_POLICY PCH_POLICY_HOB @endlink.
+ - @link _SI_POLICY_STRUCT SI_POLICY_HOB @endlink.
+
+ - <b>Integration Checklists</b>\n
+ - Verify prerequisites are met. Porting Recommendations.
+ - No modification of this module should be necessary

+ The PchInitSmm module is a SMM driver that initializes the Intel Platform Controller Hub
+ SMM requirements and services. It consumes the PCH_POLICY_HOB and SI_POLICY_HOB for expected
+ configurations per policy.
+
+ - <b>Details</b>\n
+ This module provides SMI handlers to services PCIE HotPlug SMI, LinkActive SMI, and LinkEq SMI.
+ And also provides port 0x61 emulation support, registers BIOS WP handler to process BIOSWP status,
+ and registers SPI Async SMI handler to handler SPI Async SMI.
+ This module also registers Sx SMI callback function to detail with GPIO Sx Isolation and LAN requirement.
+
+ - @pre
+ - PCH PCR base address configured
+ - EFI_PCI_HOST_BRIDGE_RESOURCE_ALLOCATION_PROTOCOL
+ - This is to ensure that PCI MMIO and IO resource has been prepared and available for this driver to allocate.

+ <b>PchSmiDispatcher SMM Module Entry Point</b>\n
+ - <b>Introduction</b>\n
+ The PchSmiDispatcher module is an SMM driver which provides SMI handler registration
+ services for PCH generated SMIs.
+
+ - <b>Details</b>\n
+ This module provides SMI handler registration servicies for PCH SMIs.
+ NOTE: All the register/unregister functions will be locked after SMM ready to boot signal event.
+ Please make sure no handler is installed after that.
+
+ - @pre
+ - EFI_SMM_BASE2_PROTOCOL
+ - Documented in the System Management Mode Core Interface Specification
+ - EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL
+ - Documented in the UEFI 2.0 Specification and above
+ - EFI_PCI_HOST_BRIDGE_RESOURCE_ALLOCATION_PROTOCOL
+ - This is to ensure that PCI MMIO and IO resource has been prepared and available for this driver to allocate.
+ - EFI_SMM_CPU_PROTOCOL
+
+ - @result
+ The PchSmiDispatcher driver produces:
+ - EFI_SMM_USB_DISPATCH2_PROTOCOL
+ - EFI_SMM_SX_DISPATCH2_PROTOCOL
+ - EFI_SMM_SW_DISPATCH2_PROTOCOL
+ - EFI_SMM_GPI_DISPATCH2_PROTOCOL

+ <b>System Agent Initialization DXE Driver Entry Point</b>
+ - <b>Introduction</b> \n
+ Based on the information/data in SA_POLICY_PROTOCOL, this module performs further SA initialization in DXE phase,
+ e.g. internal devices enable/disable, SSVID/SID programming, graphic power-management, VT-d, IGD OpRegion initialization.
+ From the perspective of a PCI Express hierarchy, the Broadwell System Agent and PCH together appear as a Root Complex with root ports the number of which depends on how the 8 PCH ports and 4 System Agent PCIe ports are configured [4x1, 2x8, 1x16].
+ There is an internal link (DMI or OPI) that connects the System Agent to the PCH component. This driver includes initialization of SA DMI, PCI Express, SA & PCH Root Complex Topology.
+ For iGFX, this module implements the initialization of the Graphics Technology Power Management from the Broadwell System Agent BIOS Specification and the initialization of the IGD OpRegion/Software SCI - BIOS Specification.
+ The ASL files that go along with the driver define the IGD OpRegion mailboxes in ACPI space and implement the software SCI interrupt mechanism.
+ The IGD OpRegion/Software SCI code serves as a communication interface between system BIOS, ASL, and Intel graphics driver including making a block of customizable data (VBT) from the Intel video BIOS available.
+ Reference Code for the SCI service functions "Get BIOS Data" and "System BIOS Callback" can be found in the ASL files, those functions can be platform specific, the sample provided in the reference code are implemented for Intel CRB.
+ This module implements the VT-d functionality described in the Broadwell System Agent BIOS Specification.
+ This module publishes the LegacyRegion protocol to control the read and write accesses to the Legacy BIOS ranges.
+ E000 and F000 segments are the legacy BIOS ranges and contain pointers to the ACPI regions, SMBIOS tables and so on. This is a private protocol used by Intel Framework.
+ This module registers CallBack function that performs SA security registers lockdown at end of post as required from Broadwell Bios Spec.
+ In addition, this module publishes the SaInfo Protocol with information such as current System Agent reference code version#.

+ - @result
+ IGD power-management functionality is initialized; VT-d is initialized (meanwhile, the DMAR table is updated); IGD OpRegion is initialized - IGD_OPREGION_PROTOCOL installed, IGD OpRegion allocated and mailboxes initialized, chipset initialized and ready to generate Software SCI for Internal graphics events. Publishes the SA_INFO_PROTOCOL with current SA reference code version #. Publishes the EFI_LEGACY_REGION_PROTOCOL documented in the Compatibility Support Module Specification, version 0.9, available at the URL: http://www.intel.com/technology/framework/spec.htm

Subject: [Patch V2 01/40] TigerlakeSiliconPkg: Add package and Include/ConfigBlock headers
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3171
Create the TigerlakeSiliconPkg to provide an initial package for
silicon initialization code for Tiger Lake (TGL) products.
* Major areas of functionality are categorized into CPU, IpBlock, Fru,
Platform Controller Hub (PCH), and System Agent subdirectories.
* Common libraries and headers are kept at the root of the package.
