REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3966

This patch series is a follow up of previous submission:
https://edk2.groups.io/g/devel/message/91075

v2 patch changes include feedback for v1 series:
a. Removed PCD replacement related code change;

>From PI Specification v1.7 Errata A, EFI_PERIPHERAL_DOCKING is defined as
0xD0000 (as well as included in PiStatusCode.h).

However, subclass employed as PCD for TPM peripheral in SecurityPkg is
also defined as 0xD0000. The TPM subclass code was used in TcgPei.c when
reporting error codes.

The collision of subclass definition could cause the parsing of reported
errors being ambiguous.

This patch series add EFI_PERIPHERAL_TPM as a spec-defined value and
removed potential usages in the SecurityPkg.

Patch v2 branch: https://github.com/kuqin12/edk2/tree/BZ3966-add_tpm_subclass_v2

+# Title: Introduction of `EFI_PERIPHERAL_TPM` Peripheral Subclass Definition
+
+## Status: Draft
+
+## Document: UEFI Platform Initialization Specification Version 1.7 Errata A
+
+## License
+
+SPDX-License-Identifier: CC-BY-4.0
+
+## Submitter: [TianoCore Community](https://www.tianocore.org)
+
+## Summary of the change
+
+Add `EFI_PERIPHERAL_TPM` into Peripheral Subclass definition.
+
+## Benefits of the change
+
+Current status code covered various [peripheral subclass definitions](https://github.com/tianocore/edk2/blob/master/MdePkg/Include/Pi/PiStatusCode.h).
+
+As Trusted Platform Module (TPM) becomes more available on the modern systems, status reports from such peripheral are playing more important roles in anaylzing the secruity state and healthiness of a system. However, peripheral subclass definitions do not cover TPM as of today.
+
+Standardizing the TPM peripheral subclass definition could facilitate the parsing of peripheral reported errors and avoid potential definition collisions from implementation based subclass usages.
+
+The request of this change intends to expand definitions of `EFI_PERIPHERAL_**` under Periperhal Subclass definitions to cover the TPM subclass.
+
+## Impact of the change
+
+Occupy a new macro definitions of subclass under `Defined Subclasses: User-Accessible Peripheral Class`.
+
+## Detailed description of the change [normative updates]
+
+### Specification Changes
+
+1. In PI Specification v1.7 Errata A: Vol. 3, Table 3-30: Defined Subclasses: User-Accessible Peripheral Class, add one new rows below `EFI_PERIPHERAL_DOCKING` definition and adjust the rest of reserved definitions accordingly:
+
+    | Subclass | Code Name | Description |
+    | --- | --- | --- |
+    | Trusted Platform Module | EFI_PERIPHERAL_TPM | The peripheral referred to is a Trusted Platform Module |
+    | 0x0F–0x7F | Reserved for future use by this specification |  |
+
+1. In PI Specification v1.7 Errata A: Vol. 3, Table 3-84: Defined Subclasses: User-Accessible Peripheral Class, add one new rows below `EFI_PERIPHERAL_DOCKING` definition and adjust the rest of reserved definitions accordingly:
+
+    | Subclass | Code Name |
+    | --- | --- |
+    | Trusted Platform Module | EFI_PERIPHERAL_TPM |
+    | 0x0F–0x7F | Reserved for future use by this specification. |
+
+1. In PI Specification v1.7 Errata A: Vol. 3, Section 6.7.2.1 Subclass Definitions: Prototype, add one new definitions below `EFI_PERIPHERAL_DOCKING` definition:
+
+    ```c
+    #define EFI_PERIPHERAL_TPM \
+      (EFI_PERIPHERAL | 0x000E0000)
+    ```
+
+### Code Changes
+
+1. Add macro definitions in `MdePkg/Include/Pi/PiStatusCode.h` to match new specification.
+1. Updated the default value of `gEfiSecurityPkgTokenSpaceGuid.PcdStatusCodeSubClassTpmDevice` to `(EFI_PERIPHERAL | 0x000E0000)` for consistency and backwards compatibility outside of SecurityPkg.

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3966

This change introduces a new peripheral subclass definition.

The new subclass definition will cover system reboot events under the
status reports from Trusted Platform Modules (TPMs).

These definition could provide helpful datapoints to OEMs to analyze
system security state and healthiness, as well as avoid definition
collision with other existing peripheral subclass definitions.
