Hi Mike,
The intention was to encourage the usage of new definition in .H file
once the definition
is updated. The PCD is left as is only to serve as backwards
compatibility purpose.
Do you think only updating the DEC and .H file is more ideal? I could
drop the other changes
if so desired.
Thanks,
Kun

Hi Kun,
Why was the PCD usage not preserved and only the value updated in the DEC file
and .H file?

Subject: Re: [edk2-devel] [edk2-staging][PATCH v1 0/7] Add TPM subclass
definition
Hi SecurityPkg maintainers & EDK2 stewards,
I sent out this patch series intending to update/fix the PI spec through
code first process.
Could you please shed some light on it and let me know if any feedback?
Thanks in advance!
Regards,
Kun

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