> This is defined by TPM2 ACPI table Version 1.2, Revision 8.
> It only impacts the TPM2 ACPI table version 4 or above.

> The new fields are only for TCG2 log format, but not TCG1.2 log format.

> Test:
> Use default TPM2 version 3. No ALMA/ALSA shown in TPM2 table.
> Use TPM2 version 4. The DXE driver reports ALMA/ALSA PCD and the SMM driver
> installs ALMA/ALSA in TPM2 table.
