TCG EFI Protocol Specification for TPM Family 2.0 Revision 1.0 Version 9 at http://www.trustedcomputinggroup.org/resources/tcg_efi_protocol_specification TCG Physical Presence Interface Specification Version 1.30, Revision 00.52 at http://www.trustedcomputinggroup.org/resources/tcg_physical_presence_interface_specification Add Tcg2XXX, similar file/directory as TrEEXXX. Old TrEE driver/library can be deprecated. 1) Add Tcg2Pei/Dxe/Smm driver to log event and provide services. 2) Add Dxe/Pei/SmmTcg2PhysicalPresenceLib to support TCG PP. 3) Update Tpm2 library to use TCG2 protocol instead of TrEE protocol. Test Win8/Win10 with SecureBoot enabled, PCR7 shows bound.

Define the variable data structures used for TCG2 physical presence.
|
|
The TPM2 request from firmware or OS is saved to variable. And it is
|
|
cleared after it is processed in the next boot cycle. The TPM2 response
|
|
is saved to variable.
