This is prepartion patch to add softwared-based TPM library
using TCG TPM v2.0 Reference Library[0].
TCG TPM v2.0 Reference Library[0] provides the TPM device functions
with platform specific layer. This layer has platform interfaces
which start with prefix "__plat_" to implement software based TPM.
PlatformTpmLib is used to implment these interfaces.
When TpmLib calls "__plat_XXX()", the correspond function
"PlatformTpmLibXXX()" in PlatformTpmLib would be called.
Not all __plat_XXX interfaces are required to be implemented, and
default implementations for some interfaces can be utilised.
Here, PlatformTpmLib implements correspond __plat_XXX function in
TPM reference library files:
- Clock.c
- ExtraData.c
- Failure.c
- NVMem.c
- Unique.c
- VendorInfo.c
NOTE:
To support to generation of platform specific endorsement seed,
the function PlatformTpmLibGetEPS() is defined in EPS.c
This platform function allows a platform to specify an endorsement seed
when the fTPM is manufactured.
