Re: [PATCH 1/4] SecurityPkg: enable TPM components to build for ARM and AARCH64

["Kinney, Michael D" <michael.d.kinney@intel.com>]

Jiewen,

There are I2C examples for TPM12 in the
QuarkPlatformPkg.  Would that we a good example
too?

Could this new lib class be used for both 
TPM12 and TPM20 devices?
