The following series of patches adds TPM (Trusted Platform Module) support to Qemu. An emulator for the TIS (TPM Interface Spec) interface is added that provides the basis for accessing a 'backend' implementing the actual TPM functionality. The TIS emulator serves as a 'frontend' enabling for examp
