* tpm: transition tpm_vtpm_proxy documentation to the SphinxJarkko Sakkinen2016-11-082-38/+24
| | | | | | | | | | | Transitioned the tpm_vtpm_proxy documentation to the Sphinx infrastructure and removed parts from the documentation that are easier to pull from the sources. Restructured vtpm_proxy.h and tpm_vtpm_proxy.c to be compatible with this approach and wrote associated documentation comments.

* drivers/tpm: add xen tpmfront interfaceDaniel De Graaf2013-08-091-0/+113
This is a complete rewrite of the Xen TPM frontend driver, taking advantage of a simplified frontend/backend interface and adding support for cancellation and timeouts. The backend for this driver is provided by a vTPM stub domain using the interface in Xen 4.3.
