* An implementation of a keymaster::Serializable type that refers to a TPM type

* by an unmanaged pointer. When the TpmSerializable serializes or deserializes
|
|
* data, it loads it from and saves it to the pointed at instance.
|
|
*
|
|
* The serialization format is the same as the one used in the command protocol
|
|
* for TPM messages.
|
|
*
|
|
* This is a template class, specialized in the corresponding implementation
|
|
* file for the TPM types necessary to serialize as part of larger Keymaster
|
|
* serializable types.
