+ * Ideally, we want to directly include it without having two maintain
+ * duplicate copies in sync. But in the current model, this is hard
+ * to do without breaking standalone compilation.
+ * Eventually tpm_lite should be moved into vboot_reference.
+ *
+ * FURTHER NOTE: The subset of TPM error codes relevant to verified boot
+ * (TPM_SUCCESS, etc.) are in tss_constants.h.  A full list of TPM error codes
+ * are in /usr/include/tss/tpm_error.h, from the trousers package.
