+       help
+         This enables support for TPMs which can be used to provide security
+         features for your board. The TPM can be connected via LPC or I2C
+         and a sandbox TPM is provided for testing purposes. Use the 'tpm'
+         command to interactive the TPM. Driver model support is provided
+         for the low-level TPM interface, but only one TPM is supported at
+         a time by the TPM library.
