+	  Cr50 is an implementation of a TPM on Google's H1 security chip.
+	  This uses the same open-source firmware as the Chromium OS EC.
+	  While Cr50 has other features, its primary role is as the root of
+	  trust for a device, It operates like a TPM and can be used with
+	  verified boot. Cr50 is used on recent Chromebooks (since 2017).
