+- rule: Force older TPM compatibility combined failure as ignored
+    The ACS SCT test is verifying compatibility with TPM capabilities 1.0.
+    U-Boot up to at least version 2023.10 does not support TPM capabilities 1.0
+    and also erroneously returns BUFFER_TOO_SMALL in this case instead of
+    SUCCESS.
+    BBSR does not mandate compatibility with older TPM capabilities 1.0;
+    it only requires TCG2, TPM capabilities 1.1.

+    descr: Testing For EFI TCG2 Protocol
