+ *
+ * 2.	MicroSoft Authentication Code (mscode)
+ *	MbedTLS only supports Content Data type defined as 1.2.840.113549.1.7.1
+ *	(MBEDTLS_OID_PKCS7_DATA, aka OID_data).
+ *	1.3.6.1.4.1.311.2.1.4 (MicroSoft Authentication Code, aka
+ *	OID_msIndirectData) is not supported.
+ *	See MbedTLS function 'pkcs7_get_content_info_type' for details.
+ *
+ * But the EFI loader assumes that a PKCS#7 message with an EFI image always
+ * contains MicroSoft Authentication Code as Content Data (msg->data is NOT
+ * NULL), see function 'efi_signature_verify'.
+ *
+ * MbedTLS patch "0002-support-MicroSoft-authentication-code-in-PKCS7-lib.patch"
+ * is to support both above features by parsing the Content Data and
+ * Authenticate Attributes from a given PKCS#7 message.
+ *
+ * Other fields we don't need to populate from MbedTLS, which are used
+ * internally by pkcs7_verify:
+ * 'signer', 'unsupported_crypto', 'blacklisted'
+ * 'sig->digest' is used internally by pkcs7_digest to calculate the hash of
