+Subject: [PATCH] MIPS: BCM63xx: improve CFE version detection
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+There are some CFE variants that start with 'cfe-vd' instead of 'cfe-v', such
+as the one used in the Huawei HG556a: "cfe-vd081.5003". In this case, the CFE
+version is stored as is (string vs number bytes).
+
+Some newer devices have an additional version number, such as the Comtrend
+VR-3032u: "1.0.38-112.118-11".
+
+Finally, print the string as is if the version doesn't start with "cfe-v" or
+"cfe-vd", but starts with "cfe-".
