+Subject: [PATCH] MIPS: BCM63XX: handle huawei nvram layout
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Huawei uses a custom nvram layout, extending it with additional 32
+byte field. This pushes also the checksum further, causing it to
+always fail the check.
+
+Add an additional crc check for handling this modified nvram layout
+based on the different size.
