-          The AV7110 firmware is normally loaded by the firmware hotplug manager.
-          If you want to compile the firmware into the driver you need to say
-          Y here and provide the correct path of the firmware. You need this
-          option if you want to compile the whole driver statically into the
-          kernel.
+          Alternatively, you can download the file and use the kernel's
+          EXTRA_FIRMWARE configuration option to build it into your
+          kernel image by adding the filename to the EXTRA_FIRMWARE
+          configuration option string.
