[OpenWrt-Devel] [PATCH] [brcm47xx] Belkin F7DXXXX (BCM47XX based) support for Linux 3.18

Patch didn't seem to mail properly, trying again.
From: Joseph East <eastyjr at gmail.com>
Patchset based on previous work by Cody Schafer and Luc Forcier to allow
TRX images with Belkin IDs to be compiled as part of the BRCM47XX
platform for Linux 3.18.
The patchset has been tested with a Belkin F7D4401 (PlayMax N600), other
devices part of the previous patch are untested but have been included,
however the Belkin QA TRX signature has been removed.
The otrx tool has been modified to accept a -m argument which allows
comparison against a user defined TRX signature, this works in tandem
with the changes in platform.sh to verify the different Belkin TRXs for
supported models.
