From 0daf361ea799fba0af5a232036d0f06cea85ad24 Mon Sep 17 00:00:00 2001
From: Jonas Gorski <jogo@openwrt.org>
Date: Sat, 21 Jun 2014 12:47:49 +0200
Subject: [PATCH 42/44] MIPS: BCM63XX: allow building support for more than one
board type
Use the arguments passed to the kernel to detect being booted with
CFE as the indicator for bcm963xx board support, allowing the
non presence of CFE_EPTSEAL to assume a different board type.
Signed-off-by: Jonas Gorski <jogo@openwrt.org>
