   4 Subject: [PATCH 42/44] MIPS: BCM63XX: allow building support for more than one
   5  board type
   6
   7 Use the arguments passed to the kernel to detect being booted with
   8 CFE as the indicator for bcm963xx board support, allowing the
   9 non presence of CFE_EPTSEAL to assume a different board type.
