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.
