The NI 169445 board uses a little endian MIPS32r2 CPU, and therefore including board support in kernels that are unable to run on such a CPU is pointless. Specify requirements in the board config fragment that cause the NI 169445 board support to only be included in generic kernels that target little endian CPUs & architecture revisions prior to MIPSr6. For example, NI 169445 support will be included when configuring using 32r2el_defconfig but not when using 64r6_defconfig.
