I guess that is board-specific and shouldn't be modified by a user.
How about this:

>  config MIPS_CM_BASE
>         hex
>         depends on MIPS_CM
>         default 0x16100000 if TARGET_BOSTON

>         help
>           The physical base address at which to map the MIPS Coherence Manager

Then you don't have to add this option to your board's defconfig
files. This would also help if we want to support builds with "make
randconfig" in the future.
