In principle this is OK, but why do you invent yet another new CONFIG_
variable (and without documenting it) ?

We have a number of boards that already use a similar construct with
CONFIG_MACH_TYPE, so I suggest you do the same.

And while being there, could you please also add a description for
CONFIG_MACH_TYPE to the README?   Thanks!

Best regards,

Wolfgang Denk
