Yeah sure, to define it I would put into our board config.

But what I ment here is it would be the first use of
CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG in _code_ under arch/arm. All other
uses of CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG are in board specific code
under boards/...

Ok, use it only in our config then.
