Not all machines use this and it will only be required if CONFIG_DEBUG_LL is enabled. But when compiling for a target that uses it and it is configured for no-MMU (!CONFIG_MMU), for example the versatile machine, you will get: CC arch/arm/mach-versatile/versatile_dt.o arch/arm/mach-versatile/versatile_dt.c: In function ‘versatile_map_io’: arch/arm/mach-versatile/versatile_dt.c:283:2: error: implicit declaration of function ‘debug_ll_io_init’ [-Werror=implicit-function-declaration] debug_ll_io_init(); ^ Fix by adding a macro for it to the !CONFIG_MMU path in map.h.
