Review Comment:
if so, we need select this config for the driver which support mmap command.
But if nobody calls mmap and munmap, the linker will remove all related code
from final image. On the other hand, the driver which implement mmap function
can't remove even nobody call mmap and munmap since it's very hard to let
compiler/linker to remove the reference by pointer.
