If the pins need to be configured for the system to boot that needs
to be in the big kernel image anyway. And then it should be bool.

Example: to mount the root filesystem on external flash pin
configuration needs to happen.

There is a slight paradigm shift sometimes: in distribution
kernels it might be required that necessary modules are
included in an initramfs attached to the kernel. I do not know
if we want to encourage that type of configuration for embedded
ARM.
