Add a display string and a help section to the config AUXILIARY_BUS
section under the "Generic Driver Options" menu in order to make its
selection clearer.

That's the point of how it currently is though, no?
We don't allow users to set the option, but rather any device driver
that needs it, selects it.
That way, a person configuring their kernel for some hardware just needs
to enable the drivers for their hardware and knowledge of kernel
internals is not needed.
Is there a particular driver, perhaps in drivers/accel, that does not
select the option, which is why you are trying to set it yourself?
Cheers,
Conor.

No, nothing specific. Just saw it and thought it is an issue to address,
sent a private mail to the author (Dave Ertman <[email protected]>)
Who replied that he was unaware that it was a naked bool in the base/Kconfig file!
And there is no reason that he is aware of for it to be that way.
So, I've added it.

The reason is that as Conor says, it is not a user-selectable option, it
comes in by virtue of a driver that requires it enabling it, that's all.
