for LPC32xx platform I sent a general savedefconfig update, which
automatically removes all unused build options:
http://www.spinics.net/lists/arm-kernel/msg497889.html

Probably you may do something similar for S3C24xx and send the change
to Samsung maintainers.

I'd prefer not to do it mechanically, please check the things that
changed to see if they made sense.

The option is gone, that is fine.

This one moved around, better not mix that with the other changes.

Two boards select this, and are apparently enabled by default.
Why? Could we remove the 'select' and leave this line?

Why remove this? Is TPS65010 disabled now? Maybe its dependencies
need to be updated.

This was removed in v3.11, but a lot of defconfigs still
try to enable it. Maybe do them all at once?

Same thing, removed in v4.6, but still referenced in 199 files.

I'm hardly the guy to be in the position to verify ARM config stuff.
Actually, my original intention was much simpler:

https://lkml.kernel.org/r/1459338168-29334-2-git-send-email-bp at alien8.de

but then Vladimir suggested I should do the savedefconfig thing.

That patch looks good, sorry I missed it. I see that Vladimir already
did the lpc32xx portion of it, can you send the part for s3c24xx
to the exynos maintainers?

If you have larger chunks like CONFIG_INET_LRO removal, we can take
that directly through arm-soc as a single patch for all defconfigs.

I'll leave that to someone who wants to get their feet wet with patching
the kernel - should be a simple task. :-)
