This patch provides a stub function for mvebu_mbus_get_io_win_info(),

Hi Stefan

If i understand it correctly, this should never be used for real, it
is here only for compile testing?

Correct.

Maybe add a WARN_ON_ONCE(1) here? And a comment, why it should never
happen.

Yes, I could do this. I (as others too) just followed this example here:

git ID 63a9332b "ARM: Orion: Get address map from plat-orion instead
of via platform_data"

Should I add these WARN_ON_ONCE(1) macros to the other stub functions
in this header as well? Perhaps as a new 3rd patch in this series?

Thanks,
Stefan
