Hmm yeah thanks for digging into this mystery. Looks like we're
hitting some Linux initdata limitation.

We can't mark everything as __initconst. Some platform data can
get dynamically set based on the board type for resources.

So to me it sounds like the only solution is to mark everything
as __initdata and ignore the (correct) const for now for __initdata.

Or am I missing something?

Regards,

Tony
