io_block_mapping() isn't really an interface I would recomment for
anybody to use... What about __ioremap() instead ?

I also notice that Marvell didn't both submitting any patch for
supporting their board, I suppose they are happy with just providing
customers with their hacks and no attempt to have them validated &
merged upstream ...
