Ok, got it. In that case I don't see a better alternative to your
patch anyway, especially since IOP13xx apparently predates
CONFIG_ARCH_PHYS_ADDR_T_64BIT and implemented the ioremap hack
in order to get around the same limitation. Changing this now for
a legacy platform is something I wouldn't want to try.

Thanks,
