Could you explain a bit _how_ broken current's
arch/mips/lib/iomap.c ?  Is it a single mips_io_port_base issue?

I suppose it works as well as traditional way (request_region +
in[bwl] for IO resource, request_mem_region + iomap + read[bwl] for
MEM resource).

I think it is better than generic iomap.c (except that
ioremap_cacheable_cow which is not available for R3000 is used).
