Sure, but it's not my call what the i.MX guys do. I'm just generalizing
what i.MX already has for other platforms to use. Since we have no way
to create static mappings from devicetrees I don't think we want to
expand static mappings. Also, your past guidance has been to get rid of
static mappings.

Even if we got rid of it here and on msm, there are still other
platforms that need custom ioremap where static mappings won't help.
ebsa110 and ixp4xx also need ioremap but I didn't convert them to
runtime from compile time since they still need io.h for other reasons
at this point.
