Yes, but there there are many drivers that only use readl/writel (and
arch/arm makes the assumption, maybe correctly, that this is little
endian only).

I think that's useful even if the outcome of such discussion is better
documentation on the above functions/macros (grepping Documentation/
doesn't show any reference).
