    Subject[PATCH v3 05/17] frv: io: implement dummy relaxed accessor macros for writes
    Date
    write{b,w,l}_relaxed are implemented by some architectures in order to
    permit memory-mapped I/O accesses with weaker barrier semantics than the
    non-relaxed variants.

    This patch adds dummy macros for the write accessors to frv, in the same
    vein as the dummy definitions for the relaxed read accessors.
