mn10300: io: implement dummy relaxed accessor macros for writes
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 mn10300, in the same vein as the dummy definitions for the relaxed read accessors. Cc: David Howells <> Signed-off-by: Will Deacon <>
