Interestingly, this function looks completely correct, but I don't see the definition for __io, so I suspect that the function is not actually getting used. Best make this unconditional. The code is obviously derived from the ARM version, which uses a macro called __io, but you don't need this macro because you only support one SoC platform. Arnd
