    sh: Allow use of GENERIC_IOMAP · 15444a89
    David McKay 提交于
    The synopsys PCI cell used in the later STMicro chips requires code to
    be run in order to do IO cycles, rather than just memory mapping the IO
    space. Rather than extending the existing SH infrastructure to allow
    this, use the GENERIC_IOMAP implmentation to save re-inventing the
    wheel.
    
    This set of changes allows the SH to be built with GENERIC_IOMAP
    enabled, it just ifdef's out the functions provided by the GENERIC_IOMAP
    implementation, and provides a few required missing functions.
