    sh: hw-breakpoints: Add preliminary support for SH-4A UBC. · 09a07294

    This adds preliminary support for the SH-4A UBC to the hw-breakpoints API.
    Presently only a single channel is implemented, and the ptrace interface
    still needs to be converted. This is the first step to cleaning up the
    long-standing UBC mess, making the UBC more generally accessible, and
    finally making it SMP safe.
    
    An additional abstraction will be layered on top of this as with the perf
    events code to permit the various CPU families to wire up support for
    their own specific UBCs, as many variations exist.
