     * BAH (SMC 8bit ARCnet chipset) k/dpi
     *
     * The SMC 8bit ARCnet chip family uses a register and a memory window, which
     * we get passed via bus_space_tags and bus_space_handles.
     *
     * As the reset functionality differs between the Amiga boards (using the
     * 90c26 chip) and middle-aged ISA boards (using the 90c56 chip), we have
     * a sc_reset callback function in the softc, which does a stop function
     * (reset and leave dead) or a reset function depending on wether the 2nd
     * parameter is 0 or 1.
