33 * BAH (SMC 8bit ARCnet chipset) k/dpi
34 *
35 * The SMC 8bit ARCnet chip family uses a register and a memory window, which
36 * we get passed via bus_space_tags and bus_space_handles.
37 *
38 * As the reset functionality differs between the Amiga boards (using the
39 * 90c26 chip) and middle-aged ISA boards (using the 90c56 chip), we have
40 * a sc_reset callback function in the softc, which does a stop function
41 * (reset and leave dead) or a reset function depending on whether the 2nd
42 * parameter is 0 or 1.
