/*
* 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.
