36 .Nd sbus pcmcia bridge
38 # only needed for 32bit sparcs (remove the options line on sparc64):
39 .Cd "options FULL_SPARC_BUS_SPACE"
40 .Cd "nell* at sbus? slot ? offset ? flags 0"
41 .Cd "pcmcia* at nell? controller ? socket ?"
45 is a pcmcia bridge for the sbus.
46 It is also known as STP4020, the name
47 of the chipset used to implement it, and has SUN part number 501-2367.
49 The firmware assigns two interrupt levels to the nell, but the driver only
50 needs a single interrupt.
51 Depending on distribution of interrupt levels on your machine you might
52 prefer the driver to use either the first (use flags value 0) or the second
57 instance creates a kernel thread, named like the instance.
58 This thread is used to watch for card insertions and removals, and
59 handling the attachment and initialization of the card's driver.
