system LED on or off. Unlike the EBus LED AUXIO register where the
remaining bits are unused the upper bits of the SBus AUXIO register
are used to control other things like the link test enable pin of

resources in ebus.c rev. 1.22 and collapse the resource allocation for
both the EBus and SBus variants into auxio_attach_common().

the resource without allocating it.

The auxio device provides auxiliary I/O functions and is found on various
SBus/EBus UltraSPARC models. At present, only front panel LED is
controlled by this driver.
