4. Technical Description
EOF of stp4020 driver
---------------------
The stp4020 device driver supports an Sbus <-> PCMCIA adapter bridge.
This hardware was never particularly common, and was potentially used in
Sun Ultra 1 and Ultra 2 systems. (Theoretically it could have been used
some Enterprise class Sbus systems (sunfire, starfire, campfire), but
its unlikely that this was ever actually done in practice.
Note that recently the SBus based workstations were officially EOF'd (although
code in ON still remains for them) and will not be supported in next
release of Solaris. (See PSARC 2009/572.)
Note also that PCMCIA is a very slow legacy bus, and unlikely to be useful
to users with more modern systems.
The upshot of this is that we feel the time is ripe to eliminate the support
for the stp4020 driver from OpenSolaris.
NOTE:
Furthermore, after the removal of Tadpole SPARCLE (PSARC 2009/538),
its unlikely that there are any folks using PCMCIA on SPARC anymore,
and certainly not with SPARC and OpenSolaris. It would be a good
idea to investigate the idea of removing the PCMCIA and Cardbus
components from SPARC as part of another case.
