 10	  The VSC, GSC and HSC busses were used from the earliest 700-series
 11	  workstations up to and including the C360/J2240 workstations.  They
 12	  were also used in servers from the E-class to the K-class.  They
 13	  are not found in B1000, C3000, J5000, A500, L1000, N4000 and upwards.
 14	  If in doubt, say "Y".

 26	help
 27	  Say Y here to enable DMA management routines for the first
 28	  generation of PA-RISC cache-coherent machines.  Programs the
 29	  U2/Uturn chip in "Virtual Mode" and use the I/O MMU.

 31config GSC_LASI
 32	bool "Lasi I/O support"
 33	depends on GSC
 34	help
 35	  Say Y here to support the Lasi multifunction chip found in
 36	  many PA-RISC workstations & servers.	It includes interfaces
 37	  for a parallel port, serial port, NCR 53c710 SCSI, Apricot
 38	  Ethernet, Harmony audio, PS/2 keyboard & mouse, ISDN, telephony
 39	  and floppy.  Note that you must still enable all the individual
 40	  drivers for these chips.

 42config GSC_WAX
 43	bool "Wax I/O support"
 44	depends on GSC
 45	help
 46	  Say Y here to support the Wax multifunction chip found in some
 47	  older systems, including B/C/D/R class and 715/64, 715/80 and
 48	  715/100.  Wax includes an EISA adapter, a serial port (not always
 49	  used), a HIL interface chip and is also known to be used as the
 50	  GSC bridge for an X.25 GSC card.

 62	help
 63	  Say Y here to support the Dino & Cujo GSC to PCI bridges found in
 64	  machines from the B132 to the C360, the J2240 and the A180.  Some
 65	  GSC/HSC cards (eg gigabit & dual 100 Mbit Ethernet) have a Dino on
 66	  the card, and you also need to say Y here if you have such a card.
 67	  Note that Dino also supplies one of the serial ports on certain
 68	  machines.  If in doubt, say Y.

107	  Say Y here if you want to enable support for the Heartbeat,
108	  Disk/Network activities LEDs on some PA-RISC machines,
109	  or support for the LCD that can be found on recent material.
110	
111	  This has nothing to do with LED State support for A and E class.

116	bool "PDC chassis state codes support"
117	default y
118	help
119	  Say Y here if you want to enable support for Chassis codes.
120	  That includes support for LED State front panel as found on E
121	  class, and support for the GSP Virtual Front Panel (LED State and
122	  message logging)  as found on high end servers such as A, L and
123	  N-class.
124	  This driver will also display progress messages on LCD display,
125	  such as "INI", "RUN" and "FLT", and might thus clobber messages
126	  shown by the LED/LCD driver.
127	  This driver updates the state panel (LED and/or LCD) upon system
128	  state change (eg: boot, shutdown or panic).
129

138	  Say Y here if you want to enable support for Chassis warnings.
139	  This will add a proc entry '/proc/chassis' giving some information
140	  about the overall health state of the system.
141	  This includes NVRAM battery level, overtemp or failures such as
142	  fans or power units.

158	  To compile this driver as a module, choose M here.
159	  The module will be called pdc_stable.
