-/*======================================================================
-
- A PCMCIA token-ring driver for IBM-based cards
-
- This driver supports the IBM PCMCIA Token-Ring Card.
- Written by Steve Kipisz, kipisz@vnet.ibm.com or
- bungy@ibm.net
-
- Written 1995,1996.
-
- This code is based on pcnet_cs.c from David Hinds.
-
- V2.2.0 February 1999 - Mike Phillips phillim@amtrak.com
-
- Linux V2.2.x presented significant changes to the underlying
- ibmtr.c code. Mainly the code became a lot more organized and
- modular.
-
- This caused the old PCMCIA Token Ring driver to give up and go
- home early. Instead of just patching the old code to make it
- work, the PCMCIA code has been streamlined, updated and possibly
- improved.
-
- This code now only contains code required for the Card Services.
- All we do here is set the card up enough so that the real ibmtr.c
- driver can find it and work with it properly.
-
- i.e. We set up the io port, irq, mmio memory and shared ram
- memory. This enables ibmtr_probe in ibmtr.c to find the card and
- configure it as though it was a normal ISA and/or PnP card.
-
- CHANGES
-
- v2.2.5 April 1999 Mike Phillips (phillim@amtrak.com)
- Obscure bug fix, required changed to ibmtr.c not ibmtr_cs.c
-
- v2.2.7 May 1999 Mike Phillips (phillim@amtrak.com)
- Updated to version 2.2.7 to match the first version of the kernel
- that the modification to ibmtr.c were incorporated into.
-
- v2.2.17 July 2000 Burt Silverman (burts@us.ibm.com)
- Address translation feature of PCMCIA controller is usable so
- memory windows can be placed in High memory (meaning above
- 0xFFFFF.)
