    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.)
