       dummy_cs - PCMCIA dummy device driver


       insmod dummy_cs.o [pc_debug=n] [free_ports=n] [irq_list=i,j,...]


       The   dummy_cs   module   has  two  purposes.   It  is  intended  as  a
       demonstration of how to write the PCMCIA interface code  for  a  client
       driver,  and  the source code is heavily commented.  It is also written
       to function as a sort of generic ‘‘point enabler’’: when bound  to  any
       PCMCIA  IO  card,  it  will  read  the card’s Configuration Information
       Structure, and configure the  card  appropriately.   The  configuration
       includes  setting  up  IO  and memory windows, configuring the card for
       interrupts, and initializing the card’s PCMCIA configuration registers.

       It   turns   out  that  many  cards  report  incomplete  or  inaccurate
       configuration  information,  due  to  vendor   carelessness   and   the
       complexity  of the data format.  A vendor driver can generally take for
       granted many configuration details, so there is not much incentive  for
       vendors  to ensure that the on-card information is complete.  Thus, the
       dummy_cs module is  limited  by  its  generality:  since  it  makes  no
       assumptions  about  card  types,  it  is  forced  to  rely  on the card
       information, for better or worse.


              Selects the PCMCIA debugging  level.   This  parameter  is  only
              available  if  the module is compiled with debugging enabled.  A
              non-zero value enables debugging.

              A flag indicating if the IO ports allocated for the card  should
              be  freed  from the kernel resource maps.  This is useful if the
              dummy driver is being used to configure a  card  in  preparation
              for  loading a specific PCMCIA-unaware driver.  The default is 0

              Specifies the set of interrupts that may be  allocated  by  this
