       memory_cb - CardBus memory driver

       insmod memory_cb.o [pc_debug=n]

       Memory_cb  gives direct memory access to the address spaces of CardBus cards.  It provides
       character-mode devices for accessing a card's PCI configuration space, up  to  six  mapped
       memory or IO regions, and its expansion ROM space.  When loaded, memory_cb will allocate a
       free major device number.  For each card, it will report which address spaces  are  avail-
       able,  and  their  sizes.   Minor  numbers  have the form 'dddddsss', where 'ddddd' is the
       instance number and 'sss' is the memory space for that instance.  When memory_cb is  bound
       to a card, it will report its major and minor device numbers to cardmgr(8).

       The  default  memory card initialization script creates device special files for all eight
       card address spaces, though for a particular card,  some  of  these  may  be  unavailable.
       These devices have the following names:

	      The card's PCI configuration space.

	      The IO or memory spaces mapped by the card's six Base Address Registers.

	      The card's expansion ROM space.

       The  character special devices can be used to read and write arbitrary numbers of bytes to
       arbitrary locations.  The memory_cb driver can be bound to any card  regardless	of  func-

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