       ftl_cs - Flash Translation Layer driver for PCMCIA memory cards


       insmod ftl_cs.o [pc_debug=n] [major_dev=n]


       Flash  memory  devices  typically  need  to  be  erased before they are
       written, and most flash devices can  only  be  erased  on  large  block
       boundaries  like  64K  or  128K.   The  Flash Translation Layer driver,
       ftl_cs, implements a sort of virtual  sector-addressable  block  device
       that  hides  the  details of erase operations.  Using the FTL driver, a
       flash memory card can be treated as an ordinary block device.

       The ftl_cs driver allocates a major device number when  it  is  loaded.
       Minor device numbers have a bitwise layout of ’dddrrppp’.  ’ddd’ is the
       device number, with one card counting  as  one  device.   ’rr’  is  the
       common-memory  region number, generally 0.  And ’ppp’ selects a logical
       partition within the FTL region.

       The default configuration script for FTL devices will  create  a  block
       device  with the name of the form ’/dev/ftl{d}c{r}’, where ’{d}’ is the
       device number and ’{r}’ is the region number, that spans the entire FTL
       region.   It  also  creates devices ’/dev/ftl{d}c{r}p[1-4]’ pointing to
       partitions 1 through 4 within this FTL region.

       An FTL region must be formatted before use.   The  formatting  utility,
       ftl_format,  needs  to  write  to  the  corresponding raw memory device
       rather than the FTL device interface.


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

              Selects the major device number to  allocate  for  FTL  devices.
              The default is to pick any available major number.
