       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 Transla-
       tion  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.
