[PATCH] DIGIEPCA: Remove long-obsolete digiepca driver.

[Robert P. J. Day]

Given that the removal of this driver has been under discussion for
over a year:

  http://lkml.org/lkml/2006/10/26/231

it would seem time to get rid of it.

-NOTE:  This driver is obsolete.  Digi provides a 2.6 driver (dgdm) at
-http://www.digi.com for PCI cards.  They no longer maintain this driver,
-and have no 2.6 driver for ISA cards.
-
-This driver requires a number of user-space tools.  They can be acquired from
-http://www.digi.com, but only works with 2.4 kernels.
-
-
-The Digi Intl. epca driver.
-----------------------------
-The Digi Intl. epca driver for Linux supports the following boards:
-
-Digi PC/Xem, PC/Xr, PC/Xe, PC/Xi, PC/Xeve
-Digi EISA/Xem, PCI/Xem, PCI/Xr
-
-Limitations:
-------------
-Currently the driver only autoprobes for supported PCI boards.
-
-The Linux MAKEDEV command does not support generating the Digiboard
-Devices.  Users executing digiConfig to setup EISA and PC series cards
-will have their device nodes automatically constructed (cud?? for ~CLOCAL,
-and ttyD?? for CLOCAL).  Users wishing to boot their board from the LILO
-prompt, or those users booting PCI cards may use buildDIGI to construct
-the necessary nodes.
-
-Notes:
-------
-This driver may be configured via LILO.  For users who have already configured
-their driver using digiConfig, configuring from LILO will override previous
-settings.  Multiple boards may be configured by issuing multiple LILO command
-lines.  For examples see the bottom of this document.
-
-Device names start at 0 and continue up.  Beware of this as previous Digi
-drivers started device names with 1.
-
-PCI boards are auto-detected and configured by the driver.  PCI boards will
-be allocated device numbers (internally) beginning with the lowest PCI slot
-first.  In other words a PCI card in slot 3 will always have higher device
-nodes than a PCI card in slot 1.
-
-LILO config examples:
----------------------
-Using LILO's APPEND command, a string of comma separated identifiers or
-integers can be used to configure supported boards.  The six values in order
-are:
-
-   Enable/Disable this card or Override,
-   Type of card: PC/Xe (AccelePort) (0), PC/Xeve (1), PC/Xem or PC/Xr (2),
-                 EISA/Xem (3), PC/64Xe (4), PC/Xi (5),
-   Enable/Disable alternate pin arrangement,
-   Number of ports on this card,
-   I/O Port where card is configured (in HEX if using string identifiers),
-   Base of memory window (in HEX if using string identifiers),
-
-NOTE : PCI boards are auto-detected and configured.  Do not attempt to
-configure PCI boards with the LILO append command.  If you wish to override
-previous configuration data (As set by digiConfig), but you do not wish to
-configure any specific card (Example if there are PCI cards in the system)
-the following override command will accomplish this:
--> append="digi=2"
-
-Samples:
-   append="digiepca=E,PC/Xe,D,16,200,D0000"
-                  or
-   append="digi=1,0,0,16,512,851968"
-
-Supporting Tools:
------------------
-Supporting tools include digiDload, digiConfig, buildPCI, and ditty.  See
-drivers/char/README.epca for more details.  Note,
-this driver REQUIRES that digiDload be executed prior to it being used.
-Failure to do this will result in an ENODEV error.
-
-Documentation:
---------------
-Complete documentation for this product may be found in the tool package.
