Remove long-unmaintained ftape driver subsystem.

It's bitrotten, long unmaintained, long hidden under BROKEN_ON_SMP,
etc.  As scheduled in feature-removal-schedule.txt, and ack'd several
times on lkml.

If you have a tape drive that is connected to your floppy
controller, say Y here.
Some tape drives (like the Seagate "Tape Store 3200" or the Iomega
"Ditto 3200" or the Exabyte "Eagle TR-3") come with a "high speed"
controller of their own. These drives (and their companion
controllers) are also supported if you say Y here.
If you have a special controller (such as the CMS FC-10, FC-20,
Mountain Mach-II, or any controller that is based on the Intel 82078
FDC like the high speed controllers by Seagate and Exabyte and
Iomega's "Ditto Dash") you must configure it by selecting the
appropriate entries from the "Floppy tape controllers" sub-menu
below and possibly modify the default values for the IRQ and DMA
channel and the IO base in ftape's configuration menu.
If you want to use your floppy tape drive on a PCI-bus based system,
please read the file <file:drivers/char/ftape/README.PCI>.
The ftape kernel driver is also available as a runtime loadable
module. To compile this driver as a module, choose M here: the
module will be called ftape.

Some notes for ftape users with PCI motherboards:
=================================================
The problem:
------------
There have been some problem reports from people using PCI-bus based
systems getting overrun errors.
I wasn't able to reproduce these until I ran ftape on a Intel Plato
(Premiere PCI II) motherboard with bios version 1.00.08AX1.
It turned out that if GAT (Guaranteed Access Timing) is enabled (?)
ftape gets a lot of overrun errors.
The problem disappears when disabling GAT in the bios.
Note that Intel removed this setting (permanently disabled) from the
1.00.10AX1 bios !
It looks like that if GAT is enabled there are often large periods
(greater than 120 us !??) on the ISA bus that the DMA controller cannot
service the floppy disk controller.
I cannot imagine this being acceptable in a decent PCI implementation.
Maybe this is a `feature' of the chipset. I can only speculate why
Intel choose to remove the option from the latest Bios...
The lesson of this all is that there may be other motherboard
implementations having the same of similar problems.
If you experience a lot of overrun errors during a backup to tape,
see if there is some setting in the Bios that may influence the
bus timing.
I judge this a hardware problem and not a limitation of ftape ;-)
My DOS backup software seems to be suffering from the same problems
and even refuses to run at 1 Mbps !
Ftape will reduce the data-rate from 1 Mbps to 500 Kbps if the number
of overrun errors on a track exceeds a threshold.
Possible solutions:
-------------------
Some of the problems were solved by upgrading the (flash) bios.
Other suggest that it has to do with the FDC being on the PCI
bus, but that is not the case with the Intel Premiere II boards.
[If upgrading the bios doesn't solve the problem you could try
a floppy disk controller on the isa-bus].
Here is a list of systems and recommended BIOS settings:
Intel Premiere PCI (Revenge):
Bios version 1.00.09.AF2 is reported to work.
Intel Premiere PCI II (Plato):
Bios version 1.00.10.AX1 and version 11 beta are ok.
If using version 1.00.08.AX1, GAT must be disabled !
ASUS PCI/I-SP3G:
Preferred settings: ISA-GAT-mode : disabled
DMA-linebuffer-mode : standard
ISA-masterbuffer-mode : standard
DELL Dimension XPS P90
Bios version A2 is reported to be broken, while bios version A5 works.
You can get a flash bios upgrade from http://www.dell.com
To see if you're having the GAT problem, try making a backup
under DOS. If it's very slow and often repositions you're
probably having this problem.

The entire guts of this program was written by dosemu, modified to
record reads and writes to the ports in the 0x180-0x188 address space,
while running the CMS program TAPE.EXE V2.0.5 supplied with the drive.
Modified to use an array of addresses and generally cleaned up (made
much shorter) 4 June 94, dosemu isn't that good at writing short code it
would seem :-). Made independent of 0x180, but I doubt it will work
at any other address.
Modified for distribution with ftape source. 21 June 94, SJL.
Modifications on 20 October 95, by Daniel Cohen (catman@wpi.edu):
Modified to support different DMA, IRQ, and IO Ports. Borland's
Turbo Debugger in virtual 8086 mode (TD386.EXE with hardware breakpoints
provided by the TDH386.SYS Device Driver) was used on the CMS program
TAPE V4.0.5. I set breakpoints on I/O to ports 0x180-0x187. Note that
CMS's program will not successfully configure the tape drive if you set
breakpoints on IO Reads, but you can set them on IO Writes without problems.
Known problems:
- You can not use DMA Channels 5 or 7.
Modification on 29 January 96, by Daniel Cohen (catman@wpi.edu):
Modified to only accept IRQs 3 - 7, or 9. Since we can only send a 3 bit
number representing the IRQ to the card, special handling is required when
IRQ 9 is selected. IRQ 2 and 9 are the same, and we should request IRQ 9
from the kernel while telling the card to use IRQ 2. Thanks to Greg
Crider (gcrider@iclnet.org) for finding and locating this bug, as well as
testing the patch.
Modification on 11 December 96, by Claus Heine (claus@momo.math.rwth-aachen.de):
Modified a little to use variahle ft_fdc_base, ft_fdc_irq, ft_fdc_dma
instead of preprocessor symbols. Thus we can compile this into the module
or kernel and let the user specify the options as command line arguments.
