Staging: delete tty drivers

Browse Source 
Delete the drivers/staging/tty drivers as no one has wanted to step up
and maintain and fix them.  This was discussed in commit
4a6514e6d0 (tty: move obsolete and broken
tty drivers to drivers/staging/tty/)

config STALLION
tristate "Stallion EasyIO or EC8/32 support"
depends on STALDRV && (ISA || EISA || PCI)
help
If you have an EasyIO or EasyConnection 8/32 multiport Stallion
card, then this is for you; say Y. Make sure to read
<file:Documentation/serial/stallion.txt>.
To compile this driver as a module, choose M here: the
module will be called stallion.
config ISTALLION
tristate "Stallion EC8/64, ONboard, Brumby support"
depends on STALDRV && (ISA || EISA || PCI)
help
If you have an EasyConnection 8/64, ONboard, Brumby or Stallion
serial multiport card, say Y here. Make sure to read
<file:Documentation/serial/stallion.txt>.
To compile this driver as a module, choose M here: the
module will be called istallion.
config DIGIEPCA
tristate "Digiboard Intelligent Async Support"
depends on SERIAL_NONSTANDARD && (ISA || EISA || PCI)
---help---
This is a driver for Digi International's Xx, Xeve, and Xem series
of cards which provide multiple serial ports. You would need
something like this to connect more than two modems to your Linux
box, for instance in order to become a dial-in server. This driver
supports the original PC (ISA) boards as well as PCI, and EISA. If
you have a card like this, say Y here and read the file
<file:Documentation/serial/digiepca.txt>.
To compile this driver as a module, choose M here: the
module will be called epca.
config RISCOM8
tristate "SDL RISCom/8 card support"
depends on SERIAL_NONSTANDARD
help
This is a driver for the SDL Communications RISCom/8 multiport card,
which gives you many serial ports. You would need something like
this to connect more than two modems to your Linux box, for instance
in order to become a dial-in server. If you have a card like that,
say Y here and read the file <file:Documentation/serial/riscom8.txt>.
Also it's possible to say M here and compile this driver as kernel
loadable module; the module will be called riscom8.
config SPECIALIX
tristate "Specialix IO8+ card support"
depends on SERIAL_NONSTANDARD
help
This is a driver for the Specialix IO8+ multiport card (both the
ISA and the PCI version) which gives you many serial ports. You
would need something like this to connect more than two modems to
your Linux box, for instance in order to become a dial-in server.
If you have a card like that, say Y here and read the file
<file:Documentation/serial/specialix.txt>. Also it's possible to say
M here and compile this driver as kernel loadable module which will be
called specialix.
config COMPUTONE
tristate "Computone IntelliPort Plus serial support"
depends on SERIAL_NONSTANDARD && (ISA || EISA || PCI)
---help---
This driver supports the entire family of Intelliport II/Plus
controllers with the exception of the MicroChannel controllers and
products previous to the Intelliport II. These are multiport cards,
which give you many serial ports. You would need something like this
to connect more than two modems to your Linux box, for instance in
order to become a dial-in server. If you have a card like that, say
Y here and read <file:Documentation/serial/computone.txt>.
To compile this driver as module, choose M here: the
module will be called ip2.
config SERIAL167
bool "CD2401 support for MVME166/7 serial ports"
depends on MVME16x
help
This is the driver for the serial ports on the Motorola MVME166,
167, and 172 boards. Everyone using one of these boards should say
Y here.

These are a few tty/serial drivers that either do not build,
or work if they do build, or if they seem to work, are for obsolete
hardware, or are full of unfixable races and no one uses them anymore.
If no one steps up to adopt any of these drivers, they will be removed
in the 2.6.41 release.

HARDWARE DESCRIPTION:
Introduction:
The IntelliPort-II and IntelliPort-IIEX products occupy a block of eight (8)
addresses in the host's I/O space.
Some addresses are used to transfer data to/from the board, some to transfer
so-called "mailbox" messages, and some to read bit-mapped status information.
While all the products in the line are functionally similar, some use a 16-bit
data path to transfer data while others use an 8-bit path. Also, the use of
command /status/mailbox registers differs slightly between the II and IIEX
branches of the family.
The host determines what type of board it is dealing with by reading a string of
sixteen characters from the board. These characters are always placed in the
fifo by the board's local processor whenever the board is reset (either from
power-on or under software control) and are known as the "Power-on Reset
Message." In order that this message can be read from either type of board, the
hardware registers used in reading this message are the same. Once this message
has been read by the host, then it has the information required to operate.
General Differences between boards:
The greatest structural difference is between the -II and -IIEX families of
product. The -II boards use the Am4701 dual 512x8 bidirectional fifo to support
the data path, mailbox registers, and status registers. This chip contains some
features which are not used in the IntelliPort-II products; a description of
these is omitted here. Because of these many features, it contains many
registers, too many to access directly within a small address space. They are
accessed by first writing a value to a "pointer" register. This value selects
the register to be accessed. The next read or write to that address accesses
the selected register rather than the pointer register.
The -IIEX boards use a proprietary design similar to the Am4701 in function. But
because of a simpler, more streamlined design it doesn't require so many
registers. This means they can be accessed directly in single operations rather
than through a pointer register.
Besides these differences, there are differences in whether 8-bit or 16-bit
transfers are used to move data to the board.
The -II boards are capable only of 8-bit data transfers, while the -IIEX boards
may be configured for either 8-bit or 16-bit data transfers. If the on-board DIP
switch #8 is ON, and the card has been installed in a 16-bit slot, 16-bit
transfers are supported (and will be expected by the standard loadware). The
on-board firmware can determine the position of the switch, and whether the
board is installed in a 16-bit slot; it supplies this information to the host as
part of the power-up reset message.
The configuration switch (#8) and slot selection do not directly configure the
hardware. It is up to the on-board loadware and host-based drivers to act
according to the selected options. That is, loadware and drivers could be
written to perform 8-bit transfers regardless of the state of the DIP switch or
slot (and in a diagnostic environment might well do so). Likewise, 16-bit
transfers could be performed as long as the card is in a 16-bit slot.
Note the slot selection and DIP switch selection are provided separately: a
board running in 8-bit mode in a 16-bit slot has a greater range of possible
interrupts to choose from; information of potential use to the host.
All 8-bit data transfers are done in the same way, regardless of whether on a
-II board or a -IIEX board.
The host must consider two things then: 1) whether a -II or -IIEX product is
being used, and 2) whether an 8-bit or 16-bit data path is used.
A further difference is that -II boards always have a 512-byte fifo operating in
each direction. -IIEX boards may use fifos of varying size; this size is
reported as part of the power-up message.
I/O Map Of IntelliPort-II and IntelliPort-IIEX boards:
(Relative to the chosen base address)
Addr R/W IntelliPort-II IntelliPort-IIEX
---- --- -------------- ----------------
0 R/W Data Port (byte) Data Port (byte or word)
1 R/W (Not used) (MSB of word-wide data written to Data Port)
2 R Status Register Status Register
2 W Pointer Register Interrupt Mask Register
3 R/W (Not used) Mailbox Registers (6 bits: 11111100)
4,5 -- Reserved for future products
6 -- Reserved for future products
7 R Guaranteed to have no effect
7 W Hardware reset of board.
Rules:
All data transfers are performed using the even i/o address. If byte-wide data
transfers are being used, do INB/OUTB operations on the data port. If word-wide
transfers are used, do INW/OUTW operations. In some circumstances (such as
reading the power-up message) you will do INB from the data port, but in this
case the MSB of each word read is lost. When accessing all other unreserved
registers, use byte operations only.

// the primary means of transferring data, commands, flow-control, and status
// information between the host and board.
//
#define FIFO_DATA 0
// Another way of passing information between the board and the host is
// through "mailboxes". Unlike a FIFO, a mailbox holds only a single byte of
// data. Writing data to the mailbox causes a status bit to be set, and
// potentially interrupting the intended receiver. The sender has some way to

// RESET & POWER-ON RESET MESSAGE
/*------------------------------------------------------------------------------
RESET:
The IntelliPort-II and -IIEX boards are reset in three ways: Power-up, channel
reset, and via a write to the reset register described above. For products using
the ISA bus, these three sources of reset are equvalent. For MCA and EISA buses,
the Power-up and channel reset sources cause additional hardware initialization
which should only occur at system startup time.
The third type of reset, called a "command reset", is done by writing any data
to the FIFO_RESET address described above. This resets the on-board processor,
FIFO, UARTS, and associated hardware.
This passes control of the board to the bootstrap firmware, which performs a
Power-On Self Test and which detects its current configuration. For example,
-IIEX products determine the size of FIFO which has been installed, and the
number and type of expansion boxes attached.
This and other information is then written to the FIFO in a 16-byte data block
to be read by the host. This block is guaranteed to be present within two (2)
seconds of having received the command reset. The firmware is now ready to
receive loadware from the host.
It is good practice to perform a command reset to the board explicitly as part
of your software initialization. This allows your code to properly restart from
a soft boot. (Many systems do not issue channel reset on soft boot).
Because of a hardware reset problem on some of the Cirrus Logic 1400's which are
used on the product, it is recommended that you reset the board twice, separated
by an approximately 50 milliseconds delay. (VERY approximately: probably ok to
be off by a factor of five. The important point is that the first command reset
in fact generates a reset pulse on the board. This pulse is guaranteed to last
less than 10 milliseconds. The additional delay ensures the 1400 has had the
chance to respond sufficiently to the first reset. Why not a longer delay? Much
more than 50 milliseconds gets to be noticeable, but the board would still work.
Once all 16 bytes of the Power-on Reset Message have been read, the bootstrap
firmware is ready to receive loadware.
Note on Power-on Reset Message format:
The various fields have been designed with future expansion in view.
Combinations of bitfields and values have been defined which define products
which may not currently exist. This has been done to allow drivers to anticipate
the possible introduction of products in a systematic fashion. This is not
intended to suggest that each potential product is actually under consideration.

// or an 8-port size. Whenever an 8-port box is used, the remaining 8
// ports leave gaps between existing channels. For that reason,
// expandable products must report a MAP of available channels. Since
// each UART supports four ports, we represent each UART found by a
// single bit. Using two bytes to supply the mapping information we
// report the presence or absence of up to 16 UARTS, or 64 ports in
// steps of 4 ports. For -IIEX products, the ports are numbered

// LOADWARE and DOWNLOADING CODE
//-------------------------------------
/*
Loadware may be sent to the board in two ways:
1) It may be read from a (binary image) data file block by block as each block
is sent to the board. This is only possible when the initialization is
performed by code which can access your file system. This is most suitable
for diagnostics and appications which use the interface library directly.
2) It may be hard-coded into your source by including a .h file (typically
supplied by Computone), which declares a data array and initializes every
element. This achieves the same result as if an entire loadware file had
been read into the array.
This requires more data space in your program, but access to the file system
is not required. This method is more suited to driver code, which typically
is running at a level too low to access the file system directly.
At present, loadware can only be generated at Computone.
All Loadware begins with a header area which has a particular format. This
includes a magic number which identifies the file as being (purportedly)
loadware, CRC (for the loader), and version information.

//
// Maximum total length of an outgoing data or in-line command block. The limit
// of 36 on data is quite arbitrary and based more on DOS memory limitations
// than the board interface. However, for commands, the maximum packet length is
// MAX_CMD_PACK_SIZE, because the field size for the count is only a few bits
// (see I2PACK.H) in such packets. For data packets, the count field size is not
// the limiting factor. As of this writing, MAX_OBUF_BLOCK < MAX_CMD_PACK_SIZE,

// buffer size is what is reported when the very first set of flow control
// status packets are received from the board. Therefore, to be robust, you must
// always fill the board to at least 80% of the current credit limit, else you
// might not give it enough to trigger a new report. These conditions are
// obtained here so long as the maximum output block size is less than 20% the
// size of the board's output buffers. This is true at present by "coincidence"
// or "infernal knowledge": the board's output buffers are at least 700 bytes
// long (20% = 140 bytes, at least). The 80% figure is "official", so the safest

#ifndef I2PACK_H
#define I2PACK_H 1
//-----------------------------------------------
// Revision History:
//
// 10 October 1991 MAG First draft
// 24 February 1992 MAG Additions for 1.4.x loadware
// 11 March 1992 MAG New status packets
//
//-----------------------------------------------
//------------------------------------------------------------------------------
// Packet Formats:
//
// Information passes between the host and board through the FIFO in packets.
// These have headers which indicate the type of packet. Because the fifo data
// path may be 16-bits wide, the protocol is constrained such that each packet
// is always padded to an even byte count. (The lower-level interface routines
// -- i2ellis.c -- are designed to do this).
//
// The sender (be it host or board) must place some number of complete packets
// in the fifo, then place a message in the mailbox that packets are available.
// Placing such a message interrupts the "receiver" (be it board or host), who
// reads the mailbox message and determines that there are incoming packets
// ready. Since there are no partial packets, and the length of a packet is
// given in the header, the remainder of the packet can be read without checking
// for FIFO empty condition. The process is repeated, packet by packet, until
// the incoming FIFO is empty. Then the receiver uses the outbound mailbox to
// signal the board that it has read the data. Only then can the sender place
// additional data in the fifo.
//------------------------------------------------------------------------------
//
//------------------------------------------------
// Definition of Packet Header Area
//------------------------------------------------
//
// Caution: these only define header areas. In actual use the data runs off
// beyond the end of these structures.
//
// Since these structures are based on sequences of bytes which go to the board,
// there cannot be ANY padding between the elements.
#pragma pack(1)
//----------------------------
// DATA PACKETS
//----------------------------
typedef struct _i2DataHeader
{
unsigned char i2sChannel; /* The channel number: 0-255 */
// -- Bitfields are allocated LSB first --
// For incoming data, indicates whether this is an ordinary packet or a
// special one (e.g., hot key hit).
unsigned i2sId : 2 __attribute__ ((__packed__));
// For tagging data packets. There are flush commands which flush only data
// packets bearing a particular tag. (used in implementing IntelliView and
// IntelliPrint). THE TAG VALUE 0xf is RESERVED and must not be used (it has
// meaning internally to the loadware).

// These two bits determine the type of packet sent/received.

} i2CmdHeader, *i2CmdHeaderPtr;
// Structure is immediately followed by the applicable data.
//---------------------------------------
// Flow Control Packets (Outbound)
//---------------------------------------
// One type of outbound command packet is so important that the entire structure
// is explicitly defined here. That is the flow-control packet. This is never
// sent by user-level code (as would be the commands to raise/lower DTR, for
// example). These are only sent by the library routines in response to reading
// incoming data into the buffers.
//
// The parameters inside the command block are maintained in place, then the
// block is sent at the appropriate time.
typedef struct _flowIn
{
i2CmdHeader hd; // Channel #, count, type (see above)
unsigned char fcmd; // The flow control command (37)
unsigned short asof; // As of byte number "asof" (LSB first!) I have room
// for "room" bytes
unsigned short room;

//----------------------------------------
// (Incoming) Status Packets
//----------------------------------------

/* Board configuration array.
* This array defines the hardware irq and address for up to IP2_MAX_BOARDS
* (4 supported per ip2_types.h) ISA board addresses and irqs MUST be specified,
* PCI and EISA boards are probed for and automagicly configed
* iff the addresses are set to 1 and 2 respectivily.
* 0x0100 - 0x03f0 == ISA
* 1 == PCI
* 2 == EISA
* 0 == (skip this board)
* This array defines the hardware addresses for them. Special
* addresses are EISA and PCI which go sniffing for boards.
* In a multiboard system the position in the array determines which port
* devices are assigned to each board:
* board 0 is assigned ttyF0.. to ttyF63,
* board 1 is assigned ttyF64 to ttyF127,
* board 2 is assigned ttyF128 to ttyF191,
* board 3 is assigned ttyF192 to ttyF255.
*
* In PCI and EISA bus systems each range is mapped to card in
* monotonically increasing slot number order, ISA position is as specified
* here.
* If the irqs are ALL set to 0,0,0,0 all boards operate in
* polled mode. For interrupt operation ISA boards require that the IRQ be
* specified, while PCI and EISA boards any nonzero entry
* will enable interrupts using the BIOS configured irq for the board.
* An invalid irq entry will default to polled mode for that card and print
* console warning.
* When the driver is loaded as a module these setting can be overridden on the
* modprobe command line or on an option line in /etc/modprobe.conf.
* If the driver is built-in the configuration must be
* set here for ISA cards and address set to 1 and 2 for PCI and EISA.
*
* Here is an example that shows most if not all possibe combinations:
*static ip2config_t ip2config =
*{
* {11,1,0,0}, // irqs
* { // Addresses
* 0x0308, // Board 0, ttyF0 - ttyF63// ISA card at io=0x308, irq=11
* 0x0001, // Board 1, ttyF64 - ttyF127//PCI card configured by BIOS
* 0x0000, // Board 2, ttyF128 - ttyF191// Slot skipped
* 0x0002 // Board 3, ttyF192 - ttyF255//EISA card configured by BIOS
* // but polled not irq driven
* }
*};
*/
/* this structure is zeroed out because the suggested method is to configure
* the driver as a module, set up the parameters with an options line in
* /etc/modprobe.conf and load with modprobe or kmod, the kernel
* module loader
*/
/* This structure is NOW always initialized when the driver is initialized.
* Compiled in defaults MUST be added to the io and irq arrays in
* ip2.c. Those values are configurable from insmod parameters in the
* case of modules or from command line parameters (ip2=io,irq) when
* compiled in.
