Staging: delete generic_serial drivers

Browse Source 
No one has steped up to claim them, so as described in commit
4c37705877 (tty: move obsolete and broken
generic_serial drivers to drivers/staging/generic_serial/), they are now
deleted from the system.

config A2232
tristate "Commodore A2232 serial support (EXPERIMENTAL)"
depends on EXPERIMENTAL && ZORRO && BROKEN
---help---
This option supports the 2232 7-port serial card shipped with the
Amiga 2000 and other Zorro-bus machines, dating from 1989. At
a max of 19,200 bps, the ports are served by a 6551 ACIA UART chip
each, plus a 8520 CIA, and a master 6502 CPU and buffer as well. The
ports were connected with 8 pin DIN connectors on the card bracket,
for which 8 pin to DB25 adapters were supplied. The card also had
jumpers internally to toggle various pinning configurations.
This driver can be built as a module; but then "generic_serial"
will also be built as a module. This has to be loaded before
"ser_a2232". If you want to do this, answer M here.
config SX
tristate "Specialix SX (and SI) card support"
depends on SERIAL_NONSTANDARD && (PCI || EISA || ISA) && BROKEN
help
This is a driver for the SX and SI multiport serial cards.
Please read the file <file:Documentation/serial/sx.txt> for details.
This driver can only be built as a module ( = code which can be
inserted in and removed from the running kernel whenever you want).
The module will be called sx. If you want to do that, say M here.
config RIO
tristate "Specialix RIO system support"
depends on SERIAL_NONSTANDARD && BROKEN
help
This is a driver for the Specialix RIO, a smart serial card which
drives an outboard box that can support up to 128 ports. Product
information is at <http://www.perle.com/support/documentation.html#multiport>.
There are both ISA and PCI versions.
config RIO_OLDPCI
bool "Support really old RIO/PCI cards"
depends on RIO
help
Older RIO PCI cards need some initialization-time configuration to
determine the IRQ and some control addresses. If you have a RIO and
this doesn't seem to work, try setting this to Y.

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.

**
** How to use this file:
**
** To send a command down a rup, you need to allocate a command block, fill
** in the packet information, fill in the command number, fill in the pre-
** and post- functions and arguments, and then add the command block to the
** queue of command blocks for the port in question. When the port is idle,
** then the pre-function will be called. If this returns RIO_FAIL then the
** command will be re-queued and tried again at a later date (probably in one
** clock tick). If the pre-function returns NOT RIO_FAIL, then the command
** packet will be queued on the RUP, and the txcontrol field set to the
** command number. When the txcontrol field has changed from being the
** command number, then the post-function will be called, with the argument
** specified earlier, a pointer to the command block, and the value of
** txcontrol.
**
** To allocate a command block, call RIOGetCmdBlk(). This returns a pointer
** to the command block structure allocated, or NULL if there aren't any.
** The block will have been zeroed for you.
**
** The structure has the following fields:
**
** struct CmdBlk
** {
** struct CmdBlk *NextP; ** Pointer to next command block **
** struct PKT Packet; ** A packet, to copy to the rup **
** int (*PreFuncP)(); ** The func to call to check if OK **
** int PreArg; ** The arg for the func **
** int (*PostFuncP)(); ** The func to call when completed **
** int PostArg; ** The arg for the func **
** };
**
** You need to fill in ALL fields EXCEPT NextP, which is used to link the
** blocks together either on the free list or on the Rup list.
**
** Packet is an actual packet structure to be filled in with the packet
** information associated with the command. You need to fill in everything,
** as the command processor doesn't process the command packet in any way.
**
** The PreFuncP is called before the packet is enqueued on the host rup.
** PreFuncP is called as (*PreFuncP)(PreArg, CmdBlkP);. PreFuncP must
** return !RIO_FAIL to have the packet queued on the rup, and RIO_FAIL
** if the packet is NOT to be queued.
**
** The PostFuncP is called when the command has completed. It is called
** as (*PostFuncP)(PostArg, CmdBlkP, txcontrol);. PostFuncP is not expected
** to return a value. PostFuncP does NOT need to free the command block,
** as this happens automatically after PostFuncP returns.
**
** Once the command block has been filled in, it is attached to the correct
** queue by calling RIOQueueCmdBlk( HostP, Rup, CmdBlkP ) where HostP is
** a pointer to the struct Host, Rup is the NUMBER of the rup (NOT a pointer
** to it!), and CmdBlkP is the pointer to the command block allocated using
** RIOGetCmdBlk().

** full. So, when we come in here, we need to test if any
** ports are in this condition, and re-open the port before
** we try to send any more data to it. Now, the re-booted

** The Scam, based on email from jeremyr@bugs.specialix.co.uk....
**
** To send a command on a particular port, you put a packet with the
** command bit set onto the port. The command bit is in the len field,
** and gets ORed in with the actual byte count.
**
** When you send a packet with the command bit set the first
** data byte (data[0]) is interpreted as the command to execute.
** It also governs what data structure overlay should accompany the packet.
** Commands are defined in cirrus/cirrus.h
**
** If you want the command to pre-emt data already on the queue for the
** port, set the pre-emptive bit in conjunction with the command bit.
** It is not defined what will happen if you set the preemptive bit
** on a packet that is NOT a command.
**
** Pre-emptive commands should be queued at the head of the queue using
** add_start(), whereas normal commands and data are enqueued using
** add_end().
**
** Most commands do not use the remaining bytes in the data array. The
** exceptions are OPEN MOPEN and CONFIG. (NB. As with the SI CONFIG and
** OPEN are currently analogous). With these three commands the following
** 11 data bytes are all used to pass config information such as baud rate etc.
** The fields are also defined in cirrus.h. Some contain straightforward
** information such as the transmit XON character. Two contain the transmit and
** receive baud rates respectively. For most baud rates there is a direct
** mapping between the rates defined in <sys/termio.h> and the byte in the
** packet. There are additional (non UNIX-standard) rates defined in
** /u/dos/rio/cirrus/h/brates.h.
**
** The rest of the data fields contain approximations to the Cirrus registers
** that are used to program number of bits etc. Each registers bit fields is
** defined in cirrus.h.
**
** NB. Only use those bits that are defined as being driver specific
** or common to the RTA and the driver.
**
** All commands going from RTA->Host will be dealt with by the Host code - you
** will never see them. As with the SI there will be three fields to look out
** for in each phb (not yet defined - needs defining a.s.a.p).
**
** modem_status - current state of handshake pins.
**
** port_status - current port status - equivalent to hi_stat for SI, indicates
** if port is IDLE_OPEN, IDLE_CLOSED etc.
**
** break_status - bit X set if break has been received.
**
** Happy hacking.

/***************************** Documentation ************************/
/*
* This driver is in EXPERIMENTAL state. That means I could not find
* someone with five A2232 boards with 35 ports running at 19200 bps
* at the same time and test the machine's behaviour.
* However, I know that you can performance-tweak this driver (see
* the source code).
* One thing to consider is the time this driver consumes during the
* Amiga's vertical blank interrupt. Everything that is to be done
* _IS DONE_ when entering the vertical blank interrupt handler of
* this driver.
* However, it would be more sane to only do the job for only ONE card
* instead of ALL cards at a time; or, more generally, to handle only
* SOME ports instead of ALL ports at a time.
* However, as long as no-one runs into problems I guess I shouldn't
* change the driver as it runs fine for me :) .
*
* Version history of this file:
* 0.4 Resolved licensing issues.
* 0.3 Inclusion in the Linux/m68k tree, small fixes.
* 0.2 Added documentation, minor typo fixes.
* 0.1 Initial release.
*
* TO DO:
* - Handle incoming BREAK events. I guess "Stevens: Advanced
* Programming in the UNIX(R) Environment" is a good reference
* on what is to be done.
* - When installing as a module, don't simply 'printk' text, but
* send it to the TTY used by the user.
*
* THANKS TO:
* - Jukka Marin (65EC02 code).
* - The other NetBSD developers on whose A2232 driver I had a
* pretty close look. However, I didn't copy any code so it
* is okay to put my code under the GPL and include it into
* Linux.
