tty: move obsolete and broken generic_serial drivers to drivers/staging/generic_serial/
As planned by Arnd Bergmann, this moves the following drivers to the drivers/staging/generic_serial directory where they will be removed after 2.6.41 if no one steps up to claim them. generic_serial rio ser_a2232 sx vme_scc Cc: Arnd Bergmann <arnd@arndb.de> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Cc: Jiri Slaby <jslaby@suse.cz> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

- 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.

-** HostUniqueNum is the unique number from the host card that this RTA
-** is to be connected to.
-** RtaUniqueNum is the unique number of the RTA concerned. It will be ZERO
-** if the slot in the table is unused. If it is the same as the HostUniqueNum
-** then this slot represents a host card.
-** Flags contains current boot/route state info
-** SysPort is a value in the range 0-504, being the number of the first tty
-** on this RTA. Each RTA supports 8 ports. The SysPort value must be modulo 8.
-** SysPort 0-127 correspond to /dev/ttyr001 to /dev/ttyr128, with minor
-** numbers 0-127. SysPort 128-255 correspond to /dev/ttyr129 to /dev/ttyr256,
-** again with minor numbers 0-127, and so on for SysPorts 256-383 and 384-511
-** ID will be in the range 0-16 for a `known' RTA. ID will be 0xFFFF for an
-** unused slot/unknown ID etc.
-** The Topology array contains the ID of the unit connected to each of the
-** four links on this unit. The entry will be 0xFFFF if NOTHING is connected
-** to the link, or will be 0xFF00 if an UNKNOWN unit is connected to the link.
-** The Name field is a null-terminated string, upto 31 characters, containing
-** the 'cute' name that the sysadmin/users know the RTA by. It is permissible
-** for this string to contain any character in the range \040 to \176 inclusive.
-** In particular, ctrl sequences and DEL (0x7F, \177) are not allowed. The
-** special character '%' IS allowable, and needs no special action.

- ** We now need to insert a short boot section into
- ** the memory at the end of Sram2. This is normally (de)composed
- ** of the last eight bytes of the download code. The
- ** download has been assembled/compiled to expect to be
- ** loaded from 0x7FFF downwards. We have loaded it
- ** at some other address. The startup code goes into the small
- ** ram window at Sram2, in the last 8 bytes, which are really
- ** at addresses 0x7FF8-0x7FFF.
- **
- ** If the loadbase is, say, 0x7C00, then we need to branch to
- ** address 0x7BFE to run the host.bin startup code. We assemble
- ** this jump manually.
- **
- ** The two byte sequence 60 08 is loaded into memory at address
- ** 0x7FFE,F. This is a local branch to location 0x7FF8 (60 is nfix 0,
- ** which adds '0' to the .O register, complements .O, and then shifts
- ** it left by 4 bit positions, 08 is a jump .O+8 instruction. This will
- ** add 8 to .O (which was 0xFFF0), and will branch RELATIVE to the new
- ** location. Now, the branch starts from the value of .PC (or .IP or
- ** whatever the bloody register is called on this chip), and the .PC
- ** will be pointing to the location AFTER the branch, in this case
- ** .PC == 0x8000, so the branch will be to 0x8000+0xFFF8 = 0x7FF8.
- **
- ** A long branch is coded at 0x7FF8. This consists of loading a four
- ** byte offset into .O using nfix (as above) and pfix operators. The
- ** pfix operates in exactly the same way as the nfix operator, but
- ** without the complement operation. The offset, of course, must be
- ** relative to the address of the byte AFTER the branch instruction,
- ** which will be (urm) 0x7FFC, so, our final destination of the branch
- ** (loadbase-2), has to be reached from here. Imagine that the loadbase
- ** is 0x7C00 (which it is), then we will need to branch to 0x7BFE (which
- ** is the first byte of the initial two byte short local branch of the
- ** download code).
- **
- ** To code a jump from 0x7FFC (which is where the branch will start
- ** from) to 0x7BFE, we will need to branch 0xFC02 bytes (0x7FFC+0xFC02)=
- ** 0x7BFE.
- ** This will be coded as four bytes:
- ** 60 2C 20 02
- ** being nfix .O+0
- ** pfix .O+C
- ** pfix .O+0
- ** jump .O+2
- **
- ** The nfix operator is used, so that the startup code will be
- ** compatible with the whole Tp family. (lies, damn lies, it'll never
- ** work in a month of Sundays).
- **
- ** The nfix nyble is the 1s complement of the nyble value you
- ** want to load - in this case we wanted 'F' so we nfix loaded '0'.

-**
-** 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().

-** 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.

-** RIOParam is used to open or configure a port. You pass it a PortP,

-** or re-configured. You must also tell RIOParam if the device is a modem
-** device or not (i.e. top bit of minor number set or clear - take special
-** care when deciding on this!).
-** RIOParam neither flushes nor waits for drain, and is NOT preemptive.

-/*
- * 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.

- * Revision history:
- * Revision 1.33 2000/03/09 10:00:00 pvdl,wolff
- * - Fixed module and port counting
- * - Fixed signal handling
- * - Fixed an Ooops
- *
- * Revision 1.32 2000/03/07 09:00:00 wolff,pvdl
- * - Fixed some sx_dprintk typos
- * - added detection for an invalid board/module configuration
- *
- * Revision 1.31 2000/03/06 12:00:00 wolff,pvdl
- * - Added support for EISA
- *
- * Revision 1.30 2000/01/21 17:43:06 wolff
- * - Added support for SX+
- *
- * Revision 1.26 1999/08/05 15:22:14 wolff
- * - Port to 2.3.x
- * - Reformatted to Linus' liking.
- *
- * Revision 1.25 1999/07/30 14:24:08 wolff
- * Had accidentally left "gs_debug" set to "-1" instead of "off" (=0).
- *
- * Revision 1.24 1999/07/28 09:41:52 wolff
- * - I noticed the remark about use-count straying in sx.txt. I checked
- * sx_open, and found a few places where that could happen. I hope it's
- * fixed now.
- *
- * Revision 1.23 1999/07/28 08:56:06 wolff
- * - Fixed crash when sx_firmware run twice.
- * - Added sx_slowpoll as a module parameter (I guess nobody really wanted
- * to change it from the default... )
- * - Fixed a stupid editing problem I introduced in 1.22.
- * - Fixed dropping characters on a termios change.
- *
- * Revision 1.22 1999/07/26 21:01:43 wolff
- * Russell Brown noticed that I had overlooked 4 out of six modem control
- * signals in sx_getsignals. Ooops.
- *
- * Revision 1.21 1999/07/23 09:11:33 wolff
- * I forgot to free dynamically allocated memory when the driver is unloaded.
- *
- * Revision 1.20 1999/07/20 06:25:26 wolff
- * The "closing wait" wasn't honoured. Thanks to James Griffiths for
- * reporting this.
- *
- * Revision 1.19 1999/07/11 08:59:59 wolff
- * Fixed an oops in close, when an open was pending. Changed the memtest
- * a bit. Should also test the board in word-mode, however my card fails the
- * memtest then. I still have to figure out what is wrong...
- *
- * Revision 1.18 1999/06/10 09:38:42 wolff
- * Changed the format of the firmware revision from %04x to %x.%02x .
- *
- * Revision 1.17 1999/06/04 09:44:35 wolff
- * fixed problem: reference to pci stuff when config_pci was off...
- * Thanks to Jorge Novo for noticing this.
- *
- * Revision 1.16 1999/06/02 08:30:15 wolff
- * added/removed the workaround for the DCD bug in the Firmware.
- * A bit more debugging code to locate that...
- *
- * Revision 1.15 1999/06/01 11:35:30 wolff
- * when DCD is left low (floating?), on TA's the firmware first tells us
- * that DCD is high, but after a short while suddenly comes to the
- * conclusion that it is low. All this would be fine, if it weren't that
- * Unix requires us to send a "hangup" signal in that case. This usually
- * all happens BEFORE the program has had a chance to ioctl the device
- * into clocal mode..
- *
- * Revision 1.14 1999/05/25 11:18:59 wolff
- * Added PCI-fix.
- * Added checks for return code of sx_sendcommand.
- * Don't issue "reconfig" if port isn't open yet. (bit us on TA modules...)
- *
- * Revision 1.13 1999/04/29 15:18:01 wolff
- * Fixed an "oops" that showed on SuSE 6.0 systems.
- * Activate DTR again after stty 0.
- *
- * Revision 1.12 1999/04/29 07:49:52 wolff
- * Improved "stty 0" handling a bit. (used to change baud to 9600 assuming
- * the connection would be dropped anyway. That is not always the case,
- * and confuses people).
- * Told the card to always monitor the modem signals.
- * Added support for dynamic gs_debug adjustments.
- * Now tells the rest of the system the number of ports.
- *
- * Revision 1.11 1999/04/24 11:11:30 wolff
- * Fixed two stupid typos in the memory test.
- *
- * Revision 1.10 1999/04/24 10:53:39 wolff
- * Added some of Christian's suggestions.
- * Fixed an HW_COOK_IN bug (ISIG was not in I_OTHER. We used to trust the
- * card to send the signal to the process.....)
- *
- * Revision 1.9 1999/04/23 07:26:38 wolff
- * Included Christian Lademann's 2.0 compile-warning fixes and interrupt
- * assignment redesign.
- * Cleanup of some other stuff.
- *
- * Revision 1.8 1999/04/16 13:05:30 wolff
- * fixed a DCD change unnoticed bug.
- *
- * Revision 1.7 1999/04/14 22:19:51 wolff
- * Fixed typo that showed up in 2.0.x builds (get_user instead of Get_user!)
- *
- * Revision 1.6 1999/04/13 18:40:20 wolff
- * changed misc-minor to 161, as assigned by HPA.
- *
- * Revision 1.5 1999/04/13 15:12:25 wolff
- * Fixed use-count leak when "hangup" occurred.
- * Added workaround for a stupid-PCIBIOS bug.
- *
- *
- * Revision 1.4 1999/04/01 22:47:40 wolff
- * Fixed < 1M linux-2.0 problem.
- * (vremap isn't compatible with ioremap in that case)
- *
- * Revision 1.3 1999/03/31 13:45:45 wolff
- * Firmware loading is now done through a separate IOCTL.
- *
- * Revision 1.2 1999/03/28 12:22:29 wolff
- * rcs cleanup
- *
- * Revision 1.1 1999/03/28 12:10:34 wolff
- * Readying for release on 2.0.x (sorry David, 1.01 becomes 1.1 for RCS).
- *
- * Revision 0.12 1999/03/28 09:20:10 wolff
- * Fixed problem in 0.11, continueing cleanup.
- *
- * Revision 0.11 1999/03/28 08:46:44 wolff
- * cleanup. Not good.
- *
- * Revision 0.10 1999/03/28 08:09:43 wolff
- * Fixed loosing characters on close.
- *
- * Revision 0.9 1999/03/21 22:52:01 wolff
- * Ported back to 2.2.... (minor things)
- *
- * Revision 0.8 1999/03/21 22:40:33 wolff
- * Port to 2.0
- *
- * Revision 0.7 1999/03/21 19:06:34 wolff
- * Fixed hangup processing.
- *
- * Revision 0.6 1999/02/05 08:45:14 wolff
- * fixed real_raw problems. Inclusion into kernel imminent.
- *
- * Revision 0.5 1998/12/21 23:51:06 wolff
- * Snatched a nasty bug: sx_transmit_chars was getting re-entered, and it
- * shouldn't have. THATs why I want to have transmit interrupts even when
- * the buffer is empty.
- *
- * Revision 0.4 1998/12/17 09:34:46 wolff
- * PPP works. ioctl works. Basically works!
- *
- * Revision 0.3 1998/12/15 13:05:18 wolff
- * It works! Wow! Gotta start implementing IOCTL and stuff....
- *
- * Revision 0.2 1998/12/01 08:33:53 wolff
- * moved over to 2.1.130
- *
- * Revision 0.1 1998/11/03 21:23:51 wolff
- * Initial revision. Detects SX card.
