--*!
--*! Revision 1.5 1999/10/27 12:39:37 bjornw
--*! Disabled superuser check. Anyone can now set the time.
--*!
--*! Revision 1.4 1999/09/02 13:27:46 pkj

-- * Revision 1.2 2002/05/27 15:38:42 johana
-- * Made it compile without warnings on Linux 2.4.
-- * (includes, wait_queue, PROC_FS and snprintf)
-- *
-- * Revision 1.1 2002/05/27 15:32:25 johana
-- * arch/etrax100/kernel/fasttimer.c v1.8 from the elinux tree.
-- *
-- * Revision 1.8 2001/11/27 13:50:40 pkj
-- * Disable interrupts while stopping the timer and while modifying the
-- * list of active timers in timer1_handler() as it may be interrupted
-- * by other interrupts (e.g., the serial interrupt) which may add fast
-- * timers.
-- *
-- * Revision 1.7 2001/11/22 11:50:32 pkj
-- * * Only store information about the last 16 timers.
-- * * proc_fasttimer_read() now uses an allocated buffer, since it
-- * requires more space than just a page even for only writing the
-- * last 16 timers. The buffer is only allocated on request, so
-- * unless /proc/fasttimer is read, it is never allocated.
-- * * Renamed fast_timer_started to fast_timers_started to match
-- * fast_timers_added and fast_timers_expired.
-- * * Some clean-up.
-- *
-- * Revision 1.6 2000/12/13 14:02:08 johana
-- * Removed volatile for fast_timer_list

-- * Added DEBUG_LOG, added som cli() and cleanup
-- *
-- * Revision 1.4 2000/12/05 13:48:50 johana
-- * Added range check when writing proc file, modified timer int handling
-- *
-- * Revision 1.3 2000/11/23 10:10:20 johana
-- * More debug/logging possibilities.
-- * Moved GET_JIFFIES_USEC() to timex.h and time.c
-- *
-- * Revision 1.2 2000/11/01 13:41:04 johana
-- * Clean up and bugfixes.
-- * Created new do_gettimeofday_fast() that gets a timeval struct
-- * with time based on jiffies and *R_TIMER0_DATA, uses a table
-- * for fast conversion of timer value to microseconds.
-- * (Much faster the standard do_gettimeofday() and we don't really
-- * wan't to use the true time - we wan't the "uptime" so timers don't screw up
-- * when we change the time.
-- * TODO: Add efficient support for continuous timers as well.
-- *
-- * Revision 1.1 2000/10/26 15:49:16 johana
-- * Added fasttimer, highresolution timers.

-+ *
-+ * Changelog:
-+ * 01-31-2000 DMW Created
-+ * 09-18-2000 SJH Moved structure out of the Disk-On-Chip drivers
-+ * so it can be used by other NAND flash device
-+ * drivers. I also changed the copyright since none
-+ * of the original contents of this file are specific
-+ * to DoC devices. David can whack me with a baseball
-+ * bat later if I did something naughty.
-+ * 10-11-2000 SJH Added private NAND flash structure for driver
-+ * 10-24-2000 SJH Added prototype for 'nand_scan' function
-+ * 10-29-2001 TG changed nand_chip structure to support
-+ * hardwarespecific function for accessing control lines
-+ * 02-21-2002 TG added support for different read/write adress and
-+ * ready/busy line access function
-+ * 02-26-2002 TG added chip_delay to nand_chip structure to optimize
-+ * command delay times for different chips
-+ * 04-28-2002 TG OOB config defines moved from nand.c to avoid duplicate
-+ * defines in jffs2/wbuf.c
-+ * 08-07-2002 TG forced bad block location to byte 5 of OOB, even if
-+ * CONFIG_MTD_NAND_ECC_JFFS2 is not set
-+ * 08-10-2002 TG extensions to nand_chip structure to support HW-ECC
-+ *
-+ * 08-29-2002 tglx nand_chip structure: data_poi for selecting
-+ * internal / fs-driver buffer
-+ * support for 6byte/512byte hardware ECC
-+ * read_ecc, write_ecc extended for different oob-layout
-+ * oob layout selections: NAND_NONE_OOB, NAND_JFFS2_OOB,
-+ * NAND_YAFFS_OOB
-+ * 11-25-2002 tglx Added Manufacturer code FUJITSU, NATIONAL
-+ * Split manufacturer and device ID structures
-+ *
-+ * 02-08-2004 tglx added option field to nand structure for chip anomalities
-+ * 05-25-2004 tglx added bad block table support, ST-MICRO manufacturer id
-+ * update of nand_chip structure description
-+ * 01-17-2005 dmarlin added extended commands for AG-AND device and added option
-+ * for BBT_AUTO_REFRESH.
-+ * 01-20-2005 dmarlin added optional pointer to hardware specific callback for
-+ * extra error status checks.

-+ * Snitched from drivers/mtd/nand_base.c
-+ * Modified to run outside Linux.
-+ * #if 0'd to remove non-essential functionality
-+ *
-+ * Overview:
-+ * This is the generic MTD driver for NAND flash devices. It should be
-+ * capable of working with almost all NAND chips currently available.
-+ * Basic support for AG-AND chips is provided.
-+ *
-+ * Additional technical information is available on
-+ * http://www.linux-mtd.infradead.org/tech/nand.html
-+ *
-+ * Copyright (C) 2000 Steven J. Hill (sjhill@realitydiluted.com)
-+ * 2002 Thomas Gleixner (tglx@linutronix.de)
-+ *
-+ * 02-08-2004 tglx: support for strange chips, which cannot auto increment
-+ * pages on read / read_oob
-+ *
-+ * 03-17-2004 tglx: Check ready before auto increment check. Simon Bayes
-+ * pointed this out, as he marked an auto increment capable chip
-+ * as NOAUTOINCR in the board driver.
-+ * Make reads over block boundaries work too
-+ *
-+ * 04-14-2004 tglx: first working version for 2k page size chips
-+ *
-+ * 05-19-2004 tglx: Basic support for Renesas AG-AND chips
-+ *
-+ * 09-24-2004 tglx: add support for hardware controllers (e.g. ECC) shared
-+ * among multiple independend devices. Suggestions and initial patch
-+ * from Ben Dooks <ben-mtd@fluff.org>
-+ *
-+ * 12-05-2004 dmarlin: add workaround for Renesas AG-AND chips "disturb" issue.
-+ * Basically, any block not rewritten may lose data when surrounding blocks
-+ * are rewritten many times. JFFS2 ensures this doesn't happen for blocks
-+ * it uses, but the Bad Block Table(s) may not be rewritten. To ensure they
-+ * do not lose data, force them to be rewritten when some of the surrounding
-+ * blocks are erased. Rather than tracking a specific nearby block (which
-+ * could itself go bad), use a page address 'mask' to select several blocks
-+ * in the same area, and rewrite the BBT when any of them are erased.
-+ *
-+ * 01-03-2005 dmarlin: added support for the device recovery command sequence for Renesas
-+ * AG-AND chips. If there was a sudden loss of power during an erase operation,
-+ * a "device recovery" operation must be performed when power is restored
-+ * to ensure correct operation.
-+ *
-+ * 01-20-2005 dmarlin: added support for optional hardware specific callback routine to
-+ * perform extra error status checks on erase and write failures. This required
-+ * adding a wrapper function for nand_read_ecc.
-+ *
-+ * 08-20-2005 vwool: suspend/resume added
-+ *
-+ * Credits:
-+ * David Woodhouse for adding multichip support
-+ *
-+ * Aleph One Ltd. and Toby Churchill Ltd. for supporting the
-+ * rework for 2K page size chips
-+ *
-+ * TODO:
-+ * Enable cached programming for 2k page size chips
-+ * Check, if mtd->ecctype should be set to MTD_ECC_HW
-+ * if we have HW ecc support.
-+ * The AG-AND chips have nice features for speed improvement,
-+ * which are not supported yet. Read / program 4 pages in one go.

-+ *
-+ * Description:
-+ *
-+ * When nand_scan_bbt is called, then it tries to find the bad block table
-+ * depending on the options in the bbt descriptor(s). If a bbt is found
-+ * then the contents are read and the memory based bbt is created. If a
-+ * mirrored bbt is selected then the mirror is searched too and the
-+ * versions are compared. If the mirror has a greater version number
-+ * than the mirror bbt is used to build the memory based bbt.
-+ * If the tables are not versioned, then we "or" the bad block information.
-+ * If one of the bbt's is out of date or does not exist it is (re)created.
-+ * If no bbt exists at all then the device is scanned for factory marked
-+ * good / bad blocks and the bad block tables are created.
-+ *
-+ * For manufacturer created bbts like the one found on M-SYS DOC devices
-+ * the bbt is searched and read but never created
-+ *
-+ * The autogenerated bad block table is located in the last good blocks
-+ * of the device. The table is mirrored, so it can be updated eventually.
-+ * The table is marked in the oob area with an ident pattern and a version
-+ * number which indicates which of both tables is more up to date.
-+ *
-+ * The table uses 2 bits per block
-+ * 11b: block is good
-+ * 00b: block is factory marked bad
-+ * 01b, 10b: block is marked bad due to wear
-+ *
-+ * The memory bad block table uses the following scheme:
-+ * 00b: block is good
-+ * 01b: block is marked bad due to wear
-+ * 10b: block is reserved (to protect the bbt area)
-+ * 11b: block is factory marked bad
-+ *
-+ * Multichip devices like DOC store the bad block info per floor.
-+ *
-+ * Following assumptions are made:
-+ * - bbts start at a page boundary, if autolocated on a block boundary
-+ * - the space neccecary for a bbt in FLASH does not exceed a block boundary

-- * Fixed typo.
-- *
-- * Revision 1.3 2003/06/02 12:51:27 johana
-- * Now compiles.
-- * Commented some include files that probably can be removed.
-- *
-- * Revision 1.2 2003/06/02 12:09:41 johana
-- * Ported to ETRAX FS using the trig interrupt instead of timer1.
-- *
-- * Revision 1.3 2002/12/12 08:26:32 starvik
-- * Don't use C-comments inside CVS comments

-- * Fast timers (from Linux 2.4)
-- *
-- * Revision 1.5 2002/10/15 06:21:39 starvik
-- * Added call to init_waitqueue_head
-- *
-- * Revision 1.4 2002/05/28 17:47:59 johana
-- * Added del_fast_timer()
-- *
-- * Revision 1.3 2002/05/28 16:16:07 johana
-- * Handle empty fast_timer_list
-- *
-- * Revision 1.2 2002/05/27 15:38:42 johana

-- * (includes, wait_queue, PROC_FS and snprintf)
-- *
-- * Revision 1.1 2002/05/27 15:32:25 johana
-- * arch/etrax100/kernel/fasttimer.c v1.8 from the elinux tree.
-- *
-- * Revision 1.8 2001/11/27 13:50:40 pkj
-- * Disable interrupts while stopping the timer and while modifying the
-- * list of active timers in timer1_handler() as it may be interrupted
-- * by other interrupts (e.g., the serial interrupt) which may add fast
-- * timers.
-- *
-- * Revision 1.7 2001/11/22 11:50:32 pkj
-- * * Only store information about the last 16 timers.
-- * * proc_fasttimer_read() now uses an allocated buffer, since it
-- * requires more space than just a page even for only writing the
-- * last 16 timers. The buffer is only allocated on request, so
-- * unless /proc/fasttimer is read, it is never allocated.
-- * * Renamed fast_timer_started to fast_timers_started to match
-- * fast_timers_added and fast_timers_expired.
-- * * Some clean-up.
-- *
-- * Revision 1.6 2000/12/13 14:02:08 johana
-- * Removed volatile for fast_timer_list
-- *
-- * Revision 1.5 2000/12/13 13:55:35 johana
-- * Added DEBUG_LOG, added som cli() and cleanup
-- *
-- * Revision 1.4 2000/12/05 13:48:50 johana
-- * Added range check when writing proc file, modified timer int handling
-- *
-- * Revision 1.3 2000/11/23 10:10:20 johana
-- * More debug/logging possibilities.
-- * Moved GET_JIFFIES_USEC() to timex.h and time.c
-- *
-- * Revision 1.2 2000/11/01 13:41:04 johana
-- * Clean up and bugfixes.
-- * Created new do_gettimeofday_fast() that gets a timeval struct
-- * with time based on jiffies and *R_TIMER0_DATA, uses a table
-- * for fast conversion of timer value to microseconds.
-- * (Much faster the standard do_gettimeofday() and we don't really
-- * wan't to use the true time - we wan't the "uptime" so timers don't screw up
-- * when we change the time.
-- * TODO: Add efficient support for continuous timers as well.
-- *
-- * Revision 1.1 2000/10/26 15:49:16 johana
-- * Added fasttimer, highresolution timers.

-+ * On ETRAX FS, an interrupt remains latched and active until ack:ed.
-+ * Further, ATA acks are without effect as long as INTRQ is asserted, as the
-+ * corresponding ATA interrupt is continuously set to active. There will be a
-+ * clearing ack at the usual cris_ide_ack_intr call, but that serves just to
-+ * gracefully handle an actual spurious interrupt or similar situation (which
-+ * will cause an early return without further actions, see the ide_intr
-+ * function).
-+ *
-+ * However, the normal case at time of this writing is that nothing has
-+ * changed from when INTRQ was asserted until the cris_ide_ack_intr call; no
-+ * ATA registers written and no status register read, so INTRQ will *remain*
-+ * asserted, thus *another* interrupt will be latched, and will be seen as a
-+ * spurious interrupt after the "real" interrupt is serviced. With lots of
-+ * ATA traffic (as in a trivial file-copy between two drives), this will trig
-+ * the condition desc->irqs_unhandled > 99900 in
-+ * kernel/irq/spurious.c:note_interrupt and the system will halt.
-+ *
-+ * To actually get rid of the interrupt corresponding to the current INTRQ
-+ * assertion, we make a second ack after the next ATA register read or write;
-+ * i.e. when INTRQ must be deasserted. At that time, we don't have the hwif
-+ * pointer available, so we need to stash a local copy (safe, because it'll be
-+ * set and cleared within the same spin_lock_irqsave region). The pointer
-+ * serves doubly as a boolean flag that an ack is needed. The caller must
-+ * NULL the pointer after the "second ack".

-+ * Regarding RS485 operation in crisv32 serial driver.
-+ * ---------------------------------------------------
-+ * RS485 can be run in two modes, full duplex using four wires (485FD) and
-+ * half duplex using two wires (485HD). The default mode of each serial port
-+ * is configured in the kernel configuration. The available modes are:
-+ * RS-232, RS-485 half duplex, and RS-485 full duplex.
-+ *
-+ * In the 485HD mode the direction of the data bus must be able to switch.
-+ * The direction of the transceiver is controlled by the RTS signal. Hence
-+ * the auto_rts function in the ETRAX FS chip is enabled in this mode, which
-+ * automatically toggle RTS when transmitting. The initial direction of the
-+ * port is receiving.
-+ *
-+ * In the 485FD mode two transceivers will be used, one in each direction.
-+ * Usually the hardware can handle both 485HD and 485FD, which implies that
-+ * one of the transceivers can change direction. Consequently that transceiver
-+ * must be tied to operate in the opposite direction of the other one, setting
-+ * and keeping RTS to a fixed value do this.
-+ *
-+ * There are two special "ioctl" that can configure the ports. These two are
-+ * left for backward compatible with older applications. The effects of using
-+ * them are described below:
-+ * The TIOCSERSETRS485:
-+ * This ioctl sets a serial port in 232 mode to 485HD mode or vise versa. The
-+ * state of the port is kept when closing the port. Note that this ioctl has no
-+ * effect on a serial port in the 485FD mode.
-+ * The TIOCSERWRRS485:
-+ * This ioctl set a serial port in 232 mode to 485HD mode and writes the data
-+ * "included" in the ioctl to the port. The port will then stay in 485HD mode.
-+ * Using this ioctl on a serial port in the 485HD mode will transmit the data
-+ * without changing the mode. Using this ioctl on a serial port in 485FD mode
-+ * will not change the mode and simply send the data using the 485FD mode.

-- to guarantee that control traffic gets 10% of the bandwidth, and periodic transfer may
-- allocate the rest (90%). This doesn't work though. Read on for a lenghty explanation.
--
-- While there is a difference between rev. 2 and rev. 3 of the ETRAX 100LX regarding the NAK
-- behaviour, it doesn't solve this problem. What happens is that a control transfer will not
-- be interrupted in its data stage when PSTART happens (the point at which periodic traffic
-- is started). Thus, if PSTART is set to 10800 and its IN or OUT token is NAKed until just before
-- PSTART happens, it will continue the IN/OUT transfer as long as it's ACKed. After it's done,
-- there may be too little time left for an isochronous transfer, causing an epid attention
-- interrupt due to perror. The work-around for this is to let the control transfers run at the
-- end of the frame instead of at the beginning, and will be interrupted just fine if it doesn't
-- fit into the frame. However, since there will *always* be a control transfer at the beginning
-- of the frame, regardless of what we set PSTART to, that transfer might be a 64-byte transfer
-- which consumes up to 15% of the frame, leaving only 85% for periodic traffic. The solution to
-- this would be to 'dummy allocate' 5% of the frame with the usb_claim_bandwidth function to make
-- sure that the periodic transfers that are inserted will always fit in the frame.
--
-- The idea was suggested that a control transfer could be split up into several 8 byte transfers,
-- so that it would be interrupted by PSTART, but since this can't be done for an IN transfer this
-- hasn't been implemented.
--
-- The value 11960 is chosen to be just after the SOF token, with a couple of bit times extra
-- for possible bit stuffing. */
