--*! function comment).
--*!
--*! Revision 1.3  2001/03/26 16:03:06  bjornw
--*! Needs linux/config.h

--*!
--*! Revision 1.6  1999/10/27 13:19:47  bjornw
--*! Added update_xtime_from_cmos which reads back the updated RTC into the kernel.
--*! /dev/rtc calls it now.
--*!
--*! 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

-+*!                                 instead of ack.
-+*!                                 i2c_getack changed data level while clock
-+*!                                 was high, causing DS75 to see  a stop condition
-+*!

-- * Don't use C-comments inside CVS comments
-- *
-- * Revision 1.2  2002/12/11 15:42:02  starvik
-- * Extracted v10 (ETRAX 100LX) specific stuff from arch/cris/kernel/
-- *
-- * Revision 1.1  2002/11/18 07:58:06  starvik
-- * 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
-- * 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
-- *
-- * 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.

-+ *
-+ *  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

-+ * 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,

-+ *
-+ * 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

-- *
-- * 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

-- * Revision 1.1  2002/11/18 07:58:06  starvik
-- * 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
-- * 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
-- *
-- * 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. */
