-/*
-   This is the AT91 MCI driver that has been tested with both MMC cards
-   and SD-cards.  Boards that support write protect are now supported.
-   The CCAT91SBC001 board does not support SD cards.
-
-   The three entry points are at91_mci_request, at91_mci_set_ios
-   and at91_mci_get_ro.
-
-   SET IOS
-     This configures the device to put it into the correct mode and clock speed
-     required.
-
-   MCI REQUEST
-     MCI request processes the commands sent in the mmc_request structure. This
-     can consist of a processing command and a stop command in the case of
-     multiple block transfers.
-
-     There are three main types of request, commands, reads and writes.
-
-     Commands are straight forward. The command is submitted to the controller and
-     the request function returns. When the controller generates an interrupt to indicate
-     the command is finished, the response to the command are read and the mmc_request_done
-     function called to end the request.
-
-     Reads and writes work in a similar manner to normal commands but involve the PDC (DMA)
-     controller to manage the transfers.
-
-     A read is done from the controller directly to the scatterlist passed in from the request.
-     Due to a bug in the AT91RM9200 controller, when a read is completed, all the words are byte
-     swapped in the scatterlist buffers.  AT91SAM926x are not affected by this bug.
-
-     The sequence of read interrupts is: ENDRX, RXBUFF, CMDRDY
-
-     A write is slightly different in that the bytes to write are read from the scatterlist
-     into a dma memory buffer (this is in case the source buffer should be read only). The
-     entire write buffer is then done from this single dma memory buffer.
-
-     The sequence of write interrupts is: ENDTX, TXBUFE, NOTBUSY, CMDRDY
-
-   GET RO
-     Gets the status of the write protect pin, if available.

  * Notes on locking strategy:
  *
- * Most CSRs are 128-bit (oword) and therefore cannot be read or
- * written atomically.  Access from the host is buffered by the Bus
- * Interface Unit (BIU).  Whenever the host reads from the lowest
- * address of such a register, or from the address of a different such
- * register, the BIU latches the register's value.  Subsequent reads
- * from higher addresses of the same register will read the latched
- * value.  Whenever the host writes part of such a register, the BIU
- * collects the written value and does not write to the underlying
- * register until all 4 dwords have been written.  A similar buffering
- * scheme applies to host access to the NIC's 64-bit SRAM.
+ * Many CSRs are very wide and cannot be read or written atomically.
+ * Writes from the host are buffered by the Bus Interface Unit (BIU)
+ * up to 128 bits.  Whenever the host writes part of such a register,
+ * the BIU collects the written value and does not write to the
+ * underlying register until all 4 dwords have been written.  A
+ * similar buffering scheme applies to host access to the NIC's 64-bit
+ * SRAM.
  *
- * Access to different CSRs and 64-bit SRAM words must be serialised,
- * since interleaved access can result in lost writes or lost
- * information from read-to-clear fields.  We use efx_nic::biu_lock
- * for this.  (We could use separate locks for read and write, but

+ * A Tx or Rx queue resides in host DRAM, and is comprised of a circular buffer
+ * of buffer descriptors, each of which points to one or more data buffers for
+ * the device to read from or fill.  Driver and device exchange status of each
+ * queue via "read" and "write" pointers.  Driver keeps minimum of 2 empty
+ * entries in each circular buffer, to protect against confusing empty and full
+ * queue states.
+ *
+ * The device reads or writes the data in the queues via the device's several
+ * DMA/FIFO channels.  Each queue is mapped to a single DMA channel.
+ *
+ * For Tx queue, there are low mark and high mark limits. If, after queuing
+ * the packet for Tx, free space become < low mark, Tx queue stopped. When
+ * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
+ * Tx queue resumed.

-/*************** DMA-QUEUE-GENERAL-FUNCTIONS  *****
- * DMA services
- *
- * Theory of operation
- *
- * A Tx or Rx queue resides in host DRAM, and is comprised of a circular buffer
- * of buffer descriptors, each of which points to one or more data buffers for
- * the device to read from or fill.  Driver and device exchange status of each
- * queue via "read" and "write" pointers.  Driver keeps minimum of 2 empty
- * entries in each circular buffer, to protect against confusing empty and full
- * queue states.
- *
- * The device reads or writes the data in the queues via the device's several
- * DMA/FIFO channels.  Each queue is mapped to a single DMA channel.
- *
- * For Tx queue, there are low mark and high mark limits. If, after queuing
- * the packet for Tx, free space become < low mark, Tx queue stopped. When
- * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
- * Tx queue resumed.

-Each PPI is a 8255 chip providing 24 DIO channels.  The DIO channels
-are configurable as inputs or outputs in four groups:
-
-  Port A  - channels  0 to  7
-  Port B  - channels  8 to 15
-  Port CL - channels 16 to 19
-  Port CH - channels 20 to 23
-
-Only mode 0 of the 8255 chips is supported.
-
-Each CTR is a 8254 chip providing 3 16-bit counter channels.  Each
-channel is configured individually with INSN_CONFIG instructions.  The
-specific type of configuration instruction is specified in data[0].
-Some configuration instructions expect an additional parameter in
-data[1]; others return a value in data[1].  The following configuration
-instructions are supported:
-
-  INSN_CONFIG_SET_COUNTER_MODE.  Sets the counter channel's mode and
-    BCD/binary setting specified in data[1].
-
-  INSN_CONFIG_8254_READ_STATUS.  Reads the status register value for the
-    counter channel into data[1].
-
-  INSN_CONFIG_SET_CLOCK_SRC.  Sets the counter channel's clock source as
-    specified in data[1] (this is a hardware-specific value).  Not
-    supported on PC214E.  For the other boards, valid clock sources are
-    0 to 7 as follows:
-
-      0.  CLK n, the counter channel's dedicated CLK input from the SK1
-	connector.  (N.B. for other values, the counter channel's CLKn
-	pin on the SK1 connector is an output!)
-      1.  Internal 10 MHz clock.
-      2.  Internal 1 MHz clock.
-      3.  Internal 100 kHz clock.
-      4.  Internal 10 kHz clock.
-      5.  Internal 1 kHz clock.
-      6.  OUT n-1, the output of counter channel n-1 (see note 1 below).
-      7.  Ext Clock, the counter chip's dedicated Ext Clock input from
-	the SK1 connector.  This pin is shared by all three counter
-	channels on the chip.
-
-  INSN_CONFIG_GET_CLOCK_SRC.  Returns the counter channel's current
-    clock source in data[1].  For internal clock sources, data[2] is set
-    to the period in ns.
-
-  INSN_CONFIG_SET_GATE_SRC.  Sets the counter channel's gate source as
-    specified in data[2] (this is a hardware-specific value).  Not
-    supported on PC214E.  For the other boards, valid gate sources are 0
-    to 7 as follows:
-
-      0.  VCC (internal +5V d.c.), i.e. gate permanently enabled.
-      1.  GND (internal 0V d.c.), i.e. gate permanently disabled.
-      2.  GAT n, the counter channel's dedicated GAT input from the SK1
-	connector.  (N.B. for other values, the counter channel's GATn
-	pin on the SK1 connector is an output!)
-      3.  /OUT n-2, the inverted output of counter channel n-2 (see note
-	2 below).
-      4.  Reserved.
-      5.  Reserved.
-      6.  Reserved.
-      7.  Reserved.
-
-  INSN_CONFIG_GET_GATE_SRC.  Returns the counter channel's current gate
-    source in data[2].
-
-Clock and gate interconnection notes:
-
-  1.  Clock source OUT n-1 is the output of the preceding channel on the
-  same counter subdevice if n > 0, or the output of channel 2 on the
-  preceding counter subdevice (see note 3) if n = 0.
-
-  2.  Gate source /OUT n-2 is the inverted output of channel 0 on the
-  same counter subdevice if n = 2, or the inverted output of channel n+1

-  3.  The counter subdevices are connected in a ring, so the highest
-  counter subdevice precedes the lowest.
-
-The 'INTERRUPT' subdevice pretends to be a digital input subdevice.  The
-digital inputs come from the interrupt status register.  The number of
-channels matches the number of interrupt sources.  The PC214E does not
-have an interrupt status register; see notes on 'INTERRUPT SOURCES'

-When an interrupt source is enabled in the interrupt source enable
-register, a rising edge on the source signal latches the corresponding
-bit to 1 in the interrupt status register.
-
-When the interrupt status register value as a whole (actually, just the
-6 least significant bits) goes from zero to non-zero, the board will
-generate an interrupt.  For level-triggered hardware interrupts (PCI
-card), the interrupt will remain asserted until the interrupt status
-register is cleared to zero.  For edge-triggered hardware interrupts
-(ISA card), no further interrupts will occur until the interrupt status
-register is cleared to zero.  To clear a bit to zero in the interrupt
-status register, the corresponding interrupt source must be disabled
-in the interrupt source enable register (there is no separate interrupt
-clear register).
-
-The PC214E does not have an interrupt source enable register or an
-interrupt status register; its 'INTERRUPT' subdevice has a single
-channel and its interrupt source is selected by the position of jumper
-J5.
-
-COMMANDS
-
-The driver supports a read streaming acquisition command on the
-'INTERRUPT' subdevice.  The channel list selects the interrupt sources
-to be enabled.  All channels will be sampled together (convert_src ==
-TRIG_NOW).  The scan begins a short time after the hardware interrupt
-occurs, subject to interrupt latencies (scan_begin_src == TRIG_EXT,
-scan_begin_arg == 0).  The value read from the interrupt status register
-is packed into a short value, one bit per requested channel, in the
-order they appear in the channel list.

+ * Each PPI is a 8255 chip providing 24 DIO channels.  The DIO channels
+ * are configurable as inputs or outputs in four groups:
+ *
+ *   Port A  - channels  0 to  7
+ *   Port B  - channels  8 to 15
+ *   Port CL - channels 16 to 19
+ *   Port CH - channels 20 to 23
+ *
+ * Only mode 0 of the 8255 chips is supported.
+ *
+ * Each CTR is a 8254 chip providing 3 16-bit counter channels.  Each
+ * channel is configured individually with INSN_CONFIG instructions.  The
+ * specific type of configuration instruction is specified in data[0].
+ * Some configuration instructions expect an additional parameter in
+ * data[1]; others return a value in data[1].  The following configuration
+ * instructions are supported:
+ *
+ *   INSN_CONFIG_SET_COUNTER_MODE.  Sets the counter channel's mode and
+ *     BCD/binary setting specified in data[1].
+ *
+ *   INSN_CONFIG_8254_READ_STATUS.  Reads the status register value for the
+ *     counter channel into data[1].
+ *
+ *   INSN_CONFIG_SET_CLOCK_SRC.  Sets the counter channel's clock source as
+ *     specified in data[1] (this is a hardware-specific value).  Not
+ *     supported on PC214E.  For the other boards, valid clock sources are
+ *     0 to 7 as follows:
+ *
+ *       0.  CLK n, the counter channel's dedicated CLK input from the SK1
+ *         connector.  (N.B. for other values, the counter channel's CLKn
+ *         pin on the SK1 connector is an output!)
+ *       1.  Internal 10 MHz clock.
+ *       2.  Internal 1 MHz clock.
+ *       3.  Internal 100 kHz clock.
+ *       4.  Internal 10 kHz clock.
+ *       5.  Internal 1 kHz clock.
+ *       6.  OUT n-1, the output of counter channel n-1 (see note 1 below).
+ *       7.  Ext Clock, the counter chip's dedicated Ext Clock input from
+ *         the SK1 connector.  This pin is shared by all three counter
+ *         channels on the chip.
+ *
+ *     For the PCIe boards, clock sources in the range 0 to 31 are allowed
+ *     and the following additional clock sources are defined:
+ *
+ *       8.  HIGH logic level.
+ *       9.  LOW logic level.
+ *      10.  "Pattern present" signal.
+ *      11.  Internal 20 MHz clock.
+ *
+ *   INSN_CONFIG_GET_CLOCK_SRC.  Returns the counter channel's current
+ *     clock source in data[1].  For internal clock sources, data[2] is set
+ *     to the period in ns.
+ *
+ *   INSN_CONFIG_SET_GATE_SRC.  Sets the counter channel's gate source as
+ *     specified in data[2] (this is a hardware-specific value).  Not
+ *     supported on PC214E.  For the other boards, valid gate sources are 0
+ *     to 7 as follows:
+ *
+ *       0.  VCC (internal +5V d.c.), i.e. gate permanently enabled.
+ *       1.  GND (internal 0V d.c.), i.e. gate permanently disabled.
+ *       2.  GAT n, the counter channel's dedicated GAT input from the SK1
+ *         connector.  (N.B. for other values, the counter channel's GATn
+ *         pin on the SK1 connector is an output!)
+ *       3.  /OUT n-2, the inverted output of counter channel n-2 (see note
+ *         2 below).
+ *       4.  Reserved.
+ *       5.  Reserved.
+ *       6.  Reserved.
+ *       7.  Reserved.
+ *
+ *     For the PCIe boards, gate sources in the range 0 to 31 are allowed;
+ *     the following additional clock sources and clock sources 6 and 7 are
+ *     (re)defined:
+ *
+ *       6.  /GAT n, negated version of the counter channel's dedicated
+ *         GAT input (negated version of gate source 2).
+ *       7.  OUT n-2, the non-inverted output of counter channel n-2
+ *         (negated version of gate source 3).
+ *       8.  "Pattern present" signal, HIGH while pattern present.
+ *       9.  "Pattern occurred" latched signal, latches HIGH when pattern
+ *         occurs.
+ *      10.  "Pattern gone away" latched signal, latches LOW when pattern
+ *         goes away after it occurred.
+ *      11.  Negated "pattern present" signal, LOW while pattern present
+ *         (negated version of gate source 8).
+ *      12.  Negated "pattern occurred" latched signal, latches LOW when
+ *         pattern occurs (negated version of gate source 9).
+ *      13.  Negated "pattern gone away" latched signal, latches LOW when
+ *         pattern goes away after it occurred (negated version of gate
+ *         source 10).
+ *
+ *   INSN_CONFIG_GET_GATE_SRC.  Returns the counter channel's current gate
+ *     source in data[2].
+ *
+ * Clock and gate interconnection notes:
+ *
+ *   1.  Clock source OUT n-1 is the output of the preceding channel on the
+ *   same counter subdevice if n > 0, or the output of channel 2 on the
+ *   preceding counter subdevice (see note 3) if n = 0.
+ *
+ *   2.  Gate source /OUT n-2 is the inverted output of channel 0 on the
+ *   same counter subdevice if n = 2, or the inverted output of channel n+1
+ *   on the preceding counter subdevice (see note 3) if n < 2.
+ *
+ *   3.  The counter subdevices are connected in a ring, so the highest
+ *   counter subdevice precedes the lowest.
+ *
+ * The 'TIMER' subdevice is a free-running 32-bit timer subdevice.
+ *
+ * The 'INTERRUPT' subdevice pretends to be a digital input subdevice.  The
+ * digital inputs come from the interrupt status register.  The number of
+ * channels matches the number of interrupt sources.  The PC214E does not
+ * have an interrupt status register; see notes on 'INTERRUPT SOURCES'
+ * below.

-    NAME
-        CsrLogLevelTextSet
-
-    DESCRIPTION
-        Set the text logging level for a given origin and optionally sub origin
-        by name. If either string is NULL or zero length, it is interpreted as
-        all origins and/or all sub origins respectively. If originName is NULL
-        or zero length, subOriginName is ignored.
-
-        Passing NULL or zero length strings in both originName and subOriginName
-        is equivalent to calling CsrLogLevelTextSetAll, and overrides all
-        previous filter configurations for all origins and sub origins.
-
-        Passing NULL or a zero length string in subOriginName overrides all
-        previous filter configurations for all sub origins of the specified
-        origin.
-
-        Note: the supplied strings may be accessed after the function returns
-        and must remain valid and constant until CsrLogDeinit is called.
-
-        Note: when specifying an origin (originName is not NULL and not zero
-        length), this function can only be used for origins that use the
-        csr_log_text_2.h interface for registration and logging. Filtering for
-        origins that use the legacy csr_log_text.h interface must be be
-        configured using the legacy filter configuration functions that accept
-        a CsrLogTextTaskId as origin specifier. However, when not specifying an
-        origin this function also affects origins that have been registered with
-        the legacy csr_log_text.h interface. Furthermore, using this function
-        and the legacy filter configuration functions on the same origin is not
-        allowed.
-
-    PARAMETERS
-        originName - a string containing the name of the origin. Can be NULL or
-            zero length to set the log level for all origins. In this case, the
-            subOriginName parameter will be ignored.
-        subOriginName - a string containing the name of the sub origin. Can be
-            NULL or zero length to set the log level for all sub origins of the
-            specified origin.
-        warningLevelMask - The desired log level for the specified origin(s) and
-            sub origin(s).

+TODOs
+-----
+1. Implement retries for RCODE_BUSY, RCODE_NO_ACK and RCODE_SEND_ERROR
+   - I/O is handled asynchronously which presents some issues when error
+     conditions occur.
+2. Implement _robust_ console on top of this. The existing prototype console
+   driver is not ready for the big leagues yet.
+3. Expose means of controlling attach/detach of peers via sysfs. Include
+   GUID-to-port matching/whitelist/blacklist.
+
+-- Issues with firewire stack --
+1. This driver uses the same unregistered vendor id that the firewire core does
+     (0xd00d1e). Perhaps this could be exposed as a define in
+     firewire-constants.h?
+2. MAX_ASYNC_PAYLOAD needs to be publicly exposed by core/ohci
+   - otherwise how will this driver know the max size of address window to
+     open for one packet write?
+3. Maybe device_max_receive() and link_speed_to_max_payload() should be
+     taken up by the firewire core?
+4. To avoid dropping rx data while still limiting the maximum buffering,
+     the size of the AR context must be known. How to expose this to drivers?
+5. Explore if bigger AR context will reduce RCODE_BUSY responses
+   (or auto-grow to certain max size -- but this would require major surgery
+    as the current AR is contiguously mapped)
+
+-- Issues with TTY core --
+  1. Hack for alternate device name scheme
+     - because udev no longer allows device renaming, devices should have
+       their proper names on creation. This is an issue for creating the
+       fwloop<n> device with the fwtty<n> devices because although duplicating
+       roughly the same operations as tty_port_register_device() isn't difficult,
+       access to the tty_class & tty_fops is restricted in scope.
+
+       This is currently being worked around in create_loop_device() by
+       extracting the tty_class ptr and tty_fops ptr from the previously created
+       tty devices. Perhaps an add'l api can be added -- eg.,
+       tty_{port_}register_named_device().

+/**
+ * The design basis for the DMA FIFO is to provide an output side that
+ * complies with the streaming DMA API design that can be DMA'd from directly
+ * (without additional copying), coupled with an input side that maintains a
+ * logically consistent 'apparent' size (ie, bytes in + bytes avail is static
+ * for the lifetime of the FIFO).
+ *
+ * DMA output transactions originate on a cache line boundary and can be
+ * variably-sized. DMA output transactions can be retired out-of-order but
+ * the FIFO will only advance the output in the original input sequence.
+ * This means the FIFO will eventually stall if a transaction is never retired.
+ *
+ * Chunking the output side into cache line multiples means that some FIFO
+ * memory is unused. For example, if all the avail input has been pended out,
+ * then the in and out markers are re-aligned to the next cache line.
+ * The maximum possible waste is
+ *     (cache line alignment - 1) * (max outstanding dma transactions)
+ * This potential waste requires additional hidden capacity within the FIFO
+ * to be able to accept input while the 'apparent' size has not been reached.
+ *
+ * Additional cache lines (ie, guard area) are used to minimize DMA
+ * fragmentation when wrapping at the end of the FIFO. Input is allowed into the
+ * guard area, but the in and out FIFO markers are wrapped when DMA is pended.

+ *   'serial' unit specifier id
+ * - adding a unit directory to the config ROM(s) for a 'serial' unit
+ *
+ * The firewire core registers unit devices by enumerating unit directories
+ * of a node's config ROM after reading the config ROM when a new node is
+ * added to the bus topology after a bus reset.
+ *
+ * The practical implications of this are:
+ * - this probe is called for both local and remote nodes that have a 'serial'
+ *   unit directory in their config ROM (that matches the specifiers in
+ *   fwserial_id_table).
+ * - no specific order is enforced for local vs. remote unit devices
+ *
+ * This unit driver copes with the lack of specific order in the same way the
+ * firewire net driver does -- each probe, for either a local or remote unit
+ * device, is treated as a 'peer' (has a struct fwtty_peer instance) and the
+ * first peer created for a given fw_card (tracked by the global fwserial_list)
+ * creates the underlying TTYs (aggregated in a fw_serial instance).
+ *
+ * NB: an early attempt to differentiate local & remote unit devices by creating
+ *     peers only for remote units and fw_serial instances (with their
+ *     associated TTY devices) only for local units was discarded. Managing
+ *     the peer lifetimes on device removal proved too complicated.
+ *
+ * fwserial_probe/fwserial_remove are effectively serialized by the
+ * fwserial_list_mutex. This is necessary because the addition of the first peer
+ * for a given fw_card will trigger the creation of the fw_serial for that
+ * fw_card, which must not simultaneously contend with the removal of the

+ * which
+ *   -checks-if-tty-buffer-has-char-to-send
+ *   -writes-data-to-uart
+ *   -enable-tx-intr
+ *
+ * Once data bits are pushed out, controller raises the Tx-room-avail-Interrupt.
+ * The first thing Tx ISR does is disable further Tx interrupts (as this could
+ * be the last char to send, before settling down into the quiet polled mode).
+ * It then calls the exact routine used by tty layer write to send out any
+ * more char in tty buffer. In case of sending, it re-enables Tx-intr. In case
+ * of no data, it remains disabled.

- * The File-backed Storage Gadget acts as a USB Mass Storage device,
- * appearing to the host as a disk drive or as a CD-ROM drive.  In addition
- * to providing an example of a genuinely useful gadget driver for a USB
- * device, it also illustrates a technique of double-buffering for increased
- * throughput.  Last but not least, it gives an easy way to probe the
- * behavior of the Mass Storage drivers in a USB host.
- *
- * Backing storage is provided by a regular file or a block device, specified
- * by the "file" module parameter.  Access can be limited to read-only by
- * setting the optional "ro" module parameter.  (For CD-ROM emulation,
- * access is always read-only.)  The gadget will indicate that it has
- * removable media if the optional "removable" module parameter is set.
- *
- * The gadget supports the Control-Bulk (CB), Control-Bulk-Interrupt (CBI),
- * and Bulk-Only (also known as Bulk-Bulk-Bulk or BBB) transports, selected
- * by the optional "transport" module parameter.  It also supports the
- * following protocols: RBC (0x01), ATAPI or SFF-8020i (0x02), QIC-157 (0c03),
- * UFI (0x04), SFF-8070i (0x05), and transparent SCSI (0x06), selected by
- * the optional "protocol" module parameter.  In addition, the default
- * Vendor ID, Product ID, release number and serial number can be overridden.
- *
- * There is support for multiple logical units (LUNs), each of which has
- * its own backing file.  The number of LUNs can be set using the optional
- * "luns" module parameter (anywhere from 1 to 8), and the corresponding
- * files are specified using comma-separated lists for "file" and "ro".
- * The default number of LUNs is taken from the number of "file" elements;
- * it is 1 if "file" is not given.  If "removable" is not set then a backing
- * file must be specified for each LUN.  If it is set, then an unspecified
- * or empty backing filename means the LUN's medium is not loaded.  Ideally
- * each LUN would be settable independently as a disk drive or a CD-ROM
- * drive, but currently all LUNs have to be the same type.  The CD-ROM
- * emulation includes a single data track and no audio tracks; hence there
- * need be only one backing file per LUN.
- *
- * Requirements are modest; only a bulk-in and a bulk-out endpoint are
- * needed (an interrupt-out endpoint is also needed for CBI).  The memory
- * requirement amounts to two 16K buffers, size configurable by a parameter.
- * Support is included for both full-speed and high-speed operation.
- *
- * Note that the driver is slightly non-portable in that it assumes a
- * single memory/DMA buffer will be useable for bulk-in, bulk-out, and
- * interrupt-in endpoints.  With most device controllers this isn't an
- * issue, but there may be some with hardware restrictions that prevent
- * a buffer from being used by more than one endpoint.
- *
- * Module options:
- *
- *	file=filename[,filename...]
- *				Required if "removable" is not set, names of
- *					the files or block devices used for
- *					backing storage
- *	serial=HHHH...		Required serial number (string of hex chars)
- *	ro=b[,b...]		Default false, booleans for read-only access
- *	removable		Default false, boolean for removable media
- *	luns=N			Default N = number of filenames, number of
- *					LUNs to support
- *	nofua=b[,b...]		Default false, booleans for ignore FUA flag
- *					in SCSI WRITE(10,12) commands
- *	stall			Default determined according to the type of
- *					USB device controller (usually true),
- *					boolean to permit the driver to halt
- *					bulk endpoints
- *	cdrom			Default false, boolean for whether to emulate
- *					a CD-ROM drive
- *	transport=XXX		Default BBB, transport name (CB, CBI, or BBB)
- *	protocol=YYY		Default SCSI, protocol name (RBC, 8020 or
- *					ATAPI, QIC, UFI, 8070, or SCSI;
- *					also 1 - 6)
- *	vendor=0xVVVV		Default 0x0525 (NetChip), USB Vendor ID
- *	product=0xPPPP		Default 0xa4a5 (FSG), USB Product ID
- *	release=0xRRRR		Override the USB release number (bcdDevice)
- *	buflen=N		Default N=16384, buffer size used (will be
- *					rounded down to a multiple of
- *					PAGE_CACHE_SIZE)
- *
- * If CONFIG_USB_FILE_STORAGE_TEST is not set, only the "file", "serial", "ro",
- * "removable", "luns", "nofua", "stall", and "cdrom" options are available;
- * default values are used for everything else.
- *
- * The pathnames of the backing files and the ro settings are available in
- * the attribute files "file", "nofua", and "ro" in the lun<n> subdirectory of
- * the gadget's sysfs directory.  If the "removable" option is set, writing to
- * these files will simulate ejecting/loading the medium (writing an empty
- * line means eject) and adjusting a write-enable tab.  Changes to the ro
- * setting are not allowed when the medium is loaded or if CD-ROM emulation
- * is being used.
- *
- * This gadget driver is heavily based on "Gadget Zero" by David Brownell.
- * The driver's SCSI command interface was based on the "Information
- * technology - Small Computer System Interface - 2" document from
- * X3T9.2 Project 375D, Revision 10L, 7-SEP-93, available at
- * <http://www.t10.org/ftp/t10/drafts/s2/s2-r10l.pdf>.  The single exception
- * is opcode 0x23 (READ FORMAT CAPACITIES), which was based on the
- * "Universal Serial Bus Mass Storage Class UFI Command Specification"
- * document, Revision 1.0, December 14, 1998, available at
- * <http://www.usb.org/developers/devclass_docs/usbmass-ufi10.pdf>.

-/*
- *				Driver Design
- *
- * The FSG driver is fairly straightforward.  There is a main kernel
- * thread that handles most of the work.  Interrupt routines field
- * callbacks from the controller driver: bulk- and interrupt-request
- * completion notifications, endpoint-0 events, and disconnect events.
- * Completion events are passed to the main thread by wakeup calls.  Many
- * ep0 requests are handled at interrupt time, but SetInterface,
- * SetConfiguration, and device reset requests are forwarded to the
- * thread in the form of "exceptions" using SIGUSR1 signals (since they
- * should interrupt any ongoing file I/O operations).
- *
- * The thread's main routine implements the standard command/data/status
- * parts of a SCSI interaction.  It and its subroutines are full of tests
- * for pending signals/exceptions -- all this polling is necessary since
- * the kernel has no setjmp/longjmp equivalents.  (Maybe this is an
- * indication that the driver really wants to be running in userspace.)
- * An important point is that so long as the thread is alive it keeps an
- * open reference to the backing file.  This will prevent unmounting
- * the backing file's underlying filesystem and could cause problems
- * during system shutdown, for example.  To prevent such problems, the
- * thread catches INT, TERM, and KILL signals and converts them into
- * an EXIT exception.
- *
- * In normal operation the main thread is started during the gadget's
- * fsg_bind() callback and stopped during fsg_unbind().  But it can also
- * exit when it receives a signal, and there's no point leaving the
- * gadget running when the thread is dead.  So just before the thread
- * exits, it deregisters the gadget driver.  This makes things a little
- * tricky: The driver is deregistered at two places, and the exiting
- * thread can indirectly call fsg_unbind() which in turn can tell the
- * thread to exit.  The first problem is resolved through the use of the
- * REGISTERED atomic bitflag; the driver will only be deregistered once.
- * The second problem is resolved by having fsg_unbind() check
- * fsg->state; it won't try to stop the thread if the state is already
- * FSG_STATE_TERMINATED.
- *
- * To provide maximum throughput, the driver uses a circular pipeline of
- * buffer heads (struct fsg_buffhd).  In principle the pipeline can be
- * arbitrarily long; in practice the benefits don't justify having more
- * than 2 stages (i.e., double buffering).  But it helps to think of the
- * pipeline as being a long one.  Each buffer head contains a bulk-in and
- * a bulk-out request pointer (since the buffer can be used for both
- * output and input -- directions always are given from the host's
- * point of view) as well as a pointer to the buffer and various state
- * variables.
- *
- * Use of the pipeline follows a simple protocol.  There is a variable
- * (fsg->next_buffhd_to_fill) that points to the next buffer head to use.
- * At any time that buffer head may still be in use from an earlier
- * request, so each buffer head has a state variable indicating whether
- * it is EMPTY, FULL, or BUSY.  Typical use involves waiting for the
- * buffer head to be EMPTY, filling the buffer either by file I/O or by
- * USB I/O (during which the buffer head is BUSY), and marking the buffer
- * head FULL when the I/O is complete.  Then the buffer will be emptied
- * (again possibly by USB I/O, during which it is marked BUSY) and
- * finally marked EMPTY again (possibly by a completion routine).
- *
- * A module parameter tells the driver to avoid stalling the bulk
- * endpoints wherever the transport specification allows.  This is
- * necessary for some UDCs like the SuperH, which cannot reliably clear a
- * halt on a bulk endpoint.  However, under certain circumstances the
- * Bulk-only specification requires a stall.  In such cases the driver
- * will halt the endpoint and set a flag indicating that it should clear
- * the halt in software during the next device reset.  Hopefully this
- * will permit everything to work correctly.  Furthermore, although the
- * specification allows the bulk-out endpoint to halt when the host sends
- * too much data, implementing this would cause an unavoidable race.
- * The driver will always use the "no-stall" approach for OUT transfers.
- *
- * One subtle point concerns sending status-stage responses for ep0
- * requests.  Some of these requests, such as device reset, can involve
- * interrupting an ongoing file I/O operation, which might take an
- * arbitrarily long time.  During that delay the host might give up on
- * the original ep0 request and issue a new one.  When that happens the
- * driver should not notify the host about completion of the original
- * request, as the host will no longer be waiting for it.  So the driver
- * assigns to each ep0 request a unique tag, and it keeps track of the
- * tag value of the request associated with a long-running exception
- * (device-reset, interface-change, or configuration-change).  When the
- * exception handler is finished, the status-stage response is submitted
- * only if the current ep0 request tag is equal to the exception request
- * tag.  Thus only the most recently received ep0 request will get a
- * status-stage response.
- *
- * Warning: This driver source file is too long.  It ought to be split up
- * into a header file plus about 3 separate .c files, to handle the details
- * of the Gadget, USB Mass Storage, and SCSI protocols.
