-  3) ATAPI support (Marvell claims the 60xx/70xx chips can do it).
-
-  4) Think about TCQ support here, and for libata in general
-  with controllers that suppport it via host-queuing hardware
-  (a software-only implementation could be a nightmare).
-
-  5) Investigate problems with PCI Message Signalled Interrupts (MSI).
-
-  6) Cache frequently-accessed registers in mv_port_priv to reduce overhead.
-
-  7) Fix/reenable hot plug/unplug (should happen as a side-effect of (2) above).
-
-  8) Develop a low-power-consumption strategy, and implement it.
-
-  9) [Experiment, low priority] See if ATAPI can be supported using
-  "unknown FIS" or "vendor-specific FIS" support, or something creative
-  like that.
-
-  10) [Experiment, low priority] Investigate interrupt coalescing.
-  Quite often, especially with PCI Message Signalled Interrupts (MSI),
-  the overhead reduced by interrupt mitigation is quite often not
-  worth the latency cost.
-
-  11) [Experiment, Marvell value added] Is it possible to use target

- * DIOR is unbuffered while address and data is buffered.
- * This creates two problems:
- * 1. The DIOR pulse is to early (because it is unbuffered)
- * 2. The rise time of DIOR is long
- *
- * There are at least three different plausible solutions
- * 1. Use a pad capable of larger currents in Etrax
- * 2. Use an external buffer
- * 3. Make the strobe pulse longer
- *
- * Some of the strobe timings below are modified to compensate
- * for this. This implies a slight performance decrease.
- *
- * THIS SHOULD NEVER BE CHANGED!

- * TODO: Is this true for the latest LX boards still ?

+ * Windfarm PowerMac thermal control. iMac G5 iSight
+ *
+ * (c) Copyright 2007 Étienne Bersac <bersace@gmail.com>
+ *
+ * Bits & pieces from windfarm_pm81.c by (c) Copyright 2005 Benjamin
+ * Herrenschmidt, IBM Corp. <benh@kernel.crashing.org>
+ *
+ * Released under the term of the GNU GPL v2.
+ *
+ *
+ *
+ * PowerMac12,1
+ * ============
+ *
+ *
+ * The algorithm used is the PID control algorithm, used the same way
+ * the published Darwin code does, using the same values that are
+ * present in the Darwin 8.10 snapshot property lists (note however
+ * that none of the code has been re-used, it's a complete
+ * re-implementation
+ *
+ * There is two models using PowerMac12,1. Model 2 is iMac G5 iSight
+ * 17" while Model 3 is iMac G5 20". They do have both the same
+ * controls with a tiny difference. The control-ids of hard-drive-fan
+ * and cpu-fan is swapped.
+ *
+ *
+ * Target Correction :
+ *
+ * controls have a target correction calculated as :
+ *
+ * new_min = ((((average_power * slope) >> 16) + offset) >> 16) + min_value
+ * new_value = max(new_value, max(new_min, 0))
+ *
+ * OD Fan control correction.
+ *
+ * # model_id: 2
+ *   offset		: -19563152
+ *   slope		:  1956315
+ *
+ * # model_id: 3
+ *   offset		: -15650652
+ *   slope		:  1565065
+ *
+ * HD Fan control correction.
+ *
+ * # model_id: 2
+ *   offset		: -15650652
+ *   slope		:  1565065
+ *
+ * # model_id: 3
+ *   offset		: -19563152
+ *   slope		:  1956315
+ *
+ * CPU Fan control correction.
+ *
+ * # model_id: 2
+ *   offset		: -25431900
+ *   slope		:  2543190
+ *
+ * # model_id: 3
+ *   offset		: -15650652
+ *   slope		:  1565065
+ *
+ *
+ * Target rubber-banding :
+ *
+ * Some controls have a target correction which depends on another
+ * control value. The correction is computed in the following way :
+ *
+ * new_min = ref_value * slope + offset
+ *
+ * ref_value is the value of the reference control. If new_min is
+ * greater than 0, then we correct the target value using :
+ *
+ * new_target = max (new_target, new_min >> 16)
+ *
+ *
+ * # model_id : 2
+ *   control	: cpu-fan
+ *   ref	: optical-drive-fan
+ *   offset	: -15650652
+ *   slope	: 1565065
+ *
+ * # model_id : 3
+ *   control	: optical-drive-fan
+ *   ref	: hard-drive-fan
+ *   offset	: -32768000
+ *   slope	: 65536
+ *
+ *
+ * In order to have the moste efficient correction with those
+ * dependencies, we must trigger HD loop before OD loop before CPU
+ * loop.
+ *
+ *
+ * The various control loops found in Darwin config file are:
+ *
+ * HD Fan control loop.

+ *
+ * The @sqnum is the value of the global sequence counter at the time when this
+ * VID header was created. The global sequence counter is incremented each time
+ * UBI writes a new VID header to the flash, i.e. when it maps a logical
+ * eraseblock to a new physical eraseblock. The global sequence counter is an
+ * unsigned 64-bit integer and we assume it never overflows. The @sqnum
+ * (sequence number) is used to distinguish between older and newer versions of
+ * logical eraseblocks.
+ *
+ * There are 2 situations when there may be more then one physical eraseblock
+ * corresponding to the same logical eraseblock, i.e., having the same @vol_id
+ * and @lnum values in the volume identifier header. Suppose we have a logical
+ * eraseblock L and it is mapped to the physical eraseblock P.
+ *
+ * 1. Because UBI may erase physical eraseblocks asynchronously, the following
+ * situation is possible: L is asynchronously erased, so P is scheduled for
+ * erasure, then L is written to,i.e. mapped to another physical eraseblock P1,
+ * so P1 is written to, then an unclean reboot happens. Result - there are 2
+ * physical eraseblocks P and P1 corresponding to the same logical eraseblock
+ * L. But P1 has greater sequence number, so UBI picks P1 when it attaches the
+ * flash.
+ *
+ * 2. From time to time UBI moves logical eraseblocks to other physical
+ * eraseblocks for wear-leveling reasons. If, for example, UBI moves L from P
+ * to P1, and an unclean reboot happens before P is physically erased, there
+ * are two physical eraseblocks P and P1 corresponding to L and UBI has to
+ * select one of them when the flash is attached. The @sqnum field says which
+ * PEB is the original (obviously P will have lower @sqnum) and the copy. But
+ * it is not enough to select the physical eraseblock with the higher sequence
+ * number, because the unclean reboot could have happen in the middle of the
+ * copying process, so the data in P is corrupted. It is also not enough to
+ * just select the physical eraseblock with lower sequence number, because the
+ * data there may be old (consider a case if more data was added to P1 after
+ * the copying). Moreover, the unclean reboot may happen when the erasure of P
+ * was just started, so it result in unstable P, which is "mostly" OK, but
+ * still has unstable bits.
+ *
+ * UBI uses the @copy_flag field to indicate that this logical eraseblock is a
+ * copy. UBI also calculates data CRC when the data is moved and stores it at
+ * the @data_crc field of the copy (P1). So when UBI needs to pick one physical
+ * eraseblock of two (P or P1), the @copy_flag of the newer one (P1) is
+ * examined. If it is cleared, the situation* is simple and the newer one is
+ * picked. If it is set, the data CRC of the copy (P1) is examined. If the CRC
+ * checksum is correct, this physical eraseblock is selected (P1). Otherwise
+ * the older one (P) is selected.
+ *
+ * Note, there is an obsolete @leb_ver field which was used instead of @sqnum
+ * in the past. But it is not used anymore and we keep it in order to be able
+ * to deal with old UBI images. It will be removed at some point.
+ *
+ * There are 2 sorts of volumes in UBI: user volumes and internal volumes.
+ * Internal volumes are not seen from outside and are used for various internal
+ * UBI purposes. In this implementation there is only one internal volume - the
+ * layout volume. Internal volumes are the main mechanism of UBI extensions.
+ * For example, in future one may introduce a journal internal volume. Internal
+ * volumes have their own reserved range of IDs.
+ *
+ * The @compat field is only used for internal volumes and contains the "degree
+ * of their compatibility". It is always zero for user volumes. This field
+ * provides a mechanism to introduce UBI extensions and to be still compatible
+ * with older UBI binaries. For example, if someone introduced a journal in
+ * future, he would probably use %UBI_COMPAT_DELETE compatibility for the
+ * journal volume.  And in this case, older UBI binaries, which know nothing
+ * about the journal volume, would just delete this volume and work perfectly
+ * fine. This is similar to what Ext2fs does when it is fed by an Ext3fs image
+ * - it just ignores the Ext3fs journal.
+ *
+ * The @data_crc field contains the CRC checksum of the contents of the logical
+ * eraseblock if this is a static volume. In case of dynamic volumes, it does
+ * not contain the CRC checksum as a rule. The only exception is when the
+ * data of the physical eraseblock was moved by the wear-leveling unit, then
+ * the wear-leveling unit calculates the data CRC and stores it in the
+ * @data_crc field. And of course, the @copy_flag is %in this case.
+ *
+ * The @data_size field is used only for static volumes because UBI has to know
+ * how many bytes of data are stored in this eraseblock. For dynamic volumes,
+ * this field usually contains zero. The only exception is when the data of the
+ * physical eraseblock was moved to another physical eraseblock for
+ * wear-leveling reasons. In this case, UBI calculates CRC checksum of the
+ * contents and uses both @data_crc and @data_size fields. In this case, the

+ * @reserved_pebs: how many physical eraseblocks are reserved for this volume
+ * @alignment: volume alignment
+ * @data_pad: how many bytes are unused at the end of the each physical
+ * eraseblock to satisfy the requested alignment
+ * @vol_type: volume type (%UBI_DYNAMIC_VOLUME or %UBI_STATIC_VOLUME)
+ * @upd_marker: if volume update was started but not finished
+ * @name_len: volume name length
+ * @name: the volume name
+ * @flags: volume flags (%UBI_VTBL_AUTORESIZE_FLG)
+ * @padding: reserved, zeroes
+ * @crc: a CRC32 checksum of the record
+ *
+ * The volume table records are stored in the volume table, which is stored in
+ * the layout volume. The layout volume consists of 2 logical eraseblock, each
+ * of which contains a copy of the volume table (i.e., the volume table is
+ * duplicated). The volume table is an array of &struct ubi_vtbl_record
+ * objects indexed by the volume ID.
+ *
+ * If the size of the logical eraseblock is large enough to fit
+ * %UBI_MAX_VOLUMES records, the volume table contains %UBI_MAX_VOLUMES
+ * records. Otherwise, it contains as many records as it can fit (i.e., size of
+ * logical eraseblock divided by sizeof(struct ubi_vtbl_record)).
+ *
+ * The @upd_marker flag is used to implement volume update. It is set to %1
+ * before update and set to %0 after the update. So if the update operation was
+ * interrupted, UBI knows that the volume is corrupted.
+ *
+ * The @alignment field is specified when the volume is created and cannot be
+ * later changed. It may be useful, for example, when a block-oriented file
+ * system works on top of UBI. The @data_pad field is calculated using the
+ * logical eraseblock size and @alignment. The alignment must be multiple to the
+ * minimal flash I/O unit. If @alignment is 1, all the available space of
+ * the physical eraseblocks is used.
+ *
+ * Empty records contain all zeroes and the CRC checksum of those zeroes.

+ * Falcon hardware access
+ *
+ **************************************************************************
+ *
+ * Notes on locking strategy:
+ *
+ * Most Falcon registers require 16-byte (or 8-byte, for SRAM
+ * registers) atomic writes which necessitates locking.
+ * Under normal operation few writes to the Falcon BAR are made and these
+ * registers (EVQ_RPTR_REG, RX_DESC_UPD_REG and TX_DESC_UPD_REG) are special
+ * cased to allow 4-byte (hence lockless) accesses.
+ *
+ * It *is* safe to write to these 4-byte registers in the middle of an
+ * access to an 8-byte or 16-byte register.  We therefore use a
+ * spinlock to protect accesses to the larger registers, but no locks
+ * for the 4-byte registers.
+ *
+ * A write barrier is needed to ensure that DW3 is written after DW0/1/2
+ * due to the way the 16byte registers are "collected" in the Falcon BIU
+ *
+ * We also lock when carrying out reads, to ensure consistency of the
+ * data (made possible since the BIU reads all 128 bits into a cache).
+ * Reads are very rare, so this isn't a significant performance
+ * impact.  (Most data transferred from NIC to host is DMAed directly
+ * into host memory).
+ *
+ * I/O BAR access uses locks for both reads and writes (but is only provided
+ * for testing purposes).

+ * rx_alloc_method - RX buffer allocation method
+ *
+ * This driver supports two methods for allocating and using RX buffers:
+ * each RX buffer may be backed by an skb or by an order-n page.
+ *
+ * When LRO is in use then the second method has a lower overhead,
+ * since we don't have to allocate then free skbs on reassembled frames.
+ *
+ * Values:
+ *   - RX_ALLOC_METHOD_AUTO = 0
+ *   - RX_ALLOC_METHOD_SKB  = 1
+ *   - RX_ALLOC_METHOD_PAGE = 2
+ *
+ * The heuristic for %RX_ALLOC_METHOD_AUTO is a simple hysteresis count
+ * controlled by the parameters below.
+ *
+ *   - Since pushing and popping descriptors are separated by the rx_queue
+ *     size, so the watermarks should be ~rxd_size.
+ *   - The performance win by using page-based allocation for LRO is less
+ *     than the performance hit of using page-based allocation of non-LRO,
+ *     so the watermarks should reflect this.
+ *
+ * Per channel we maintain a single variable, updated by each channel:
+ *
+ *   rx_alloc_level += (lro_performed ? RX_ALLOC_FACTOR_LRO :
+ *                      RX_ALLOC_FACTOR_SKB)
+ * Per NAPI poll interval, we constrain rx_alloc_level to 0..MAX (which
+ * limits the hysteresis), and update the allocation strategy:
+ *
+ *   rx_alloc_method = (rx_alloc_level > RX_ALLOC_LEVEL_LRO ?

+/* Thanks to Axel Alatalo <axel@rubico.se> for fixing sport rx bug. Sometimes
+ * sport receives data incorrectly. The following is Axel's words.
+ * As EE-191, sport rx samples 3 times of the UART baudrate and takes the
+ * middle smaple of every 3 samples as the data bit. For a 8-N-1 UART setting,
+ * 30 samples will be required for a byte. If transmitter sends a 1/3 bit short
+ * byte due to buadrate drift, then the 30th sample of a byte, this sample is
+ * also the third sample of the stop bit, will happens on the immediately
+ * following start bit which will be thrown away and missed. Thus since parts
+ * of the startbit will be missed and the receiver will begin to drift, the
+ * effect accumulates over time until synchronization is lost.
+ * If only require 2 samples of the stopbit (by sampling in total 29 samples),
+ * then a to short byte as in the case above will be tolerated. Then the 1/3
+ * early startbit will trigger a framesync since the last read is complete
+ * after only 2/3 stopbit and framesync is active during the last 1/3 looking
+ * for a possible early startbit. */

+ * This driver handles the USB Device Controller (UDC) in Intel's PXA 27x
+ * series processors.
+ *
+ * Such controller drivers work with a gadget driver.  The gadget driver
+ * returns descriptors, implements configuration and data protocols used
+ * by the host to interact with this device, and allocates endpoints to
+ * the different protocol interfaces.  The controller driver virtualizes
+ * usb hardware so that the gadget drivers will be more portable.
+ *
+ * This UDC hardware wants to implement a bit too much USB protocol. The
+ * biggest issues are:  that the endpoints have to be set up before the
+ * controller can be enabled (minor, and not uncommon); and each endpoint
+ * can only have one configuration, interface and alternative interface
+ * number (major, and very unusual). Once set up, these cannot be changed
+ * without a controller reset.
+ *
+ * The workaround is to setup all combinations necessary for the gadgets which
+ * will work with this driver. This is done in pxa_udc structure, statically.
+ * See pxa_udc, udc_usb_ep versus pxa_ep, and matching function find_pxa_ep.
+ * (You could modify this if needed.  Some drivers have a "fifo_mode" module
+ * parameter to facilitate such changes.)
+ *
+ * The combinations have been tested with these gadgets :
+ *  - zero gadget
+ *  - file storage gadget
+ *  - ether gadget
+ *
+ * The driver doesn't use DMA, only IO access and IRQ callbacks. No use is
+ * made of UDC's double buffering either. USB "On-The-Go" is not implemented.
+ *
+ * All the requests are handled the same way :
+ *  - the drivers tries to handle the request directly to the IO
+ *  - if the IO fifo is not big enough, the remaining is send/received in
+ *    interrupt handling.

+ * Context : when in_interrupt() or with ep->lock held
+ *
+ * Tries to transfer all pending request data into the endpoint and/or
+ * transfer all pending data in the endpoint into usb requests.
+ * Handles states of ep0 automata.
+ *
+ * PXA27x hardware handles several standard usb control requests without
+ * driver notification.  The requests fully handled by hardware are :
+ *  SET_ADDRESS, SET_FEATURE, CLEAR_FEATURE, GET_CONFIGURATION, GET_INTERFACE,
+ *  GET_STATUS
+ * The requests handled by hardware, but with irq notification are :
+ *  SYNCH_FRAME, SET_CONFIGURATION, SET_INTERFACE
+ * The remaining standard requests really handled by handle_ep0 are :
+ *  GET_DESCRIPTOR, SET_DESCRIPTOR, specific requests.
+ * Requests standardized outside of USB 2.0 chapter 9 are handled more
+ * uniformly, by gadget drivers.
+ *
+ * The control endpoint state machine is _not_ USB spec compliant, it's even
+ * hardly compliant with Intel PXA270 developers guide.
+ * The key points which inferred this state machine are :
+ *   - on every setup token, bit UDCCSR0_SA is raised and held until cleared by
+ *     software.
+ *   - on every OUT packet received, UDCCSR0_OPC is raised and held until
+ *     cleared by software.
+ *   - clearing UDCCSR0_OPC always flushes ep0. If in setup stage, never do it
+ *     before reading ep0.
+ *   - irq can be called on a "packet complete" event (opc_irq=1), while
+ *     UDCCSR0_OPC is not yet raised (delta can be as big as 100ms
+ *     from experimentation).
+ *   - as UDCCSR0_SA can be activated while in irq handling, and clearing
+ *     UDCCSR0_OPC would flush the setup data, we almost never clear UDCCSR0_OPC
+ *     => we never actually read the "status stage" packet of an IN data stage
+ *     => this is not documented in Intel documentation
+ *   - hardware as no idea of STATUS STAGE, it only handle SETUP STAGE and DATA
+ *     STAGE. The driver add STATUS STAGE to send last zero length packet in
+ *     OUT_STATUS_STAGE.
+ *   - special attention was needed for IN_STATUS_STAGE. If a packet complete
+ *     event is detected, we terminate the status stage without ackowledging the
+ *     packet (not to risk to loose a potential SETUP packet)

+ * Endpoint definitions
+ *
+ * Once enabled, pxa endpoint configuration is freezed, and cannot change
+ * unless a reset happens or the udc is disabled.
+ * Therefore, we must define all pxa potential endpoint definitions needed for
+ * all gadget and set them up before the udc is enabled.
+ *
+ * As the architecture chosen is fully static, meaning the pxa endpoint
+ * configurations are set up once and for all, we must provide a way to match
+ * one usb endpoint (usb_ep) to several pxa endpoints. The reason is that gadget
+ * layer autoconf doesn't choose the usb_ep endpoint on (config, interface, alt)
+ * criteria, while the pxa architecture requires that.
+ *
+ * The solution is to define several pxa endpoints matching one usb_ep. Ex:
+ *   - "ep1-in" matches pxa endpoint EPA (which is an IN ep at addr 1, when
+ *     the udc talks on (config=3, interface=0, alt=0)
+ *   - "ep1-in" matches pxa endpoint EPB (which is an IN ep at addr 1, when
+ *     the udc talks on (config=3, interface=0, alt=1)
+ *   - "ep1-in" matches pxa endpoint EPC (which is an IN ep at addr 1, when
+ *     the udc talks on (config=2, interface=0, alt=0)
+ *
+ * We'll define the pxa endpoint by its index (EPA => idx=1, EPB => idx=2, ...)

  * Special thanks to Intel and VIA for providing host controllers to

- *
- * HISTORY:
- *
- * 2004-05-10 Root hub and PCI suspend/resume support; remote wakeup. (db)
- * 2004-02-24 Replace pci_* with generic dma_* API calls (dsaxena@plexity.net)
- * 2003-12-29 Rewritten high speed iso transfer support (by Michal Sojka,
- *	<sojkam@centrum.cz>, updates by DB).
- *
- * 2002-11-29	Correct handling for hw async_next register.
- * 2002-08-06	Handling for bulk and interrupt transfers is mostly shared;
- *	only scheduling is different, no arbitrary limitations.
- * 2002-07-25	Sanity check PCI reads, mostly for better cardbus support,
- *	clean up HC run state handshaking.
- * 2002-05-24	Preliminary FS/LS interrupts, using scheduling shortcuts
- * 2002-05-11	Clear TT errors for FS/LS ctrl/bulk.  Fill in some other
- *	missing pieces:  enabling 64bit dma, handoff from BIOS/SMM.
- * 2002-05-07	Some error path cleanups to report better errors; wmb();
- *	use non-CVS version id; better iso bandwidth claim.
- * 2002-04-19	Control/bulk/interrupt submit no longer uses giveback() on
- *	errors in submit path.  Bugfixes to interrupt scheduling/processing.
- * 2002-03-05	Initial high-speed ISO support; reduce ITD memory; shift
- *	more checking to generic hcd framework (db).  Make it work with
- *	Philips EHCI; reduce PCI traffic; shorten IRQ path (Rory Bolt).
- * 2002-01-14	Minor cleanup; version synch.
- * 2002-01-08	Fix roothub handoff of FS/LS to companion controllers.
- * 2002-01-04	Control/Bulk queuing behaves.
- *
- * 2001-12-12	Initial patch version for Linux 2.5.1 kernel.
- * 2001-June	Works with usb-storage and NEC EHCI on 2.4

  *
- * This driver is written to be used with the Hecuba display controller
- * board, and tested with the EInk 800x600 display in 1 bit mode.
- * The interface between Hecuba and the host is TTL based GPIO. The
- * GPIO requirements are 8 writable data lines and 6 lines for control.
- * Only 4 of the controls are actually used here but 6 for future use.
- * The driver requires the IO addresses for data and control GPIO at
- * load time. It is also possible to use this display with a standard
- * PC parallel port.
+ * This driver is written to be used with the Hecuba display architecture.
+ * The actual display chip is called Apollo and the interface electronics
+ * it needs is called Hecuba.
  *
- * General notes:
- * - User must set hecubafb_enable=1 to enable it
- * - User must set dio_addr=0xIOADDR cio_addr=0xIOADDR c2io_addr=0xIOADDR
+ * It is intended to be architecture independent. A board specific driver
+ * must be used to perform all the physical IO interactions. An example
+ * is provided as n411.c

+ * Xen event channels
+ *
+ * Xen models interrupts with abstract event channels.  Because each
+ * domain gets 1024 event channels, but NR_IRQ is not that large, we
+ * must dynamically map irqs<->event channels.  The event channels
+ * interface with the rest of the kernel by defining a xen interrupt
+ * chip.  When an event is recieved, it is mapped to an irq and sent
+ * through the normal interrupt processing path.
+ *
+ * There are four kinds of events which can be mapped to an event
+ * channel:
+ *
+ * 1. Inter-domain notifications.  This includes all the virtual
+ *    device events, since they're driven by front-ends in another domain
+ *    (typically dom0).
+ * 2. VIRQs, typically used for timers.  These are per-cpu events.
+ * 3. IPIs.
+ * 4. Hardware interrupts. Not supported at present.
+ *
