Detail:
  dev/usb/h/usb_port - Implement usb_syncmem to call the appropriate memory barrier function. Required for when PCI_RAMAlloc starts returning Normal, non-cacheable memory rather than Device (although technically these barriers have always been needed for ARMv6+)
  build/c/port - Memory barrier implementation; uses the appropriate OS routine if available, otherwise uses a null op.
  build/Version - Bump EHCIDriver version number (the only module that uses these barriers so far)

Version 0.97. Tagged as 'NetBSD-0_97'

Exposed possible return with reserved bit 8 set when enter was pressed.

Version 0.91. Tagged as 'NetBSD-0_91'

From NetBSD revision 1.687, this adds the 9514 hub featured on the Pandaboard.
Tested on a Pandaboard rev A3, now named in *USBDEVICES.

Version 0.90. Tagged as 'NetBSD-0_90'

OHCIDriver (only) had sketchy support for a HAL based scheme for controlling the port power and monitor overcurrent. However the implementation was limited to supporting the single port required for an embedded product (aka Rhenium in the CVS history). The change makes it follow a model much more akin to the HAL_TimerDevice/HAL_TimerIRQStatus/HAL_TimerIRQClear set of functions.
Version:
  Bumped OHCIDriver and USBDriver version numbers.
ohcimodule.c:
  Use some defines from OsBytes.h.
  Group the debug variables within the OHCI_DEBUG define so they go away in the release case.
  Allow for up to 15 ports to be controlled via the revised HAL API, and pass something other than a hardwired controller of 0 when controlling/monitoring power.
  Enumerate the device numbers for overcurrent monitoring on startup.
  Deal with the possibility of one (or more) of the device numbers being shared interrupts.
  Squash a few trivial compiler warnings.
ohcimodhead.cmhg:
  rename the handler/entry to reflect their use for overcurrent
ohci.c:
  Allow for up to 15 ports to be controlled by passing in the port index where needed.
usb_subr.c/usbdivar.h:
  Remove a RISC OS-ism in datatoggle, to converge with NetBSD a bit.
ehcivar.h/usb_port.h:
  Relocate the overrides for mutex_ functions here since this is the only controller using them. Previously when in "usb_port.h" they would indirectly get dragged in ia the nested include in "usb.h". The could in fact now be implemented using SyncLib, an exercise left to the reader.
usb.h
  Merge some of the device classes and other allocations from NetBSD.

While it's not been possible to test the revised API, due to not having sight of the original platform on which it was implemented, none of the actively maintained HALs currently use the HAL based power and overcurrent scheme anyway, so the new code never gets called. In that respect, it's no more broken then the previous single port-single controller version.

Version 0.89. Tagged as 'NetBSD-0_89'

Detail:
  build/Version - Bump EHCIDriver version number
  build/c/ehcihal, build/c/ehcimodule, build/c/ohcimodule - Use the HAL USB controller type & flag definitions from Hdr:HALEntries instead of using magic numbers
  build/c/ehcimodule - Avoid double-read of hardware register in debug version of bus_space_read_4(); ensures that we report the value that's actually returned to the driver
  dev/usb/c/ehci - Merge in the following revisions from NetBSD:
  - 1.172, 1.173, 1.178, 1.193 - Support for controllers with embedded transaction translators
  - 1.174 - alloc_sqtd_chain() fix for short packets that end on page boundaries
  - 1.179 - ehci_set_qh_qtd() fixed to terminate alternate next qTD pointer with EHCI_NULL, not 0

Version 0.88. Tagged as 'NetBSD-0_88'

Detail:
  dev/usb/usbdevs - Updated to the latest version from the NetBSD CVS, mainly for several new DisplayLink product IDs. Merged in our TouchBook definitions from rev 1.5, and commented out a couple of duplicate products.
  dev/usb/c/usb_quirks - Updated to cope with MetaGeek vendor being renamed to Misc
  build/Version - Bump USBDriver version number
Admin:
  Tested in OMAP3 ROM build


Version 0.86. Tagged as 'NetBSD-0_86'

Detail:
  build/c/usbhal - Restructured triggercbs() so that it doesn't use irqsema to prevent callbacks triggering recursively, as this behaviour can be required sometimes (e.g. xfer timeout callback for a blocking xfer that's being performed within the bus explore callback).
  Instead, a 'callbacks needed' flag is used to decide whether callbacks should be processed, which operates in a similar way to the kernel's CBack_VectorReq flag - once a triggercbs() instance starts processing callbacks, no other calls will process them until a new callback is inserted.
  Also fixed indexing of the callback array within triggercbs() to correctly deal with wrap-around
  build/Hdr/usbhal, dev/usb/h/usbhal - Add cbs_needed to workspace
Admin:
  Tested on BB-xM with high processor vectors
  Fixes hang during boot time keyboard scan that was seen when certain devices were connected


Version 0.84. Tagged as 'NetBSD-0_84'

Detail:
  dev/usb/c/usb_subr - Merge in latest usbd_new_device() changes from NetBSD (rev 1.196). This primarily changes around the order of the SET_ADDRESS and descriptor get calls, as well as changing the descriptor get to request 64 bytes of data instead of 8.
  build/Version - Bump USBDriver version number
Admin:
  Tested on BB-xM, Raspberry Pi, Iyonix ROM softload
  Fixes issue reported on forums with Raspberry Pi Model A not initialising correctly when connected as a device. Previously it was getting stuck fetching the descriptors after setting the address.
  http://www.riscosopen.org/forum/forums/5/topics/2534


Version 0.82. Tagged as 'NetBSD-0_82'

Merge of code change from revision 1.152 of usbdi.c from NetBSD, function usb_transfer_complete - this just swaps the ordering around to ensure the callback & done are in the right order.
Built, but not tested.

Version 0.81. Tagged as 'NetBSD-0_81'

Detail:
  build/Makefile, build/!MkDebug,fd7 - Debug versions of the modules can now be built just by passing "DEBUG=TRUE" to amu
  build/!MkRhenium,fd7 - Deleted obsolete file
  build/Version - Increased version numbers
  build/c/ehcihal, build/c/ehcimodule, build/c/ohcimodule - Only accept USB controllers if HAL_USBControllerInfo says the struct size is an exact match with what we expect. Rework USB controller enumeration to allow modules to properly support both PCI and HAL controllers being available on the same machine, and without RHENIUM switch (module sources only).
  build/c/ehcimodule - Get rid of remaining RHENIUM bits; RHENIUM flag no longer needed for 32bit wide register reads/writes to be supported
  build/c/ohcimodule, build/cmhg/ohcimodhead, dev/usb/c/ohci - Get rid of remaining RHENIUM bits; RHENIUM flag no longer needed for HAL port power controls to be supported.
  build/c/usbhal, build/c/usbmodule, dev/usb/c/uhub, dev/usb/h/usb_port - Get rid of empty riscos_failed_device function
  build/s/call_veneer, build/s/triggercbs - Use Entry/EXIT macros to avoid single-reg LDM/STM performance warnings. Convert tabs to spaces.
  dev/usb/h/usb - Get rid of RHENIUM switch on USB_PORT_RESET_DELAY. Now always uses non-RHENIUM value of 100ms.
Admin:
  Tested on rev A2 BB-xM, Iyonix, Raspberry Pi


Version 0.71. Tagged as 'NetBSD-0_71'

In particular, the SMSC ethernet controller and hub on the Beagleboard
xm.
Changed pointer assignments & comparisons with 0 to be NULL for clarity.
Implement a left trim function for any printed out strings obtained from
the device (to mirror usbd_trim_spaces) so that when dopey manufacturers
use a space instead of their company name everything lines up still.

Version 0.68. Tagged as 'NetBSD-0_68'

Detail:
  dev/usb/c/ehci - Force all EHCI data buffers to be 512 byte aligned.
  This is a workaround for what I believe is a bug in the DM37x EHCI controller - It looks like if the last packet of a bulk in transfer is a short packet, and that packet crosses a page boundary, then the second half of the packet doesn't seem to be written out to the correct address in memory.
  Version - increased EHCI module version number
Admin:
  Tested on rev A2 BB-xM
  Fixes issue reported on forums with unreliable USB ethernet:
  http://www.riscosopen.org/forum/fourms/5/topics/828#posts-9691


Version 0.65. Tagged as 'NetBSD-0_65'

Detail:
  dev/usb/c/ehci, dev/usb/c/ohci - Fixed device descriptor and config descriptor reads writing outside the destination buffer if the buffer was small enough.
  build/Version - Incremented EHCI & OHCI version numbers & dates
Admin:
  Tested in OMAP3 ROM & Iyonix ROM softload


Version 0.63. Tagged as 'NetBSD-0_63'

Update HAL USB code for new HAL_KbdScanInterrupt behaviour. Fix data aborts during keyboard scanning.

Detail:
  build/c/usbhal, build/h/usbhal - Updated USBHAL_KbdScanInterrupt to behave the same way HAL_KbdScanInterrupt is now expected to behave.
  build/c/ehci, build/c/ohci - Fixed some root hub emulation code which was writing to a global structure before copying it into the destination buffer. Although this works fine in ROM modules it was causing data aborts in the USB HAL libraries due to lack of automatic RW data relocation by the compiler.
  build/Version - Updated version numbers
Admin:
  Tested on rev C2 BB.


Version 0.62. Tagged as 'NetBSD-0_62'

Detail:
  build/Makefile, build/OBJEHCIDriver, build/OBJOHCIDriver, build/OBJUSBDriver - Modified makefiles to build the HAL libs during the export libs phase
  build/!MkHAL,fd7 - Handy script for building the HAL libs
  build/Hdr/usbhal - Header containing definitions for the assembler code. Also gets exported so that HALs know how much workspace to reserve.
  build/c/usbhal - HAL version of usbmodule.c & port.c. Also contains the keyboard scan code, adapted from the code in the Tungsten HAL.
  build/s/porthal - Assembler versions of some port.c routines that were easier to do in assembler than C
  build/s/halheap - OS_Heap code that's been adapted for use in the HAL. Could easily be changed into a standalone library instead of being part of the HAL USB libs. Supports memory-efficient allocation of aligned blocks.
  build/c/ehcihal - HAL version of ehcimodule.c. Currently only supports EHCI controllers exposed via HAL_USBControllerInfo (i.e. no PCI support)
  build/c/ehcimodule, build/c/ohcimodule, build/c/port - Moved riscos_irq_clear into port.c. Removed unused microtime() function.
  build/c/usbmouse - Strip out some debug-related code in non-debug builds
  build/Version - Updated version numbers
  dev/usb/c/ehci, dev/usb/h/ehcivar - Adapted to add support for the HAL build. Apart from the base changes, the code has also been tweaked to significantly reduce the amount of memory used at runtime by the HAL version of the driver.
  dev/usb/c/hid, dev/usb/c/uhub, dev/usb/c/usb, dev/usb/c/usb_quirks, dev/usb/c/usb_subr, dev/usb/c/usbdi, dev/usb/c/usbdi_util, dev/usb/c/usbroothub_subr - Changes to support HAL builds. Mainly disabling bits that won't work in the HAL or disabling bits for RISC OS in general if they weren't being used in the first place.
  dev/usb/c/ohci, dev/usb/h/ohcivar - Basic changes to support HAL builds. However HAL OHCI support is still incomplete.
  dev/usb/h/usb_port - Added support for the HAL build. Also tweaked logprintf definition to get rid of logprintf calls entirely in non-debug builds.
  dev/usb/h/usbdivar - Added support for the HAL build.
  dev/usb/h/usbhal - New header used by the HAL build. Gets included by every C file to ensure the compiler doesn't use sb, and contains structs/macros to allow access to the shared workspace.
Admin:
  HAL & non-HAL builds tested on rev C2 BB, rev A2 BB-xM, rev C1 TouchBook.
  Non-HAL builds tested with Iyonix ROM softload.
  Needs latest Kernel source for OSEntries.h export.


Version 0.59. Tagged as 'NetBSD-0_59'

Detail:
  build/c/usbdi - Fix compiler warning in usbd_clear_endpoint_stall()
  build/c/usbmodule - Fix detach_device() to deregister any pending attach callback for the detaching device. Fixes crash seen when inserting 16GB USB stick into EHCI port of rev C2 beagleboard (a current surge or something causes the stick to immediately disconnect then reconnect, but the disconnect occurs before the initial attach callback)
  build/c/usbmodule - Fix device_initialise() to use a timeout of 0 if no timeout was specified in the DeviceFS special field
  build/c/usbmodule - Fix the new read_cb() buffer padding logic to only pad up to totalcount instead of filling the entire buffer
Admin:
  Tested on rev C2 beagleboard.
  This seems to fix the problems that were preventing Steffen Huber's USB CD code from working properly.


Version 0.56. Tagged as 'NetBSD-0_56'

Detail:
  dev/usb/c/hid, dev/usb/h/hid, dev/usb/c/ums - Updated to latest NetBSD versions (actually the version that was used for the recent core/EHCI update, so not 100% latest)
  build/c/usbmouse, dev/wscons/h/wsmousevar - Updated RISC OS USB mouse driver to be similar to the new NetBSD version. Also reformatted file to use tab char instead of inconsistent numbers of spaces for indentation.
  build/c/usbmouse, dev/usb/usbdevs - Added fix for broken TouchBook touchpad behaviour.
Admin:
  Tested with various mice on a beagleboard, and with the TouchBook touchpad.
  We should now have support for the W axis of mice, but that code is untested since I don't have any suitable mice to hand.


Version 0.53. Tagged as 'NetBSD-0_53'

Detail:
  EHCI driver update:
    dev/usb/c/ehci - Updated to latest NetBSD version, except for revisions 1.134 and 1.135 which are too invasive to merge in without updating the rest of the USB stack. This new version brings lots of bug fixes, and adds (untested on RISC OS) support for EHCI isochronous transfers.
    dev/usb/h/ehcivar - Updated to latest NetBSD version, except for the sc_bus splitting that was held back from the ehci.c update
    dev/usb/h/usb, dev/usb/h/usbdi, dev/usb/usbdivar - partial update to latest as required/possible
    dev/usb/c/usb_quirks, dev/usb/h/ehcireg, dev/usb/h/usb_mem, dev/usb/h/usb_quirks, dev/usb/h/usbhid, dev/usb/usbdevs, dev/usb/devlist2h.awk, dev/wscons/h/wsconsio, dev/wscons/h/wsmousevar - Updated to latest NetBSD versions
    dev/usb/c/usbroothub_subr, dev/usb/h/usbroothub_subr - New files brought in from NetBSD sources for use with new EHCI driver
    build/objehcidriver - Added usbroorhub_subr to EHCI driver
    dev/usb/h/usb_port - Added extra dummy functions as required by new EHCI driver
    dev/build/c/port - Added extra parameter to callout_init as required by new EHCI driver
  DeviceFS improvements:
    build/c/usbmodule - Added DeviceFSCallDevice_GetHandles2 as a replacement for Thomas Milius's backwards-incompatible GetHandles changes. Added DeviceFSCallDevice_GetSetOptions call to control RX padding and TX force-short-xfer features. These features can also be controlled at endpoint creation time by new fields in the filename. Also fixed packet padding to not fill the buffer with garbage or potentially crash when the padded area is more than one packet in length.
  New bus registration API:
    Changes made to the data structures that are shared between the modules means that new checks are needed to ensure USB modules with incompatible APIs are not used with one another.
    build/h/usbdivar - Since this seems to be the file containing the main structures that are shared, it now has a #define at the top indicating the first version of the USBDriver module that implemented the data structures within. This version number is used to check that the driver modules are compatible.
    build/cmhg/usbmodhead, build/h/usbdriver, build/c/usbmodule - Add a new SWI, USBDriver_Version, to return the version number of the USBDriver module. Used for both intra-stack API version checks and can be useful for external code that wants to query DeviceFS feature availability.
    build/c/usbmodule, build/c/ehcimodule, build/c/ohcimodule - Updated USBDriver_RegisterBus SWI and the code that calls it to pass the API version number (as defined in usbdivar.h) to USBDriver when attempting to reigster the bus. USBDriver then ensures the version matches that of itself, and if not refuses to allow the bus to register. EHCI & OHCI modules also check that USBDriver is new enough to implement this behaviour via the USBDriver_Version SWI.
  And finally:
    build/version - Incremented module version numbers.
    build/doc/usb - Updated with details of new features
Admin:
  Tested in ROM softload on Iyonix & beagleboard. Beagleboard hub issues seem to be resolved, and there are no new bugs that I can see.


Version 0.52. Tagged as 'NetBSD-0_52'

Add workaround for incorrect sizeof(usb_status_t), disable debug_set_stamp_debug(TRUE) to fix interrupt issue

Detail:
  build/c/ehcimodule, build/c/ohcimodule, build/c/usbmodule - Make sure that timestamped debug messages aren't used, as they appear to cause interrupts to be briefly enabled, which causes all kinds of problems in sensitive bits of the code.
  dev/usb/c/usbdi, dev/usb/c/usbdi_util, dev/usb/h/usb - Because DISABLE_PACKED is being used to compile the USB drivers, sizeof(usb_status_t) was being calculated as 4 bytes instead of 2. Somehow this works fine with the EHCI driver (and presumably the OHCI driver), but it was causing problems with the MUSBDriver, so a hardcoded size of 2 is now used.
Admin:
  Tested on rev C2 beagleboard.


Version 0.48. Tagged as 'NetBSD-0_48'

Add support for HAL enumerated USB EHCI controllers, use HAL_IRQClear when clearing EHCI/OHCI controller interrupts

Detail:
  * HAL enumeration of EHCI controllers is performed in the same manner as for OHCI, and protected by #ifdef RHENIUM. HAL_USBControllerInfo must return with the usbinfo type field set to 1 to indicate EHCI.
  * HAL_IRQClear is now called by the EHCI & OHCI modules after clearing the interrupt flag in the USB controller, to allow the HAL to reset the interrupt controller if required (e.g. for OMAP3)
  * EHCI module (for HAL EHCI controllers) now has the option of forcing all EHCI register access to be 32bit size & alignment (requirement is indicated in OMAP3 TRM, although USB did seem to function fine without)
  build/c/ehcimodule - Add enumeration of HAL USB controllers. Add support for forcing all EHCI register access to be 32bit size & alignment. Add riscos_irqclear() implementation. Guard against unexpected behaviour if PCI module isn't present.
  build/c/ohcimodule - Add riscos_irqclear() implementation. Guard against unexpected behaviour if PCI module isn't present.
  dev/usb/c/ehci, dev/usb/c/ohci - call riscos_irqclear() when appropriate
  dev/usb/h/usb_port - riscos_irqclear() prototype
Admin:
  Tested on rev C2 beagleboard. Untested on Iyonix, but should be fine.

Version 0.46. Tagged as 'NetBSD-0_46'

re-merged some items missed by Dan, and corrected usbmodule for 1 item missed earlier.. interrupt out endpoints noe demonstrated working

Detail:
Admin:  jb  Castle added IP


Version 0.45. Tagged as 'NetBSD-0_45'

Detail:
  There were many places where this was broken: the devicefs
interface was always starting off a read regardless of
whether it was an IN or OUT transfer, usbdi.c was setting
OUT interrupt transfers as repeating, which doesn't make sense,
and ohci.c was always making interrupt transfers OUT (this is
fixed in the latest BSD sources). Also the code which
unhalts endpoints at start of day has been removed, as this is
no longer in the BSD sources having been removed after it was
seend to have caused problems.

Admin:
  Tested with a CATC analyzer on an AverMedia FM radio. If now
operates properly with the code from Dave Higton.

Version 0.43. Tagged as 'NetBSD-0_43'

Detail:
	Includes several bug fixes and null pointer traps.
	Rhenium version reviewed and reset should be improved.
Admin:
	Tested in rhenium desktop build and iyonix build at castle

Version 0.40. Tagged as 'NetBSD-0_40'

	Inclusion of Mods to c.ehci (from Dan) to correctly handle low
	speed interrupt devices beyond USB2 hubs (i.e. keyboards and mice).
	Mod to EHCI resetting in service call handler to better cope with
	USBDriver being restarted 'underneath' it.

	beta tested at this revision level before full release.


Version 0.39. Tagged as 'NetBSD-0_39'

small change at start of pipe open process to accomodate error return provided by some mass storage devices.

Detail:
Admin:   tested at castle.. castle added ip


Version 0.38. Tagged as 'NetBSD-0_38'

        Added (and fixed code underlying) to give periodic
        explore of USB busses (cf NetBSD).
        Added USBDisover command to let user provoke this too.
        Reworked USB device number allocation to roll
        around at 999 to avoid field overflow in
        a number of places.
Detail:
Admin:  castle added IP. to be beta tested on beta test site


Version 0.37. Tagged as 'NetBSD-0_37'

Detail:
        USB_PORT_RESET_DELAY had been increased from 100 to 200ms in previous
        version. This was OK for most devices, and beneficial for some, BUT
        killed the Chicony keyboards shipped with many iyonix.. Delay has
        been reverted to 100ms, and is now run time alterable via the
        USB$PortResetDelay sysvar. This problem did not show up in beta testing!

Admin:  tested by JB with chicony.. delays up to around 160ms work with
        the chicony.
        Castle added IP

Version 0.36. Tagged as 'NetBSD-0_36'

Detail:
         - VarVal launching.. string length was incorrectly calculated.
         - USB VarVals now correctly cleared if device failed during
           enumeration, after first SetVarVal call.
         - Triggercbs() modified to check interrupt context and be
           refuse (quietly) to trigger callbacks if interrupts threaded
           (result of possible issue .. but perhaps wise)
         - Added third QueryDelay variable, and an Info file to describe
           what does what.
Admin:
         checked at Castle.. due for extended check via beta test site
         before formal release.
