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:
  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 0.47. Tagged as 'NetBSD-0_47'

	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.
Detail:
Admin:
	Castle, Dan Ellis, NetBSD added IP. Tested at Castle. Will be
	beta tested at this revision level before full release.


Version 0.39. Tagged as 'NetBSD-0_39'

        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.

         Castle + D Ellis added IP


Version 0.35. Tagged as 'NetBSD-0_35'

        USB2 further debugged.
Detail:
        Check in prior to second beta release. Improvements also to
        softloading of replacement modules.
Admin:
        Checked with JB .. further crosschecking is still needed for rhenium.
        Castle/D Ellis added ip from NetBSD sources


Version 0.33. Tagged as 'NetBSD-0_33'

Update of EHCIDriver to current NetBSD, together with needed changes in both OHCIDriver and USBDriver.

Detail:
        Code may change before formal release .. will be beta released
        ... Entered to CVS to get new version numbers, and for
        the record.
Admin:
        Castle/netbsd added IP .. will be tested more fully before
        formal release. Still to be verified on Rhenium.


Version 0.31. Tagged as 'NetBSD-0_31'

change to OHCIModule to pay heed to number of OHCI i/f reported by HAL (in Rhenium).. various other small adjustments to improve softloadability, both in OHCI and EHCI drivers.

Detail:
Admin:
    tested on iyonix and on rhenium
    castle added IP


Version 0.30. Tagged as 'NetBSD-0_30'

  'blocked' several holes that could cause freezes with awkward
  usb devices.  Added latest changes from Dan Ellis too , especially for USB2
Detail:
 many
Admin:
 Tested in ROM at Castle, and beta tested with users


Version 0.28. Tagged as 'NetBSD-0_28'

Version 0.27. Tagged as 'NetBSD-0_27'

Version 0.26. Tagged as 'NetBSD-0_26'

Detail:
  * All modules will now rmkill/rmload more reliably
  * Keyboard driver disables kernel debounce on new enough kernels, needed
    for many PS2-USB adaptors, bar code scanners etc
  * Mouse driver will scroll wheel scroll any windows that do respond to
    scroll events, otherwise it issues PointerReason_WheelChange (9) to an
    external WimpScroll module
  * Several bugs and an interrupt hole resolved
Admin:
  Tested at Framlingham.

Version 0.25. Tagged as 'NetBSD-0_25'

Version 0.23. Tagged as 'NetBSD-0_23'

Version 0.22. Tagged as 'NetBSD-0_22'

Detail:
  NetBSD/FreeBSD differences in the naming of certain macros are now resolved
  in TCPIPLibs instead of locally. Also some reordering in the !Mk files in
  order to work with current versions of Zap.
Admin:
  Builds against TCPIPLibs 5.47. Note that this version of the USB sources
  also now requires TCPIPLibs 5.47.

Version 0.21. Tagged as 'NetBSD-0_21'

> Reduce root port reset delay to 50ms from 250ms to work with Chicony
> keyboards (again).  Comment out duplicate free(udev) at end of
> usbmodule:config_detach.

Version 0.20. Tagged as 'NetBSD-0_20'

Version 0.19. Tagged as 'NetBSD-0_19'

Added new CallDevice reason code (&80000005) to clear a stall condition on a pipe with a given FileSwitch handle

New usbdevs and usbdevs_data from NetBSD
Rewrote power source detection to skirt round dodgy devices which say
they're self powered,set MaxPower=0,and don't respond to a getstatus()
Copes better with devices being unplugged while a transfer using them is active

Version 0.17. Tagged as 'NetBSD-0_17'

Detail:
  * Errors now use the allocated error number base, &819000, instead of a
    base in the private range, &50000000. "USB transfer failed" errors now
    have use a sub-range of error numbers from &819020; the original BSD
    error number can be retrieved from the bottom 5 bits of the RISC OS
    error number.
  * Service_USB 1 now returns the list in the order in which the devices,
    rather than in the reverse order as previous versions of the module did.
  * A little tweaking of h/usb_port to reduce compiler warnings.
  * Some compiler-satisfying changes to allow use of packed structures.
    (However, the compiler doesn't seem to work correctly yet, so this is
    currently switched out using -DDISABLE_PACKED on the command line.)
  * Added full stops to end of star command help strings for consistency
    with rest of OS.
  * New exports: USBDevFS (moved here from ^.h) and a few files in dev/usb/h
    and sys/h.
Admin:
  Error number overhaul and new exports are both required by SCSISoftUSB.

Version 0.16. Tagged as 'NetBSD-0_16'

Put the port reset delay back to 50ms.Not sure why NetBSD decided to change that but it broke the Chicony keyboard supplied in Castle's Iyonix.

Version 0.15. Tagged as 'NetBSD-0_15'

Added stuff to delete the DeviceFS$USB*$Options variables when the module is
RMkilled.

Version 0.12. Tagged as 'NetBSD-0_12'

Correction of spelling of busses to buses (noun plural).
OHCIdriver only responds to PCI service call to lookup vendor name when
the device is of class OHCI controller.

Version 0.01. Tagged as 'NetBSD-0_01'

This is the initial import of prototype USB drivers written for the OHCI chip on the customer L board.

Details:
  The drivers are for mouse, keyboard and combined keyboard and mouse.  They
assume that the correct device is going to be plugged in, not reading the
descriptors at all.  Once the mouse is plugged in, it will become the active
pointer device, reverting to the previous one when extracted.

Admin:
  The prototypes have been tested on a SDB customer L board, but require a couple
of pokes to the reset and configuration register to get them going:
  memorya f99f611c 3840 works on the SDB but will be different on the customer L board
