Detail:
  Three main changes:
  * On odd-numbered (i.e. development) versions of the module, the UtilityModule will now take its date from the VersionNum file instead of using a hard-coded date.
  * All build versions now look for the new "extended ROM footer" (as created by romlinker 0.04+) at the end of the ROM image and use it to determine the ROM build date for return by OS_ReadSysInfo 9,2. Failing to find the build date in the footer will cause OS_ReadSysInfo 9,2 to return 0.
  * On odd-numbered versions, OS_Byte 0 will now use the ROM build date (as found in the extended footer) to generate the error block that's returned to the user. This seems OK as the PRM describes OS_Byte 0 as returning the "creation date of the operation system". Plus it's a convenient way of getting the ROM build date into the Switcher, since the switcher uses OS_Byte 0. If the extended footer can't be found (or if the string hasn't been initialised yet, e.g. before Service_PostInit) the code falls back to a hard-coded string containing the date from the VersionNum file.
  File changes:
  Makefile - Updated to not create the obsolete Time+Date file (previously used for the ROM build date)
  Version - Use date from VersionNum file for development builds
  hdr/Options - New UseNewFX0Error variable/option to make it easy to check which OS_Byte 0 variant should be enabled
  hdr/KernelWS - Added new string buffers & extended ROM footer pointer to workspace
  s/Middle - Updated OS_ReadSysInfo 9 code, and added utility functions for searching the extended ROM footer for certain tags
  s/NewReset - Added a couple of calls to initialise the new string buffers just prior to Service_PostInit. This is required since OS_Byte/OS_ReadSysInfo shouldn't enable interrupts, but date conversion relies on the Territory module, which may enable interrupts.
  s/PMF/osbyte - Updated OS_Byte 0 code
Admin:
  Tested in OMAP ROM, with and without the extended footer present.

Version 5.35, 4.79.2.98.2.20. Tagged as 'Kernel-5_35-4_79_2_98_2_20'

Fix error handling for sparse dynamic area resize operations, increase Cortex kernel version number to 5.15

Detail:
  s/ChangeDyn - Swap CMP with TEQ to avoid accidental clobbering of V flag before its state is checked on return from a SWI. Errors encountered during sparse dynamic area resize operations (OS_DynamicArea 9 & 10) should now be reported properly.
  Version - Update kernel version/date to 5.15, to match current HAL version. This change is to allow modules to properly detect whether the kernel has the sparse dynamic area fix - it does not (yet) mean that the Cortex kernel contains all the features of the current development HAL kernel!

Version 5.35, 4.79.2.72. Tagged as 'Kernel-5_35-4_79_2_72'

Now pads its HAL entry table with NullHALEntry if the HAL is providing fewer entries than the Kernel needs. Helps internal Kernel use of CallHAL, but doesn't affect external OS_Hardware users.

Version 5.35, 4.79.2.67. Tagged as 'Kernel-5_35-4_79_2_67'

  [Not fully implemented - for now leaves at least 16MB free if only
  one RAM area; was 1MB].
* Added HAL_USBControllerInfo, HAL_MonitorLeadID and HAL_Video_Render.
* Added HAL->OS call OS_IICOpV.
* OS_MMUControl now allows independent control of I and C bits.
* Added facility to deactivate keyboard debounce (magic word "NoKd" in
  R2 in KeyV 0).
* Fixed problem with RAM amounts not a multiple of 4MB.
* Supremacy bit (in VDU 19) now sets all 8 bits of supremacy.
* Added PaletteV 14 (reads gamma tables).
* Added Supremacy transfer functions (like gamma correction, but for
  supremacy). Allows easy global supremacy effects in a mode-independent
  fashion. Controlled with PaletteV 15,16.
* Added modes 50-53 (320x240, 1,2,4,8bpp). Intended for small LCD.
* Added 13.5kHz versions of TV modes (selected by Hdr:Machine).
* Upped desktop version to 5.06.

115200 baud not 9600 baud.
Fix to VDU despatch for ARMv4 and later.
Fixes to power on delete keyboard and keyboard timeout
Implemented MemoryReadPhys and MemoryAmounts with the HAL.

Version 5.35, 4.79.2.59. Tagged as 'Kernel-5_35-4_79_2_59'

OSDelink/RelinkApp now work on the list in opposite orders so that the order of vector claims doesn't get toggled.

Fix for *FX5 not working due to a TST having been swapped for CMP.
Checkprotectionlink option added to HAL version so CMOS lock is
implemented.
Updated HAL docs.

Version 5.35, 4.79.2.58. Tagged as 'Kernel-5_35-4_79_2_58'

Detail:
  * Merged in the change to RISC OS 4.02 kernel that moved the GSTrans
    workspace out of scratch space.
  * Fixed a few bugs in callback postponement, and interrupt holes in
    callback dispatch. See Docs.CallbackChange for full info.
  * Fixed SystemSizeCMOS to SysHeapCMOS - wouldn't build as was.
  * Added an export of a C version of Hdr:HALDevice, based on the Hdr2H
    translation but with an additional struct definition. Required by
    SoundControl 1.00.
  * Added some additional location and ID allocations to Hdr:HALDevice.
    Required by today's HAL and SoundControl.

Version 5.35, 4.79.2.56. Tagged as 'Kernel-5_35-4_79_2_56'

*Configure ANYTHINGsize was broken due to not setting R0 to ReadUnsigned
IIC ack message uninternationalised
OS_Memory was saying we only had 4M of RAM
VDU4 scrolling when output was switched to sprite was causing corruption
on use of CTRL-J and CTRL-K
Default SystemSize CMOS set to 32k

Version 5.35, 4.79.2.55. Tagged as 'Kernel-5_35-4_79_2_55'

Added 256-colour version of the (high-resolution only) teletext code, and support for teletext when hardware scroll is disabled. Both are required for Tungsten.

Turned off the module init/final service calls, since we still don't have an
allocation for them.
Upped the OS version number to 5.01.

Version 5.35, 4.79.2.53. Tagged as 'Kernel-5_35-4_79_2_53'

Detail:
  Lots of changes since last version, at least the following:
  * Updated OS timestamp, removed alpha status
  * Negative INKEY OS version changed to &AA
  * GraphicsV is now alocated vector number &2A
  * ROM moved up to &FC000000
  * Max application slot increased to 512 Mbytes (for now)
  * Max size of RMA increased to 256 Mbytes
  * RMA is now first-created dynamic area (so it gets lowest address after
    top of application slot)
  * OS_Memory 10 reimplemeted
  * New OS_ReadSysInfo 6 values 18-22 added
  * OS_ReadSysInfo 8 gains flag bit to indicate soft power-off
  * Misc internal top-bit-set-address fixes
  * *ChangeDynamicArea can take sizes in megabytes or gigabytes
  * Magic word "&off" in R0 passed to OS_Reset powers down if possible
  * Added acceleration: block copy; CLS; text window scroll up; rectangle
    fill
  * Disabled LED flashing in page mode (liable to crash)
  * Masked sprite plot and VDU 5 text avoids reading the screen if possible
  * Framestore made USR mode accessible
  * Fix for VDU 5,127 bug - now relies on font definitions being in extreme
    quarters of memory, rather than bottom half
  * Allocated 64-bit OS_Convert... SWIs
  * IIC errors use allocated error numbers
  * Looks for Dallas RTC before Philips RTC because we're using a Philips
    NVRAM device with the same ID
  * Fix to bug that meant the oscillator in the Dallas RTC wasn't enabled
  * Default mouse type (USB) changed to allocated number
  * Ram disc max size increased to 128 Mbytes (Ursula merge) and made
    cacheable for StrongARMs (not XScale)
  * Branch through zero handler now works in USR mode, by use of a
    trampoline in the system stack to allow PC-relative register storage
  * Address exception handler changed to not use 0 as workspace
  * OS_Memory 13 extended to allow specification of cacheability and access
    privileges
  * Added OS_Memory 16 to return important memory addresses
  * RISCOS_MapInIO() takes cacheable flag in bit 3, access permissions in
    bits 10 and 11, doubly-mapped flag in bit 20, and access permissions
    specified flag in bit 21
  * Bug fix in last version for application abort handlers didn't quite
    work; register shuffle required
  * "Module is not 32-bit compatible" error now reports the module name
  * Default configured language changed from 10 to 11 (now Desktop again)

Version 5.35, 4.79.2.48. Tagged as 'Kernel-5_35-4_79_2_48'

Check-in of the few last-minute changes for the Customer L demo. Nothing exciting, apart from an extended touchscreen API.

Version 5.35, 4.79.2.13. Tagged as 'Kernel-5_35-4_79_2_13'

Detail:
  When Machine=Phoebe the Kernel failed to build due to use of OSVersionID.
  Commented out this line.  Other machine settings unaffected.
Admin:
  Tested on Ursula build: Products/Ursula/modules (tag Ursula010a).

Version 5.19. Tagged as 'Kernel-5_19'

STB and NC builds. Remerged correctly.

Version 5.16. Tagged as 'Kernel-5_16'

  Ensured that M_Phoebe builds set UtilityModule version to 4.00
Detail:
  The softload utility relies on the existence of the extra reason codes
    to OS_ReadSysInfo introduced in Ursula.  The main kernel now supports
    these too (they are simply interfaces to read kernel capabilities and
    configuration - eg. addresses and sizes of UND and SVC mode stacks)
  Avoid OS_ReadSysInfo 9 - ROL have used it for reading the ROM personality
    information (and it's not in our kernel)
  Added some of the new macros into Copro15ops required by the ABT dump
    area code (returned by OS_ReadSysInfo 7) and added the code into ARM600
    to store abort information there.
Admin:
  Required by softload utility for Ursula builds.
  Tested on Risc PC.

Version 5.15. Tagged as 'Kernel-5_15'

Bandwidth limit for 7500FE fixed.
RO371Timings flag set to :LNOT:STB
