Detail:
  s/Middle - Added some new OS_ReadSysInfo 6 items which are needed by the zero page relocation kernel. Also duplicated some existing entries to avoid conflicts with ROL's allocations.
  hdr/OSRSI6, Makefile - New header listing OS_ReadSysInfo 6 items
  hdr/PublicWS - Duplicated the workspace definitions for &0-&4000, but with a 'Legacy_' prefix to their names. Also added some new entries as needed by the zero page relocation kernel. Once existing modules have been updated to use OS_ReadSysInfo & the Legacy_ definitions, the old defs will be removed.
  hdr/KernelWS - Removed 'Export_' prefix from all the exported workspace values, since the kernel can now use the original names directly
  hdr/Options - Dummy HiProcVecs option so merging things will be a bit cleaner

  Tested in ROM softload on Iyonix


Version 5.35, 4.79.2.118. Tagged as 'Kernel-5_35-4_79_2_118'

Detail:
  Makefile - A couple of makefile rules were invoking perl directly instead of using the more preferential ${PERL}. Fixed.
Admin:
  Tungsten ROM compiles OK, untested at runtime.


Version 5.35, 4.79.2.117. Tagged as 'Kernel-5_35-4_79_2_117'

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 operating 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 isn't 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 Tungsten ROM, with and without the extended footer present.


Version 5.35, 4.79.2.115. Tagged as 'Kernel-5_35-4_79_2_115'

Detail:
  Makefile - Added hdr.Variables to the C header export list
Admin:
  Fixes build errors with the latest Draw module


Version 5.35, 4.79.2.113. Tagged as 'Kernel-5_35-4_79_2_113'

Detail:
  Makefile - now exports a C version of hdr.OSEntries
Admin:
  Tested in Iyonix ROM softload.
  Needed for latest USB drivers to build.


Version 5.35, 4.79.2.112. Tagged as 'Kernel-5_35-4_79_2_112'

Detail:
  Some users reported problems building the sources if they had other
  installations of perl on their build machine. The build system was using a
  mixture of "perl" and "<Perl$Dir>.perl" to invoke the interpreter, and
  sometimes but not always using "do" to expand system variables on the
  command line. This has now been standardised to use "do <Perl$Dir>.perl in
  all cases, and where possible, to use the makefile macro ${PERL}.
Admin:
  Checked that a Tungsten build still works on a build machine with no other
  perl installation. "perl" was aliased to an error to ensure it wasn't used.

Version 5.35, 4.79.2.102. Tagged as 'Kernel-5_35-4_79_2_102'

Detail:
  Tightened up BBE resources export, to exclude in appropriate files (this
  component has a non-standard resources directory structure).
Admin:
  Tested in a Tungsten BBE build.

Retagged, since this won't affect any existing builds.

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.
Admin:
  Partially tested.

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

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

More stuff. Up to the desktop now; cache on, working keyboard. Some source restructuring to start to make splitting it up into several object files more feasible.

Version 5.35, 4.79.2.2. Tagged as 'Kernel-5_35-4_79_2_2'

* Added ARM_IMB and ARM_IMBRange SWIs as recommended by ARMv5.
* Some early prototype HAL bits popped in - a lot of source restructuring still
  to come.
* New debug target creates an AIF image with debug information, and translates
  this into an ASCII object file for the 16702B logic analyser.

Version 5.35, 4.79.2.1. Tagged as 'Kernel-5_35-4_79_2_1'

Detail:
  Hdr:RISCOS contains some of the most useful constant declarations,
    including the vector numbers and event numbers.  The new improved
    Hdr2H script is now capable of converting this header file into C
    too.  It exports it as <CExport$Dir>.Global.h.RISCOS.  It cannot
    interfere in existing code as it requires explicit inclusion as
    #include "Global/RISCOS.h".
  No actual kernel code changes.
Admin:
  File examined manually and checked for correctness against Hdr:RISCOS.
  Requires library 0.28 or later (RiscOS/Library  Tag: Library-0_28)

Version 4.82. Tagged as 'Kernel-4_82'

Modified HelpStrs (from which s.TMOSHelp is generated) to include help for
ChangeDynamicArea.

Version 4.73. Tagged as 'Kernel-4_73'

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