Detail:
  * Documented ADFS's and SCSIFS's CMOS use better in Hdr:CMOS.
  * Fixed typo in Hdr:NewErrors that causes asasm to emit a warning.
  * Fixed Hdr:OsBytes so that it doesn't trip up Hdr2H. Also listed hex and
    decimal OS_Byte numbers in comments for ease of reference.
  * Fixed some formatting in Hdr:CMOS and Hdr:NewErrors.

Version 2.05. Tagged as 'HdrSrc-2_05'

Detail:
  hdr/Macros - Add new SETBCD macro, to convert a number to BCD and assign it to a variable
Admin:
  Tested in OMAP3 ROM build


Version 2.04. Tagged as 'HdrSrc-2_04'

Detail:
  The result of an investigation of error number usage in filing systems -
  note that there is still a strong correlation between many of these and the
  filing system error blocks. It seemed wise to record them somewhere.
Admin:
  Tested in a Tungsten ROM build to check for name clashes.

Version 1.99. Tagged as 'HdrSrc-1_99'

Detail:
  Bugfix to Hdr:OsBytes received from Rob Sprowson

Version 1.98. Tagged as 'HdrSrc-1_98'

Detail:
  * Hdr:KEYV merged into Hdr:Keyboard - warning: anything that depends on the
    former *will break*
  * New header file, Hdr:OsBytes - for consistency with Hdr:OsWords, we'll
    keep this under the allocations system even though it's highly unlikely
    that any new allocations will be requested

  Changes from Rob Sprowson

Version 1.97. Tagged as 'HdrSrc-1_97'

Detail:
  hdr/Machine/Machine - Add new StrongARM_MSR_bug global that's TRUE when we're targeting a StrongARM-compatible machine type.
  Corrected No26bitCode and No32bitCode comments to say that it's all about whether we're supporting 26/32bit processor modes, not about whether we're targetting 26/32bit only processors
  hdr/CPU/Generic32 - Modify macros to protect against StrongARM MSR bug where appropriate.
Admin:
  Tested with IOMD softload on StrongARM RiscPC.
  Fixes issue with Maestro crashing due to MSR bug creating a stack imbalance in SoundScheduler.


Version 1.96. Tagged as 'HdrSrc-1_96'

Detail:
  Added KeyboardID_None.
  Removed sub-reason codes for International and Portable modules from
  hdr:Services - these are about to move to their respective header files.
Admin:
  Changes requested by Rob Sprowson

Version 1.95. Tagged as 'HdrSrc-1_95'

Changes provided by sprow.

Version 1.94. Tagged as 'HdrSrc-1_94'

Version 1.93. Tagged as 'HdrSrc-1_93'

Detail:
  hdr/Heap - Added definition for OS_Heap 7, HeapReason_GetAligned
Admin:
  Heap changes tested in OMAP3 & Tungsten ROMs


Version 1.92. Tagged as 'HdrSrc-1_92'

Version 1.91. Tagged as 'HdrSrc-1_91'

Version 1.90. Tagged as 'HdrSrc-1_90'

Detail:
  hdr.NewErrors: added new kernel error, requested by Rob Sprowson
  hdr.SWIs: added SWI chunks for SDIODriver and SDFS
Admin:
  Untested

Version 1.89. Tagged as 'HdrSrc-1_89'

Detail:
  Makefile - Always export Machine.All32, to provide a safe machine type for assembler-based host tools
Admin:
  Required for building ColourTrans 1.79


Version 1.88. Tagged as 'HdrSrc-1_88'

Admin:
  Submission from Willi Theiß

Version 1.87. Tagged as 'HdrSrc-1_87'

Detail:
  hdr/Macros - BYTEWS, LDROSB, STROSB & VDWS macros are now located in the kernel sources, to help keep kernel workspace private and to allow them to adapt properly to zero page relocation
Admin:
  Latest kernel sources required in order for ROM builds to function.
  This change will break the Interlace module, but everything else should hopefully be fine.


Version 1.86. Tagged as 'HdrSrc-1_86'

Detail:
  hdr/Debug - Corrected a bad use of mymrs from within the InsertTMLInitialisation macro
Admin:
  Macro compiles OK, but is untested


Version 1.85. Tagged as 'HdrSrc-1_85'

Detail:
  hdr/MEMM/VMSAv6 - Updated the system control register info to accurately reflect which bits work on ARMv6. Added missing SW, HA, FI definitions.
Admin:
  Tested on rev A2 BB-xM


Version 1.84. Tagged as 'HdrSrc-1_84'

Detail:
  hdr/Machine/Machine - Use VMSAv6 and disable unaligned memory accesses when compiling for ARM11ZF (i.e. ARMv6)
Admin:
  Tested with S3C6440 ROM build. Untested at runtime.


Version 1.83. Tagged as 'HdrSrc-1_83'

Detail:
  Suitable for ARMv6Z CPUs with VFPv2, e.g. ARM1176JZF-S
Admin:
  Required by the S3C6410 HAL

Version 1.82. Tagged as 'HdrSrc-1_82'

Detail:
  Makefile - Now uses the HALSize environment variable to select which HALSize file to export
  hdr/HALSize/64K, hdr/HALSize/96K, hdr/HALSize/128K - HALSize files for 64K, 96K, 128K HAL sizes
  hdr/MEMM/VMSAv6 - Fix the incorrect TEX definitions that were corrupting the page permissions and resulting in ROM pages being writeable.
Admin:
  Tested on rev A2 BB-xM.
  Needs latest Env folder.


Version 1.81. Tagged as 'HdrSrc-1_81'

Detail:
  Only change is "decloaking" of a couple of messages in the Wimp's private
  message block, originally for RISCOS Ltd. These are now publicly documented
  so I don't think there's any harm in revealing them in the headers.
Admin:
  Message_ToggleBackdrop is required by a Pinboard source submission.

Version 1.80. Tagged as 'HdrSrc-1_80'

Replaced LSL, LSR, etc, macros with myLSL, myLSR, etc. because the old macro
names will clash with pseudo-opcodes that ARM have introduced which in turn will
be supported by newer assemblers.

Admin: this will cause some components to fail to build, especially with the
existing toolchain. If you see these failures, simply replace any uses of these
shift macros with the renamed 'my' shift macros (which are functionally identical).

Version 1.79. Tagged as 'HdrSrc-1_79'

This component could fail during the install phase due to the INSTDIR
symbol not being defined. The Makefile will now set this to the appropriate
value if not already set.

Version 1.78. Tagged as 'HdrSrc-1_78'

Version 1.77. Tagged as 'HdrSrc-1_77'

Detail:
  This should merge all of the Cortex HdrSrc changes into the trunk, so we don't have to worry about OMAP builds breaking each time the trunk HdrSrc changes
Admin:
  Untested!


Version 1.76. Tagged as 'HdrSrc-1_76'

Finally... :)

Version 1.75. Tagged as 'HdrSrc-1_75'

* Added VFPSupport SWI definition.
* Added some new industry standard file types.
* Added some new sprite errors.

Version 1.74. Tagged as 'HdrSrc-1_74'

Detail:
  Add two new macros to allow the loading of (un)signed halfwords from an array of halfwords, i.e. LDR(S)H $dest, [$array, $index, LSL #1]
  These shared macros help tidy up some code in the International & FontManager modules, code which needed to be changed to get the NoUnaligned build option working correctly.
Admin:
  Tested on rev C2 beagleboard, with and without NoUnaligned. Macros are untested for the situation where unaligned loads are supported but LDRH is not; however the code produced should be identical to the code that the International & FontManager modules originally used.


Version 1.73. Tagged as 'HdrSrc-1_73'

Detail:
  * LD macro updated to know about LDRH and LDRD instructions
  * LDW macro updated: safe to use on last word of a page; no longer enforces
    relative order of temporary registers; uses unaligned loads when possible;
    uses 1 fewer instructions if ARMv6 compatibility is not required;
    scheduled for XScale and Cortex-A8
Admin:
  Tested with BASIC softload on RISC OS 5.12 Iyonix.
  Fixes bug #220


Version 1.72. Tagged as 'HdrSrc-1_72'

Detail:
  These macros allow easy access to registers pushed on the stack during the Entry macro.
This is simpler than the previous method of "LDR     r1, [sp, #Proc_LocalStack + 1*4]" because the new macros will calculate the correct offset even if non-continuous regs are used, and will also trap attempts to access regs that weren't pushed onto the stack.

  The FRAMSTR macro can be used to alter the values that will be returned on EXIT.
Admin:
  Tested by looking at produced code in Zap
Notes:
  Changes by James Lampard.

Version 1.71. Tagged as 'HdrSrc-1_71'

Admin:
  This is only intended for use when building the disc image for the C/C++ CD.

Version 1.70. Tagged as 'HdrSrc-1_70'

Detail:
  For use when building binaries which must run on a wide range of ARM
  architectures - typically used by disc builds rather than rom builds.
  Use Machine=All to target all machines, or Machine=All32 for any
  architecture from v3 (ARM600) upwards.
Admin:
  Tested in a BuildHost build.

Version 1.69. Tagged as 'HdrSrc-1_69'

Detail:
  Added NoUnaligned flag to Hdr:Machine:Machine to aid with debugging of
  unaligned loads.
Admin:
  Various other modules will shortly start checking this flag to decide
  whether to enable unaligned loads on ARMv6/v7.

Since I've only just committed 1.68, I'll reapply the tag at this revision.

Version 1.68. Not tagged

Detail:
  Added definitions of new CPSR bits and moitor mode in newer ARM cores
Admin:
  Used in OMAP3 builds, but needs to be on the trunk because the Debugger
  module will use the definitions in other builds.

Version 1.68. Tagged as 'HdrSrc-1_68'

Detail:
  Didn't previously interact with other standard RISC OS headers, especially
  Hdr:ListOpts
Admin:
  Has now been used successfully in an (as-yet unreleased) build of Squash
  to add compatibility with ARMv6

Version 1.67. Tagged as 'HdrSrc-1_67'
