hdr/AHCIDevice:
  Remove this, since it clashes with the (differing API version number) copy exported by SATADriver. Post merging the Kernel back to the trunk the newer file datestamp has meant the wrong one gets exported during any ROM build which includes both components. Since the Kernel doesn't need AHCIDevice itself, it is left to the respective client (SATADriver or AHCIDriver in this case) to export them.
hdr/ModHand:
  Resolve the longstanding clash of Module_Title with the same named symbol that CMHG uses. There are very few assembler needing to look at the module header (Kernel, FileCore, Debugger, Podule) directly, but every C module which uses CMHG and wants one of the ModHandReason values ends up with a duplicate define.
  Obsolete Arthur era Module_LoadAddr value.
ArthurSWIs.s/MoreComms.s/NewReset.s/SWINaming.s/SysComms.s/Utility.s:
  Module_Title->Module_TitleStr.
ModHand.s:
  Module_Title->Module_TitleStr.
  Recode Module_LoadAddr using the file type from Hdr:FileTypes.
GetAlls.s:
  Drop unused NVRAM and PortMan headers. Add Hdr:FileTypes.

  Identical binary to previous revision for IOMD & Raspberry Pi builds


Version 5.51. Tagged as 'Kernel-5_51'

Variously the call to TranslateError was either followed (outside the switch) by an unnecessary SETV, or missing SETV for the non international case.
Added DMA controller HAL device for IOMD.

Version 5.35, 4.79.2.174. Tagged as 'Kernel-5_35-4_79_2_174'

The kernel already looks after all other aspects of the ARM CPU, so can look after the cache control command too.
 HelpStrs.s:New tokens for help and syntax
 CmdHelp.s:UK help and syntax
 Arthur3.s:Tables updates for *CONFIGURE/STATUS, lined some stuff up, default error text sync'd with Hdr:NewErrors
 MoreComms.s:Parsing and doing of *CACHE
 Utility.s:Hashing table updated for *CACHE
Other minor changes
 hdr/Options:Bring 'MosVer' into the private header
 hdr/RISCOS:aasm aliases for SP removed, MainVars and MosVer made private, added definition of the start of application space
 HeapMan.s:Use of GRAB changed to Pull
 Offset of TutuCMOS changed for more informative PrintSoundCMOS
 PMF/osbyte.s:Use OsBytes header file in place of MainVars

Version 5.35, 4.79.2.151. Tagged as 'Kernel-5_35-4_79_2_151'

Detail:
  hdr/ARMops - Reserve OS_PlatformFeatures 0 bit 20 for indicating whether high processor vectors are in use
  s/Kernel - Add local definitions of BYTEWS, LDROSB, STROSB, VDWS macros (previously in Hdr:Macros)
  s/MoreComms - Fix potential buffer overflow when filling error buffer (although GSTrans shouldn't overflow the buffer in the first place?)
  s/Arthur2 - GSRead number detection fix
  s/ArthurSWIs - Updated OS_ReadUnsigned to support reading 64bit numbers
  Docs/ReadUnsigned - Docs for the updated OS_ReadUnsigned interface
Admin:
  Untested!
  Needs HdrSrc 1.86


Version 5.35, 4.79.2.120. Tagged as 'Kernel-5_35-4_79_2_120'

Detail:

Admin:
  Tested on rev A2 BB-xM
  Requires HdrSrc 1.86


Version 5.35, 4.79.2.98.2.46. Tagged as 'Kernel-5_35-4_79_2_98_2_46'

Look for LongCommandLine flag, command line size currently
set at 1k.
For HAL/32bit builds, the kernel buffer space is at high
(top bit set) address, which may break some code using signed
comparisons. So *beware* that there may be some latent
bugs in old kernel code using these buffers, not yet found.
One such bug, in s.Arthur2 found and fixed.
Tested moderately on ARM9 desktop build.
Lovely to reimplement things I did two and half years ago.

Version 5.35, 4.79.2.37. Tagged as 'Kernel-5_35-4_79_2_37'

* 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:
  "Podule" number now displayed again in *ROMModule output - flag
     preservation issue caused it to disappear in 5.23.
  *Eval output no longer misses its trailing space, neither do "Podule" or
    "Extn ROM" in *ROMModules output.
  Heap manager now works again in non-SVC modes.
  Exception dump now contains faked up 26-bit PC+PSR lookalike.
Admin:
  Assembled.

Details:
  The Kernel will now compile to produce a pure 32-bit system if No26bitCode is
  set to TRUE.
  If No26bitCode is FALSE, then the Kernel will be a standard 26-bit Kernel,
  although some internal changes have taken place to minimise compile
  switches between the two cases. See Docs.32bit for more technical info.

  The hardest part was the flood-fill...

Other changes:
  Pointer shape changes now take place on the next VSync, rather than actually
  WAITING for the VSync. Turning the Hourglass on shouldn't slow your machine
  down by 5% now :)

  Lots of really crusty pre-IOMD code removed.

Admin:
  Tested in 32 and 26-bit forms in a limited desktop build. Basically, this
  will need to see a lot of use to iron out difficulties. I'd like anyone who
  has a non-frozen project to at least attempt using this Kernel.

Version 5.23. Tagged as 'Kernel-5_23'

Detail:
  The code for *ROMModules uses OS_PrettyPrint, which seems unconcerned
    by such trivial things as leading spaces, which accounts for the
    misaligned output.  The code now starts by using ASCII 31 (hard
    space for OS_PrettyPrint's purposes) as the leading indent character
    to avoid confusion.
Admin:
  Tested on desktop build in both command-line and TaskWindows.

Version 5.20. Tagged as 'Kernel-5_20'

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