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

kernel now attempts to substitute video mode numbers in face of h/w with limited bits-per-pixel support (not tested yet)

HAL_API document added - early draft only, of interest to those
writing or modifying HALs for new h/w
ARMop_API document added - early draft only, of interest only
to those modifying kernel to support new ARM cores
*** polite comments on HAL_API welcome ***

Version 5.35, 4.79.2.15. Tagged as 'Kernel-5_35-4_79_2_15'

partial video changes for kernel/HAL split near-HAL code for VIDC/IOMD in vdu.vduhint briefly tested in Ursula desktop build still some kernel workspace dependency in near-HAL code

Version 5.35, 4.79.2.3. Tagged as 'Kernel-5_35-4_79_2_3'

* 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'

Had one of those weekend brainstorms - managed to speed up SWI despatcher _and_ add Thumb support to it.

Fixed OS_BreakPt - was confused by PC/PSR split.

Version 5.24. Not tagged

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'

* Wasn't allowing writes to most of EEPROM.
* Old prototype OS_SetTime SWI code removed.
* MPEGPoduleNTSCNotPALMask option support removed to simplify things a bit.
* Now can cope with a system with a PAL/NTSC link, but no monitor detect line.
* Default PAL & NTSC modes now always 12 & 46 respectively.
* Kernel now knows about monitor type 8 (NTSC) - modes 44-46 (640x200) are
  available.
* STB/NC CMOS test removed from POST pending further investigation.

Version 4.90. Tagged as 'Kernel-4_90'

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