Version 5.35, 4.79.2.7. Tagged as 'Kernel-5_35-4_79_2_7'

Version 5.35, 4.79.2.5. Tagged as 'Kernel-5_35-4_79_2_5'

* 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'

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:
  Most of the centisecond timers were incremented very early in the Timer0
  interrupt routine, but MetroGnome was incremented after we had called
  TickerV. Routines on TickerV are allowed to enable interrupts, so any
  interrupt routines that use OS_ReadMonotonicTime and IRQRQA are unable to
  accurately determine if the monotonic time is one tick out-of-date or not.
  MetroGnome is now incremented with the other timers.
Admin:
  Tested with the timer code in STB-400 MPEGDriver.

Version 5.22. Tagged as 'Kernel-5_22'

Version 5.06. Tagged as 'Kernel-5_06'

Power down A to D convertors on reset.

Version 5.05. Tagged as 'Kernel-5_05'

This has been fixed. In addition, SMC669 and UMC669 chips are reported as
a different chip configuration by OS_ReadSysInfo 3 (values 4 and 5
respectively).
A few assertions added to catch the remaining cases where the RCMM stuff
won't work - those cases will involve a bit more reordering of hardware
initialisation.

Version 5.00. Tagged as 'Kernel-5_00'

Right arrow on a remote also acts as Delete.

Version 4.98. Tagged as 'Kernel-4_98'

Version 4.95. Tagged as 'Kernel-4_95'

Now calls XPortable_Idle, not Portable_Idle in key-wait code.
Calls Portable_Idle in OS_Byte 19.

Version 4.94. Tagged as 'Kernel-4_94'

Kernel now uses PortManager to set TV_Mode GPIO line, and updates it on every mode change, rather than doing it once based on the monitor lead ID.

Requires PortManager, and required if PortManager is present.

Version 4.92. Tagged as 'Kernel-4_92'

Version 4.91. Tagged as 'Kernel-4_91'

* 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'

Version 4.70. Tagged as 'Kernel-4_70'

ROM speed not taken from the Machine header file.  POST can now exist in a softloaded OS, since it searches for a zero word in the ROM instead of using one within the POST when trying to communicate with the POST adapter (the zero word must be in ROM).  Fixed to build on non-chrontel STB/NC products.  Lots of duplicate code merged in

MemSize.  MemSize copes better with the softload case, and is less
willing to use the region the OS occupies as video memory, or
page tables.  POST is now ON (memory tests disabled).
OS_ReadSysInfo 4 now uses the NVRAM module to access the ethernet
address in NVRAM/CMOS, so that the availability/location of the
MAC address can be changed.  CMOS location 0 is now unprotected on
STB/NC products to try to stop people poking the hardware directly.
Fixed a CMOS resetting problem on STBs where the value expected in a
location was different from the value written on a CMOS reset, so the
CMOS would be reset every time...

Version 4.69. Tagged as 'Kernel-4_69'

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

Version 4.64. Tagged as 'Kernel-4_64'

Not fully tested on all hardware permutations.
