Detail:
  Makefile rule was missing for VideoDevice header export, preventing it from being exported
Admin:
  Tested on rev C2 beagleboard. (No, really, I mean it this time!)


Version 5.35, 4.79.2.98.2.17. Tagged as 'Kernel-5_35-4_79_2_98_2_17'

Detail:
  hdr/VideoDevice, Makefile - Add initial version of header for video HAL devices
  hdr/HALDevice - Add device IDs for OMAP3 DMA & video devices.
Admin:
  Tested on rev C2 beagleboard


Version 5.35, 4.79.2.98.2.16. Tagged as 'Kernel-5_35-4_79_2_98_2_16'

Detail:
  HAL kernels (on the Cortex branch at least) now support HALDevice-based RTCs. If the kernels own RTC code is disabled or fails to detect an RTC, then after HAL_InitDevices is called the HALDevice list will be scanned for any HAL-resident RTC devices.
  Additionally, the RTCSupport flag (in Hdr:Machine.Machine), which was previously TRUE for all HAL kernels, can now be set to FALSE in HAL kernels to disable the kernels own IIC RTC code. This allows the unwanted legacy RTC code to be disabled for machines which are known to use HAL RTCs instead.
  hdr/RTCDevice - new header describing data structures used for HAL RTC device
  hdr/HALDevice - added RTCDevice device type, IIC serial bus type
  hdr/KernelWS - upgraded RTCFitted from a 1 byte field to 4 byte. It now stores either a null value (for no RTC), a value <2048 for an IIC RTC address, or a value >= 2048 for a RTCDevice ptr
  Makefile - added header export of hdr/RTCDevice
  s/GetAll - include hdr/RTCDevice
  s/NewReset - initialise HAL RTC after HAL_InitDevices if required
  s/PMF/i2cutils, s/PMF/osinit, s/PMF/osword - modifications to allow use of HAL RTC (and disallow use of builtin IIC RTC)

Version 5.35, 4.79.2.98.2.11. Tagged as 'Kernel-5_35-4_79_2_98_2_11'

Detail:
  s.PMF.i2cutils line 454: this LDR of byte values was harmless (bits 8
    upwards are discarded later) but slower than an LDRB on ARMv6 or later.
  s.PMF.i2cutils line 556: should have loaded RTCFitted using LDRB. Looks
    like effect would have been to reduce utilisation of CMOS cache.
  s.vdu.vduswis line 1500: mistakenly accessing ExternalFramestore using LDR.
    I don't think the intention was to prevent the screen DA being resized
    while screen memory was claimed, but that was the effect.
  s.vdu.vduwrch line 3106: this LDR of a 1-byte variable was harmless (only
    used for testing bit 4) but slower than an LDRB on ARMv6 or later.
  CPU version is no longer specified in the makefile - it's better to inherit
  it from the build environment now that we actually set it appropriately.
Admin:
  Built and briefly tested.

Version 5.35, 4.79.2.98.2.9. Tagged as 'Kernel-5_35-4_79_2_98_2_9'

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, 4.79.2.48. 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
