      Add VMSAv6 MMU support, fixes to allow booting on beagleboard · 3d1317e7
      Jeffrey Lee authored 
      Detail:
  s/ARM600 - fix to SyncCodeAreasRange to correctly read cache line length for WB_CR7_Lx caches
  s/ARMops - Cortex cache handling fixes. Enable L2 cache for Cortex.
  s/ChangeDyn - VMSAv6 support in AllocateBackingLevel2
  s/HAL - Improve RISCOS_InitARM to set/clear correct CP15 flags for ARMv6/v7. VMSAv6 support in code to generate initial page tables.
  s/NewReset - Extra DebugTX calls during OS startup. Disable pre-HAL Processor_Type for HAL builds.
  s/VMSAv6 - Main VMSAv6 MMU code - stripped down version of s/ARM600 with support for basic VMSAv6 features.
  hdr/Options - Use VMSAv6 MMU code, not ARM600. Disable ARM6support since current VMSAv6 code will conflict with it.
Admin:
  Tested basic OS functionality under qemu-omap3 and revision B6 beagleboard.

      Add support for Cortex cache type. Extend ARM_Analyse to, where appropriate, use CPU feature registers to identify CPU capabilities.

Detail:
  s/ARMops - Support for Cortex multi-level cache (CT_ctype_WB_CR7_Lx). New ARM_Analyse_Fancy to identify CPU capabilities using feature registers.
  s/HAL - Modify pre-ARMop cache code to handle Cortex-syle caches.
  s/MemInfo - Replace ARM_flush_TLB macro call with appropriate ARMop to provide Cortex compatability
  hdr/ARMops - Update list of ARM architectures
  hdr/CoPro15ops - Deprecate ARM_flush_* macros for HAL kernels, as they are no longer capable of flushing all cache types. ARMops should be used instead.
  hdr/KernelWS - Add storage space for multi-level cache properties required for new cache cleaning code.
Admin:
  Tested under qemu-omap3. Still unable to verify on real hardware due to lack of appropriate MMU code. However new OMAP3 HAL code that uses similar cache management functions appears to work fine on real hardware.

      Bugfix and header change. · 9a6346d8
      Ben Avison authored 
      Detail:
  * I noticed in passing that the default exception handlers were broken for
    non-IOMD machines if the exception was raised in FIQ mode - unless you
    had a very large application slot, then the machine would lock up. Now
    properly HAL-ised.
  * Added a new event number, allocated for PRISM use back in June.

  Not tested. However, it can't make the situation any worse!

      Change to calling conditions of UnthreadV. · 5e89ff87
      Ben Avison authored 
      Detail:
  Previously, UnthreadV was only called when the IRQsema chain was empty, the
  link for the just-completed interrupt having just been removed. However,
  the information in the link is necessary to allow OS_Heap to be called from
  UnthreadV context, and patching up IRQsema within the UnthreadV handler
  prevents the implementation of a prioritised threading scheme. As a result,
  we must call UnthreadV every time the interrupt dispatch unthreads, and
  leave it up to the UnthreadV handler to distinguish between return to
  thread context and return from a nested interrupt handler.
Admin:
  Will require some sort of patch to enable heap-safe prioritised threading
  on RISC OS-STB 5.0.0 or RISC OS 5.07, the only two released OSes with the
  previous UnthreadV behaviour.

      fix for invalid cmos checksum computation on iyonix new version date for 5.07 · 83827e89
      John Ballance authored 
      Detail:
   CheckSumBlock called IIC_OpV to checksum byte 0 of CMOS, but read back the
   resultant checksum from the wrong offset (#20.. new R1 value)..  now
   corrected to #24 as the correct offset (approx line 997).

      Bugfixes to OS_Bytes 13 and 14. · 799120d5
      Ben Avison authored 
      Detail:
  Event numbers greater than 31 are possible, it's just that OS_GenerateEvent
  doesn't bother cheking the event semaphores for them. However, the value
  returned in R1 from these OS_Bytes always indicated that such events were
  disabled. This suggests that OS_GenerateEvent was not always so, but the
  initials in comments there suggest the change was about RISC OS 3.0.
  The OS_Bytes now correctly reflect OS_GenerateEvent behaviour.
  Another bug fix is that once the event semaphores had saturated at 255,
  OS_Byte 13 was still happy to decrement the semaphore, so for example 256
  enables followed by 255 disables would have disabled the event.

      Added UnthreadV (vector &2B). Called near the end of despatch of the outermost interrupt, in IRQ32/26 mode with IRQs disabled, just before transient and non-transient callback checking is performed. Suitable for implementing a CBAI replacement.

      * HAL can choose to limit amount of screen memory to allocate · 0f6941a8
      Kevin Bracey authored 
        [Not fully implemented - for now leaves at least 16MB free if only
  one RAM area; was 1MB].
* Added HAL_USBControllerInfo, HAL_MonitorLeadID and HAL_Video_Render.
* Added HAL->OS call OS_IICOpV.
* OS_MMUControl now allows independent control of I and C bits.
* Added facility to deactivate keyboard debounce (magic word "NoKd" in
  R2 in KeyV 0).
* Fixed problem with RAM amounts not a multiple of 4MB.
* Supremacy bit (in VDU 19) now sets all 8 bits of supremacy.
* Added PaletteV 14 (reads gamma tables).
* Added Supremacy transfer functions (like gamma correction, but for
  supremacy). Allows easy global supremacy effects in a mode-independent
  fashion. Controlled with PaletteV 15,16.
* Added modes 50-53 (320x240, 1,2,4,8bpp). Intended for small LCD.
* Added 13.5kHz versions of TV modes (selected by Hdr:Machine).
* Upped desktop version to 5.06.
