      * 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.

      * Converted to building with ObjAsm (but still a single object file using ORG). · 49836a59
      Kevin Bracey authored
      * 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.

      32-bit Kernel. · b4016e9c
      Kevin Bracey authored
      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.
