      Assorted kernel fixes for ARMv6/ARMv7 · ca8f36f5
      Jeffrey Lee authored
      Detail:
        s/ARMops - Fix IMB_Range_WB_CR7_Lx to clean the correct number of cache lines
        s/HAL - Change CP15 control register flags so unaligned loads are enabled on ARMv6 (to simplify support for ARMv7 where unaligned loads are always enabled, and to match the behaviour expected by the example code in Hdr:CPU.Arch)
        s/AMBControl/memmap - Make AMB_LazyFixUp use the correct L2PT protection flags depending on ARM600/VMSAv6 MMU model. Also guard against problems caused by future L2PT flag changes.
        s/vdu/vdugrafj - Fix previously undiscovered 32bit incompatability in GetSprite (OS_SpriteOp 14/16)

      * 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.

        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'
