      Review of Internation switch · d58ce177
      Robert Sprowson authored
      Variously the call to TranslateError was either followed (outside the switch) by an unnecessary SETV, or missing SETV for the non international case.
      Added DMA controller HAL device for IOMD.

      Detail:
        s/ARMops - Added branch predictor maintenance to WB_CR7_LDa ARMops. If the entire instruction cache is being invalidated then the branch predictors will be invalidated for us, but for ranged invalidation we need to handle it ourselves.

      Some tweaks ahead of an RPi code freeze. · 276a05dd
      Steve Revill authored
      Default CMOS tweaks now apply for the RPi hardware. Was missed in
      the previous commit.
      
      You can now build the Kernel without the ROM debug output stuff
      that's enabled for odd-numbered builds, by passing FREEZE_DEV_REL=TRUE
      into the makefile. For example, in the Components file, you'd add:
      
        -options FREEZE_DEV_REL=TRUE
      
      onto the Kernel line.

      Actually pay attention to configured cache preferences · ee2fa7bc
      Robert Sprowson authored
      The kernel recently took back ownership of the *CACHE command and it's configure counterpart, but wasn't reading the CMOS value on startup.
      Spotted while looking at bus transactions on IOMD, and wondering where they all are, then realising it's all running from the cache.

      Fix addresses sent to GraphicsV_SetDMAAddress when external framestore in use. Add ID for BCM2835 VDU HAL device.
      
      Detail:
        hdr/KernelWS, s/vdu/vdudriver, s/vdu/vduwrch - Fixed wrong addresses being sent to GraphicsV_SetDMAAddress when an external framestore is in use. Previously VideoPhysAddr was being treated as if it was the base of screen memory, but that's only the case if an internal framestore is in use. Since VideoPhysAddr is part of PhysRamTable it's not possible to change it to point to an external framestore, so a new workspace variable, TrueVideoPhysAddr, is used instead.

      Sort out SetBorder · fe354937
      Robert Sprowson authored
      NewReset.s:
      The one remaining use of SetBorder was to denote the user asked for and got a CMOS reset, which in the HAL case emitted a warning because setting the border is potentially complicated/slow.
      To solve this, the reset is noted and replaces the normal RISC OS banner with a warning message. The behaviour and text for this comes from the BBC Master, though the escape key is used in place of break since a reset isn't actually needed.
      Moved the unused cputable inside its corresponding switch.
      Two occurrences of WriteS_Translated would have executed the message in the V=1 case.
      KernelWS/Resources:
      Flag added to workspace, translation added to messages files.
      Heapman.s:
      Commented out use of SetBorder removed.
      Kernel.s:
      SetBorder macro removed.
      Middle.s:
      Switched out use of SetBorder removed.
      Super1.s:
      Conditional WriteS_Translated would try to execute the message in the opposite condition case.

      Fixed cache detection code · 115e6d35
      Ben Avison authored
      Detail:
        The cache details were previously fixed in a look-up table based upon the
        CPU as determined from the Main ID register for "fancy" ARMv6 CPUs (that is,
        ARMv6K, ARMv6Z, ARMv6T2). So the details for the S3C6410 were being used
        for all ARM1176JZF-S CPUs, which isn't correct for the BCM2835, which has
        the same CPU. Adrian's original stopgap solution was to override the
        settings with a bunch of MOV instructions, which had the effect of making
        the kernel useless on any other CPU. Now the details are read from the ARM
        cache type register for fancy ARMv6 CPUs. This necessitated adding support
        for an extra cache type: writeback, with cache cleaning using R7, and cache
        lockdown format C. Since we don't actually do cache lockdown, this follows
        the same code path as cache lockdown type A, which was originally written
        for ARM9 CPUs.
