      Detail:
        "Podule" number now displayed again in *ROMModule output - flag
           preservation issue caused it to disappear in 5.23.
        *Eval output no longer misses its trailing space, neither do "Podule" or
          "Extn ROM" in *ROMModules output.
        Heap manager now works again in non-SVC modes.
        Exception dump now contains faked up 26-bit PC+PSR lookalike.

        Assembled.

      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.

      Removed redundant MACFROMNVRAM introduced in Kernel 5.09. · 3e7e3a11
      Paul Skirrow authored
      Detail:
        MACFROMNVRAM was intended to force the Kernel to fetch the MAC
        address from NVRAM for Customer F 5. In practice it is not needed
        as its main purpose was to avoid getting the MAC address from
        the RawMachineID but this will not happen in Customer F 5 as
        RawMachineID will not be set.
      
      Admin:
        Not tested.
        MACFROMNVRAM will be removed from HdrSrc.

      Added OS_ReadSysInfo 6, 7 and 8 from Ursula branch. · b85d7d81
      Stewart Brodie authored
        Ensured that M_Phoebe builds set UtilityModule version to 4.00
      Detail:
        The softload utility relies on the existence of the extra reason codes
          to OS_ReadSysInfo introduced in Ursula.  The main kernel now supports
          these too (they are simply interfaces to read kernel capabilities and
          configuration - eg. addresses and sizes of UND and SVC mode stacks)
        Avoid OS_ReadSysInfo 9 - ROL have used it for reading the ROM personality
          information (and it's not in our kernel)
        Added some of the new macros into Copro15ops required by the ABT dump
          area code (returned by OS_ReadSysInfo 7) and added the code into ARM600
          to store abort information there.
      Admin:
        Required by softload utility for Ursula builds.
        Tested on Risc PC.

      Kernel reads Ethernet MAC address from NVRAM (and nowhere else) if · 6760ce30
      Paul Skirrow authored
        MACFROMNVRAM is set. This is set in HdrSrc for Customer F machines.
      
      Detail:
        If MACFROMNVRAM is TRUE then OS_ReadSysInfo 4 will read the Ethernet MAC
        Address from bytes 0-13 of the NVRAM area, instead of trying to read it
        from anywhere else. (14 bytes are ysed to store 2 copies and 2
        checksums).
      
        This is intended for use with a 24LC128 device (which has no OTP area
        and no clock).
      
        Note that these are physical addresses within the device. Logical
        addresses &F0-&FF map to physical addresses &00-&0F.
      
        A SetMac utility is provided in Customer F 5 !Boot.Utils to enable the MAC
        address to be programmed for prototypes and development machines.
      
        Since it is dangerous to rely on the NVRAM to hold our MAC address when
        it is not protected in any way, we store two copies of it, each with
        their own checksum. At present only the first copy is used, but the
        plan is to check both copies and both checksums.
      
      Admin:
        This version of the Kernel needs Programmer/HdrSrc v0.68 or later.
      
        If MACFROMNVRAM is enabled, ensure that the MACADDRESS tag in the
        NVRAM file is set to point at &F0 and that MACADDRESSCHECKSUM
        is set to point at &F6. Both should have options L and P to ensure
        they are protected from NVRAM resets and other writes.

      Kevin Bracey authored
      OS_ReadSysInfo 2 now reports whether the IIC bus is fast (in bit 24 of R2), and whether I/O clocks should be stopped when idling the processor (bit 25).
      
      OS_Byte 19 is a bit more careful in its use of Portable_Idle - an edge case
      where the vsync interrupt was already pending now returns immediately.

      RCMM changes made the Kernel not report the type of I/O chip fitted correctly. · 6142809f
      Kevin Bracey authored
      This has been fixed. In addition, SMC669 and UMC669 chips are reported as
      a different chip configuration by OS_ReadSysInfo 3 (values 4 and 5
      respectively).
      A few assertions added to catch the remaining cases where the RCMM stuff
      won't work - those cases will involve a bit more reordering of hardware
      initialisation.

      ROM speed not taken from the Machine header file. POST can now exist in a... · 417410eb
      Neil Turton authored
      ROM speed not taken from the Machine header file.  POST can now exist in a softloaded OS, since it searches for a zero word in the ROM instead of using one within the POST when trying to communicate with the POST adapter (the zero word must be in ROM).  Fixed to build on non-chrontel STB/NC products.  Lots of duplicate code merged in
      
      MemSize.  MemSize copes better with the softload case, and is less
      willing to use the region the OS occupies as video memory, or
      page tables.  POST is now ON (memory tests disabled).
      OS_ReadSysInfo 4 now uses the NVRAM module to access the ethernet
      address in NVRAM/CMOS, so that the availability/location of the
      MAC address can be changed.  CMOS location 0 is now unprotected on
      STB/NC products to try to stop people poking the hardware directly.
      Fixed a CMOS resetting problem on STBs where the value expected in a
      location was different from the value written on a CMOS reset, so the
      CMOS would be reset every time...
