BSP submitted by Thomas Doerfler <td@imd.m.isar.de>:

    Finally I am through: I have found the last bugs that made RTEMS-
    4.0-beta3 start on my ppc403 board from ROM. So now the '403
    support is up to date again.

    Roughly I have added the following features:
        - support for the on-chip interrupt controller (in a separate module)
        - interrupt support for the console device
        - termios support for the console device

    ==============================================
    Since the BSP behaivour changed in some details (console no
    longer is polling, other memory layout etc) I have created a new
    BSP "helas403" rather than changing the "papyrus" BSP. The old
    "polled" console driver still sticks around in "console.c.polled"
    To get the BSP up and running, I had to create the new BSP files
    (derived from papyrus). Besides that, the following source areas
    have been changed:

    - c/src/lib/libcpu/powerpc/ppc403: changes to console driver, small
    changes to clock driver, new "ictrl" interrupt controller driver

    - c/src/exec/score/cpu/powerpc/ppc.h: some small changes
    (added ppc403 characteristics like a exception vector prefix
    register, some special register definitions). I am quite sure, they
    are compatible with the existing sources, although I did not check

    - c/src/exec/score/cpu/powerpc/cpu.c: There is one severe
    limitation in the exception entries: Due to the current code
    arrangement, the "branch absolute" to the ISR handler may only
    jump to the first 128MByte or the last 128MByte of the 4GByte
    address range. When the ppc403 is running out of ROM, the ROM
    functions are located in the last 128MByte (0xFFF00000 and up).
    These addresses were not handled correctly (sign reduced) in
    "install_raw_handler". The change I added should work on existing
    ppc BSPs aswell...

    - c/src/lib/libc/termios.c: During my tests, I added one change you
    sent me, so this patch will already be incorporated in the current
    source tree.

    There are some smaller changes, see the attached diff file.

    =========================================
    Concerning the GNU toolchain:

    I tried several tool chains. Finally I almost succeeded with

    egcs-1.0.3a with patch  egcs-1.0.3-rtems-diff-19980527

    I had to add the following lines to the egcs files. Without them
    configure complaint that the cross compiler could not generate
    executable output.
    - additional lines needed in egcs distribution in file
      gcc/config/rs6000/rtems.h:

    +++ lines start
    #undef STARTFILE_DEFAULT_SPEC
    #define STARTFILE_DEFAULT_SPEC "ecrti.o%s"

    #undef  ENDFILE_DEFAULT_SPEC
    #define ENDFILE_DEFAULT_SPEC "ecrtn.o%s"
    ++++ lines end

    As far as I have seen in the Changelog of egcs, you have recently
    sent two patches affecting the powerpc support, but they were
    added in the wrong order.... :-(

    egcs-19980628 with patch egcs-19980628-rtems-diff-19980707 does
    not work!

    I used binutils 2.9.1 with patch binutils-2.9.1-rtems-diff-19980515
     (binutils 2.8.1 does not work, internal error in gas)
    and newlib-1.8.0 with patch newlib-1.8.0-rtems-diff-19980707

    Finally I had to poke a line in the "bit" script, since, on my LINUX
    machine, the GNU make is only available as "make", not as
    "gmake"...

    For all the tools and newlib I selected configuration "powerpc-
    rtems".
