2008-11-03      Till Straumann <strauman@slac.stanford.edu>

        * shared/startup/pretaskinghook.c, shared/startup/sbrk.c:
        Fixed PR#1335.

2008-10-02      Sebastian Huber <sebastian.huber@embedded-brains.de>

        * shared/clock/clock.c: Update for status-checks.h changes.

2008-10-02      Joel Sherrill <joel.sherrill@oarcorp.com>

        * shared/startup/bspgetworkarea.c: Change size_t to ssize_t on
        bsp_get_work_area(). On 16-bit architectures, size_t can be 16-bits
        which would limit the work area to 64K.

2008-09-22      Joel Sherrill <joel.sherrill@oarcorp.com>

        * shared/console/inch.c, shared/startup/panic.c: Use standardized
        bsp_cleanup() which can optionally print a message, poll for user to
        press key, and call bsp_reset(). Using this eliminates the various
        bsp_cleanup() implementations which had their own implementation and
        variety of string constants.
        * shared/console/bspreset.c: New file.
        * shared/console/reboot.c: Removed.

2008-09-19      Joel Sherrill <joel.sherrill@oarcorp.com>

        * shared/startup/bspgetworkarea.c, shared/startup/sbrk.c: Remove
        warnings by switching to uintptr_t.

2008-09-19      Joel Sherrill <joel.sherrill@oarcorp.com>

        * shared/start/start.S, shared/startup/bspgetworkarea.c,
        shared/startup/bspstart.c, shared/startup/linkcmds: Modifications
        which reflect those tested on psim. Hopefully they work on all
        boards. The initialization stack is explicitly declared in the
        linkcmds memory layout rather than magic math.

2008-09-16      Joel Sherrill <joel.sherrill@oarcorp.com>

        * shared/include/nvram.h: Fix typo.

2008-09-16      Joel Sherrill <joel.sherrill@oarcorp.com>

        * shared/clock/clock.c: Remove unnecessary includes of
        rtems/libcsupport.h and rtems/libio.h.

2008-09-15      Joel Sherrill <joel.sherrill@oarcorp.com>

        * shared/startup/bspstart.c, shared/startup/pretaskinghook.c: Add use
        of bsp_get_work_area() in its own file and rely on BSP Framework to
        perform more initialization.
        * shared/startup/bspgetworkarea.c: New file.

2008-09-10      Joel Sherrill <joel.sherrill@oarcorp.com>

        * shared/startup/bspstart.c: Review of all bsp_cleanup()
        implementations. In this phase, all prototypes were removed from
        bsp.h and empty implementations were removed and made to use the
        shared stub.

2008-09-08      Joel Sherrill <joel.sherrill@oarcorp.com>

        * acinclude.m4: Add tqm8xx.

2008-09-08      Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>

        * tqm8xx: New BSP.

2008-09-06      Ralf Corsépius <ralf.corsepius@rtems.org>

        * shared/irq/irq.c: Convert to "bool".

2008-09-05      Joel Sherrill <joel.sherrill@OARcorp.com>

        * shared/clock/clock.c: The Shared Memory Driver no longer requires the
        special IOCTL in Clock_control. This was a hack which has existed
        since before the Classic API Timer Manager was implemented. All
        implementations of and references to Clock_control were removed.

2008-09-05      Ralf Corsépius <ralf.corsepius@rtems.org>

        * shared/console/inch.c: Convert to "bool".

2008-08-28      Till Straumann <strauman@slac.stanford.edu>

        * shared/vme/vme_universe.c: added implementation for
        BSP_VMEResetBus().

2008-08-20      Ralf Corsépius <ralf.corsepius@rtems.org>

        * shared/flash/flash.c, shared/irq/irq_init.c: Add missing
        prototypes.
        * shared/showbats.c, shared/console/inch.c, shared/irq/irq_init.c,
        shared/pci/detect_raven_bridge.c, shared/startup/bspstart.c,
        shared/startup/zerobss.c, shared/vme/vmeconfig.c,
        startup/exit.c: Add missing prototypes.

2008-08-19      Sebastian Huber <sebastian.huber@embedded-brains.de>

        * shared/clock/clock.c: Fixed warnings.

2008-07-18      Sebastian Huber <sebastian.huber@embedded-brains.de>

        * shared/clock/clock.c: Update due to powerpc-utilty.h changes.

2008-07-14      Sebastian Huber <sebastian.huber@embedded-brains.de>

        * mpc55xxevb: New BSP.

2008-07-14      Thomas Doefler <Thomas.Doerfler@embedded-brains.de>
        * haleakala: added new BSP

2008-07-11      Sebastian Huber <sebastian.huber@embedded-brains.de>

        * ep1a/startup/bspstart.c, mvme3100/startup/bspstart.c,
        mvme5500/startup/bspstart.c, psim/startup/bspstart.c,
        shared/startup/bspstart.c: The usage of SPRG0 as changed.  It is now
        used to store the interrupt disable mask.  See bootcard.c and
        ppc_exc_initialize() for default initialization.

        Update to new exception initialization routine ppc_exc_initialize().
        The exception low level code has changed, see libcpu/powerpc/ChangeLog.

        * gen5200/startup/bspstart.c, mbx8xx/startup/bspstart.c,
        mpc8260ads/startup/bspstart.c, ss555/startup/bspstart.c,
        virtex/startup/bspstart.c: The usage of SPRG0 as changed.  It is now
        used to store the interrupt disable mask.  See bootcard.c for default
        initialization.

2008-07-10      Till Straumann <strauman@slac.stanford.edu>

        * shared/flash/spansionFlash.c: removed "m" memory
        operands.

2008-07-09      Sebastian Huber <sebastian.huber@embedded-brains.de>

        * shared/clock/clock.c: Alternative clock driver.  Uses exception handler
        directly.  Supports special variants for Book E and e300 cores.  For
        standard decrementer CPUs the new decrementer value is calculated with
        reference to a time base so that a time drift is avoided.

2008-07-01      Joel Sherrill <joel.sherrill@oarcorp.com>

        * shared/uboot_getenv.c: New file.

2008-06-02      Joel Sherrill <joel.sherrill@oarcorp.com>

        * shared/startup/panic.c: Convention calls for leading underscore on
        private RTEMS variables.

2008-05-23      Till Straumann <strauman@slac.stanford.edu>

        * shared/startup/pretaskinghook.c: removed declaration
        of BSP_vme_config() (which is already declared in
        <bsp/VME.h>. Removed test for NULL-ness of BSP_vme_config;
        gcc doesn't seem to understand that the linker may 
        define this to be NULL... Silences a compiler warning
        (and users can always provide an empty routine).

2008-05-22      Till Straumann <strauman@slac.stanford.edu>

        * shared/startup/linkcmds, shared/startup/zerobss.c:
        introduced '__bss_end'; assuming that __rtems_end
        coincides with the end of .bss for the purpose of
        zeroing .bss is very dangerous.

2008-05-22      Joel Sherrill <joel.sherrill@OARcorp.com>

        * shared/console/console.c: Fix typo.

2008-05-22      Joel Sherrill <joel.sherrill@oarcorp.com>

        * shared/console/console.c: Remove explicit switch and call
        termios_baud_to_number().

2008-05-15      Joel Sherrill <joel.sherrill@OARcorp.com>

        * shared/startup/pretaskinghook.c: Add capability for bootcard.c BSP
        Initialization Framework to ask the BSP where it has memory for the
        RTEMS Workspace and C Program Heap. These collectively are referred
        to as work area. If the BSP supports this, then it does not have to
        include code to split the available memory between the two areas.
        This reduces the amount of code in the BSP specific bspstart.c file.
        Additionally, the shared framework can initialize the C Library, call
        rtems_debug_enable(), and dirty the work area memory. Until most/all
        BSPs support this new capability, if the BSP supports this, it should
        call RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION from its configure.ac.
        When the transition is complete, this autoconf macro can be removed.

2008-05-12      Joel Sherrill <joel.sherrill@OARcorp.com>

        * shared/startup/bspstart.c: Refactored and renamed initialization
        routines to rtems_initialize_data_structures,
        rtems_initialize_before_drivers, rtems_initialize_device_drivers, and
        rtems_initialize_start_multitasking. This opened the sequence up so
        that bootcard() could provide a more robust and flexible framework
        which is easier to explain and understand. This also lays the
        groundwork for sharing the division of available memory between the
        RTEMS workspace and heap and the C library initialization across all
        BSPs.

2008-03-21      Till Straumann <strauman@slac.stanford.edu>

        * shared/console/uart.c: In IRQ driven mode also
        keep reading chars while they are available (fifo
        could be enabled).

2008-03-19      Till Straumann <strauman@slac.stanford.edu>

        * shared/console/console.c, shared/console/uart.c,
        shared/console/uart.h: added support for task-driven
        console.

2008-03-19      Till Straumann <strauman@slac.stanford.edu>

        * shared/startup/pretaskinghook.c: install pointer
        to rtems_malloc_sbrk_helpers_table. This (and derived)
        BSPs rely on sbrk delivering even the first/initial
        chunk of memory.

2008-03-03      Joel Sherrill <joel.sherrill@OARcorp.com>

        * shared/startup/linkcmds: Add wildcard to gcc_except_table section so
        programs compiled with gcc 4.3.x can link.

2008-02-19      Ralf Corsépius <ralf.corsepius@rtems.org>

        * gen405: Remove (Abandoned).
        * helas403: Remove (Abandoned).
        * acinclude: Regenerate.

2007-12-14      Joel Sherrill <joel.sherrill@oarcorp.com>

        * acinclude.m4, gen5200/irq/irq.c, gen5200/startup/bspclean.c: Add
        mvme3100.

2007-12-11      Joel Sherrill <joel.sherrill@OARcorp.com>

        * shared/startup/bspstart.c, shared/startup/pretaskinghook.c: Eliminate
        copies of the Configuration Table. Use the RTEMS provided accessor
        macros to obtain configuration fields.

2007-12-10      Till Straumann <strauman@slac.stanford.edu>

        * Makefile.am, start/preload.S: moved preload.S
        to ../shared/start.

2007-12-10      Till Straumann <strauman@slac.stanford.edu>

        * shared/irq/irq_asm.S, shared/vectors/vectors.h:
        renamed ASM_BOOKE_PIT_VECTOR to ASM_BOOKE_DEC_VECTOR
        to be closer to 'official' nomenclature.

2007-12-10      Till Straumann <strauman@slac.stanford.edu>

        * shared/openpic/openpic.c: fixed wrong register
        address in openpic_gettimer().

2007-12-10      Till Straumann <strauman@slac.stanford.edu>

        * shared/motorola/vpd.c, shared/motorola/vpd.h:
        added code (originally developed for 'beatnik')
        to read MotLoad VPD data from i2c eeprom.

2007-12-10      Till Straumann <strauman@slac.stanford.edu>

        * shared/vectors/README.deprecated, shared/irq/README.deprecated:
        added READMEs stating that certain files should not be
        copy/paste/modified when creating new BSPs. New BSPs
        are encouraged to use the new library under
        libcpu/powerpc/new-exceptions/bspsupport.

2007-12-10      Till Straumann <strauman@slac.stanford.edu>
        
        * shared/vectors/vectors_entry.S, motorola_powerpc/bsp_specs,
        shared/start/vectors_entry.S: moved vectors_entry.S to
        'start' subdir and made a start file rather than
        element of vectors.rel (it should always be linked but
        won't if it is the sole member of vectors.rel).

2007-12-08      Till Straumann <strauman@slac.stanford.edu>

        * shared/vme/vme_universe.c: fixed wrong initialization
        routine when using Tsi148 driver.

2007-12-08      Till Straumann <strauman@slac.stanford.edu>

        * Makefile.am: merged shared/vme/vme_universe.c and
        shared/vme/vme_universe_dma.c into one file.
        Added support for Tsi148 driver (DMA).

2007-12-08      Till Straumann <strauman@slac.stanford.edu>

        * shared/vme/VMEConfig.h, shared/vme/vme_universe.c:
        added support for Tsi148 bridge; BSP can define which
        bridge driver to use from VMEConfig.h.
        Added 'err' macro parameter to BSP_VME_INSTALL_IRQ_MGR(err)
        macro so that an error status can be passed back.

2007-12-08      Till Straumann <strauman@slac.stanford.edu>

        * irq_supp.h: was moved from shared/irq to
        libcpu/powerpc/new-exceptions/bspsupport.

2007-12-08      Till Straumann <strauman@slac.stanford.edu>

        * ep1a/irq/irq.c, gen5200/irq/irq.c, gen83xx/irq/irq_init.c,
        mbx8xx/irq/irq.c, mpc8260ads/irq/irq.c, mvme5500/irq/irq.c,
        psim/irq/no_pic.c, score603e/irq/irq.c, shared/irq/irq_supp.h,
        shared/irq/openpic_i8259_irq.c, virtex/irq/irq_init.c:
        let C_dispatch_irq_handler() return zero to indicate to
        low-level exception handling code that the exception
        was handled (not used yet).

2007-12-08      Till Straumann <strauman@slac.stanford.edu>

        *shared/irq/irq_supp.h: removed cpp test for
        BSP_SHARED_HANDLER_SUPPORT; BSPs using irq_supp.h
        *must* implement shared handlers.

2007-12-06      Till Straumann <strauman@slac.stanford.edu>

        * shared/openpic/openpic.c, shared/openpic/openpic.h:
        added routines to set timer period and interupt mask
        and to read current count.

2007-12-06      Till Straumann <strauman@slac.stanford.edu>

        * virtex/irq/irq_init.c: use new ASM_xxx_VECTOR names.

2007-12-06      Till Straumann <strauman@slac.stanford.edu>

        * shared/vectors/vectors_init.c: replaced 
        switch ( current_ppc_cpu ) { } check by feature check.

2007-12-06      Till Straumann <strauman@slac.stanford.edu>

        * shared/irq/irq_asm.S, shared/vectors/vectors.S:
        Replaced use of hardcoded PPC_EXC_MSR_BITS by a
        run-time method to determine these bits (use settings
        effective before exception occurred).
        Replaced use of hardcoded ASM_VECTORS_CRITICAL by
        'bsp_raw_vector_is_405_critical' variable.

2007-12-05      Till Straumann <strauman@slac.stanford.edu>

        * shared/irq/irq_supp.h: removed stray '*/'. Removed
        inclusion of <stdlib.h> which is unnecessary and broke
        if_dc in an obscure way (due to malloc/free redefinition
        in the networking code).

2007-12-05      Till Straumann <strauman@slac.stanford.edu>

        * shared/irq/irq_asm.S, shared/vectors/vectors.S,
        shared/vectors/vectors.h, shared/vectors/vectors_init.c:
        Converted exception vector names to new ones
        (qualified by <cpu_type> if non-std ppc exceptions).


2007-12-04      Till Straumann <strauman@slac.stanford.edu>

        * shared/startup/bspstart.c: export BSP_commandline_string
        variable.

2007-12-04      Till Straumann <strauman@slac.stanford.edu>

        * shared/flash/flash.c: added lazy init of driver
        from BSP_flashWriteFile().

2007-12-04      Joel Sherrill <joel.sherrill@OARcorp.com>

        * shared/startup/bspstart.c: Move interrupt_stack_size field from CPU
        Table to Configuration Table. Eliminate CPU Table from all ports.
        Delete references to CPU Table in all forms.

2007-12-03      Joel Sherrill <joel.sherrill@oarcorp.com>

        * shared/irq/irq.c: Spacing.

2007-12-03      Joel Sherrill <joel.sherrill@OARcorp.com>

        * shared/startup/bspstart.c: Moved most of the remaining CPU Table
        fields to the Configuration Table. This included pretasking_hook,
        predriver_hook, postdriver_hook, idle_task, do_zero_of_workspace,
        extra_mpci_receive_server_stack, stack_allocate_hook, and
        stack_free_hook. As a side-effect of this effort some multiprocessing
        code was made conditional and some style clean up occurred.

2007-12-03      Joel Sherrill <joel.sherrill@oarcorp.com>

        * shared/irq/irq.c, shared/irq/irq_supp.h: Correct conditionals and
        includes.

2007-12-02      Till Straumann <strauman@slac.stanford.edu>

        * shared/irq/i8259.c, shared/irq/irq.h, shared/irq/irq_supp.h,
        shared/irq/openpic_i8259_irq.c: BSP_disable_irq_at_pic(),
        openpic_disable_irq(), BSP_irq_disable_at_i8259s() now return
        0/1 if irq was disabled/enabled prior to disabling.
        irq_supp.h now exports a inline helper routine for scanning
        a list of shared handlers; to be used by PIC drivers.

2007-12-02      Till Straumann <strauman@slac.stanford.edu>

        * shared/openpic/openpic.c shared/openpic/openpic.h,
        shared/irq/irq_init.c: added more parameters to 
        openpic_init() so that more details of the configuration
        can be overridden/set from the BSP. Moved setup of
        the EPIC-specific EOI delay from BSP code into openpic_init()
        using the new 'epic_freq' parameter.

2007-12-02      Till Straumann <strauman@slac.stanford.edu>
        * shared/openpic/openpic.c, shared/openpic/openpic.h:
        - eliminated conditional compilation (#ifdef mpc8240)
          The difference in register-layout between the EPIC
          and the std. openPIC is handled by an offset parameter
          which can be set at run-time (initialization) with
          a new routine 'openpic_set_src_offset()'.
        - allow BSP to define symbol BSP_OPEN_PIC_BIG_ENDIAN
          which builds the driver for big-endian register access
          (mpc8540).
        - openpic_disable_irq() now returns the old state so
          that it can be restored later.

2007-12-01      Till Straumann <strauman@slac.stanford.edu>

        * shared/irq/openpic_i8259_irq.c:
        - conditionally define 'irq_mask_or_tbl' only if
          BSP_PCI_ISA_BRIDGE_IRQ is defined.
        - use _ISR_Get_level() / _ISR_Set_level() for re-enabling
          interrupts rather than messing with MSR directly;
          these macros:
            o implement compiler memory barrier
                o will handle multiple levels (e500 'critical' interrupts)
                  if they are ever supported.
        - decrementer irqs are also shareable - added list traversal.

2007-12-01      Till Straumann <strauman@slac.stanford.edu>

        * shared/irq/irq_supp.h: Make sure BSP_SHARED_HANDLER_SUPPORT
        is set. The shared irq manager supports shared interrupts
        (but requires also that the PIC-driver supports them by
        traversing the list of shared handlers).
        Declare C_dispatch_irq_handler() which must be defined
        (like the other routines declared in this header) by the
        PIC-driver.

2007-12-01      Till Straumann <strauman@slac.stanford.edu>

        * shared/clock/p_clock.c: (run-time) check for e500-cpu
        and install different ISR for that type of CPU.

2007-12-01      Till Straumann <strauman@slac.stanford.edu>

        * shared/pci/detect_raven_bridge.c: use ifdef mvme2100
        rather than ifdef mpc824x so that we don't depend on
        compile-time CPU flavor. Eventually, this should become
        a run-time check.

2007-12-01      Till Straumann <strauman@slac.stanford.edu>

        * shared/irq/irq.h, shared/irq/irq.c, shared/irq/irq_init.c,
        shared/irq/irq_supp.h (added):
        Removed 'is_processor_irq()' from irq.c; the BSP routines
        BSP_enable_irq_at_pic()/BSP_disable_irq_at_pic() are required
        to ignore processor irqs anyways. Removed
        all BSP-defined constants from irq.c. This makes irq.c (almost)
        binary-compatible among BSPs (ultimate goal is making 'shared'
        a library).
        Added a header (irq_supp.h) defining the interface between
        the generic interrupt manager (irq.c) and the routines it
        requires to be supplied by the BSP (eventually, these
        should go into rtems/irq.h).

        * shared/irq/irq.h, shared/irq/irq_init.c: Removed the definition

        initialize the irqBase member of the rtems_irq_global_settings
        struct. However, irqBase is an rtems_irq_symbolic_name,
        so using BSP_LOWEST_OFFSET is more appropriate.

        for some intel + spansion flash chips (as found on mvme5500,
        mvme6100 and mvme3100 boards).
        A more appopriate place would probably be libchip but
        I don't know if the API is acceptable and if the implementation
        is generic enough (e.g., no CFI support) so I leave it here
        for now.

2007-11-21      Till Straumann <strauman@slac.stanford.edu>

        * shared/console/uart.c: when draining UART during
        initialization (wait for possible printk() activity
        to finish) look at TEMT (fifo, holding-reg and shift-reg)
        rather than THRE (fifo, holding-reg only). This resolved
        some scrambled output issues for me.

        Enhanced semantics: if BSP initializes BSPBaseBaud to a negative
        value then the driver interprets the modulus as a speed value
        and uses the current setting of the divisor to compute the
        clock speed (BSPBaseBaud). This is useful if you have a board
        that you know is initialized e.g., to 9600 but you
        don't know the clock speed.

        This modification is part of the submitted modifications necessary
        to
        support the IBM PPC405 family.  This submission was reviewed by
        Thomas Doerfler <Thomas.Doerfler@imd-systems.de> who ensured it did
        not negatively impact the ppc403 BSPs.  The submission and tracking
        process was captured as PR50.
        * ChangeLog: Removed bogus comment on edit of generated file.
        * acinclude.m4: Added gen405 BSP.

2001-10-25      Joel Sherrill <joel@OARcorp.com>

        * shared/startup/linkcmds: Added _init and _fini.

2001-10-22      Joel Sherrill <joel@OARcorp.com>

        * acinclude.m4: Added mpc8260ads subdirectory.

2001-10-12      Joel Sherrill <joel@OARcorp.com>

        * shared/clock/p_clock.c, shared/startup/bspstart.c: Fixed typo.

2001-10-11      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * .cvsignore: Add autom4te.cache for autoconf > 2.52.
        * configure.ac: New file, generated from configure.in by autoupdate.
        * configure.in: Remove.

2001-10-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * acinclude.m4: New file.
        * configure.in: Use RTEMS_BSP_SUBDIR.

2001-09-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * shared/console/Makefile.am, shared/residual/Makefile.am,
        shared/irq/Makefile.am, shared/motorola/Makefile.am,
        shared/vectors/Makefile.am, shared/pci/Makefile.am,
        shared/openpic/Makefile.am: Use 'PREINSTALL_FILES ='.

2001-05-14      Tom Armistead <tom_armistead@phx.mcd.mot.com>

        * shared/start/start.S: Increased BAT0 mapping of RAM from 64 meg to
        256 meg to allow operation on boards with larger RAM sizes.
        * shared/vectors/vectors_init.c: Modified to call 'generic' powerpc
        vector function (mpc60x_vector_is_valid) instead of MPC750  specific
        function to allow operation on boards with CPUs other than the
        MPC750.

        shared/vectors/vectors.h, shared/vectors/vectors_init.c: Per PR216,
        "libbsp/powerpc/shared" BSP has been modified considerably with the
        goal to make it more flexible and reusable by other BSPs. The main
        strategies were: - eliminate hardcoded base addresses; devices use
        offsets and a BSP defined base address. - separate functionality
        into different files (e.g. reboot from inch.c to reboot.c) which can
        be overridden by a 'derived' BSP. - separate initialization code
        into separate files (e.g.  PCI bridge detection/initialization was
        separated from the more generic PCI access routines), also to make
        it easier for 'derived' BSPs to substitute their own initialization
        code. There are also a couple of enhancements and fixes: - IRQ
        handling code now has a hook for attaching a VME bridge. - OpenPIC
        is now explicitely initialized (polarities, senses). Eliminated the
        implicit assumption on the presence of an ISA PIC. - UART and
        console driver now supports more than 1 port. The current maximum of
        2 can easily be extended by enlarging a table (it would even be
        easier if the ISR API was not broken by design). - fixed polled_io.c
        so it correctly supports console on COM2 - fixed TLB invalidation
        code (start.S). - exception handler prints a stack backtrace. -
        added BSP_pciFindDevice() to scan the pci bus for a particular
        vendor/device/instance.

        * shared/startup/linkcmds: In support of gcc 3.1, added one of more
        of the sections .jcr, .rodata*, .data.*, .gnu.linkonce.s2.*,
        .gnu.linkonce.sb2.*, and .gnu.linkonce.s.*.  Spacing corrections and
        direction of segments to memory regions may also have been
        addressed.  This was a sweep across all BSPs.

2001-04-08      Joel Sherrill <joel@OARcorp.com>

        * shared/startup/linkcmds: Per PR170, PR171, and PR172 add .eh_frame

2001-03-30      Eric Valette <valette@crf.canon.fr>

        * shared/Makefile.am, shared/console/consoleIo.h,
        shared/include/bsp.h: These modifications are part of the conversion
        of the mpc8xx CPU to the "new exception processing model."
        * configure.in, motorola_powerpc/Makefile.am,
        motorola_powerpc/configure.in: These modifications are in support of
        switching the mpc8xx to the use the "new exception processing
        model."

2000-11-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.

2000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I
        $(RTEMS_TOPdir)/aclocal.

2000-11-01      Joel Sherrill <joel@OARcorp.com>

        * shared/startup/bspstart.c: assoc.h, error.h, libio_.h, libio.h,
        and libcsupport.h moved from libc to lib/include/rtems and now must
        be referenced as <rtems/XXX.h>.   Header file order was cleaned up
        while doing this.

2000-10-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros. Switch to
        GNU canonicalization.

2000-09-29      Charles-Antoine Gauthier <charles.gauthier@nrc.ca>

        * shared/startup/linkcmds: Added lines so DWARF debug information
        would be available.  Otherwise gdb complains that the offsets for
        the debug info are incorrect and doesn't load the files.

2000-09-05      Joel Sherrill <joel@OARcorp.com>

        * shared/start/start.S: Include proper files to compile.

2000-08-10      Joel Sherrill <joel@OARcorp.com>

        * ChangeLog, shared/ChangeLog: New file.
