        * cpu_asm.S: When the type rtems_boolean was switched to the C99 bool,
        the size changed from 4 bytes to 1 byte. The interrupt dispatching
        code accesses two boolean variables for scheduling purposes and the
        assembly implementations of this code did not get updated.

        * rtems/score/cpu.h: Change prototype of IDLE thread to consistently
        return void * and take a uintptr_t argument.

        comments.

2008-12-17      Ralf Corsépius <ralf.corsepius@rtems.org>

        * rtems/m68k/m68360.h: added port b pin definitions for SPI

2008-06-13      Joel Sherrill <joel.sherrill@oarcorp.com>

        * rtems/score/m68k.h: There is no point in defining the maximum
        priorities to 255. priority.h will default it to this.

2008-06-10      Chris Johns <chrisj@rtems.org>

        * cpu_asm.S: Add Coldfire FPU support.
        * rtems/score/m68k.h: Change the Coldfire CPU defines to be based

2008-06-05      Joel Sherrill <joel.sherrill@OARcorp.com>

        * rtems/score/cpu.h: Add CPU_SIMPLE_VECTORED_INTERRUPTS porting
        parameter to indicate that the port uses the Simple Vectored
        Interrupt model or the Programmable Interrupt Controller Model. The
        PIC model is implemented primarily in the BSP and it is responsible
        for all memory allocation.

        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>

        * rtems/score/cpu.h: 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.

2007-11-26      Joel Sherrill <joel.sherrill@oarcorp.com>

        * rtems/score/cpu.h: Eliminate the interrupt_vector_table field in the
        m68k CPU Table since it is never read.

        bits are used when calculating the exception vector.

        interrupt enable/disable/flash operations.  The "memory" barrier will
        move the the generic interrupt enable/disable/flash macros.

        * rtems/score/m68k.h: Add "memory" to the clobbered register list for

        the compiler from hoisting/sinking other operations past the interrupt
        enable/disable/flash operations.

        * cpu_asm.S: Per PR267, the _ISR_Handler() function never was modifying
        _ISR_Nest_level, and _Watchdog_Insert() requires this variable
        to be modified to determine if an interrupt may have modified
        the watchdog chain.  Prior to modifying _ISR_Handler(), I had
        a test that would fail if _ISR_Flash was not commented out in
        _Watchdog_Insert().  After this modification was made, my test
        ran flawlessly.

        * rtems/score/Makefile.am: Use 'PREINSTALL_FILES ='.
        * Makefile.am: Use 'PREINSTALL_FILES ='.

2001-08-09      Chris Johns <ccj@acm.org>

        * cpu_asm.S: This patch was co-developed with Eric Norum
        <eric.norum@usask.ca>.  It closes a one instruction window
        on some m68k CPU cores.  It fixes symptoms seen as:
            1) No more `interrupt handler invoked twice for
               a single interrupt'.
            2) No more `lockup when mc68360 CPM and PIT interrupts
               are at different levels'.
        It does insert a little more overhead on machines without hardware
        interrupt stacks but correctness has a price.

2001-02-04      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * Makefile.am, rtems/score/Makefile.am: 
        Apply include_*HEADERS instead of H_FILES.

2001-01-03      Joel Sherrill <joel@OARcorp.com>

        * rtems/score/cpu.h: Added _CPU_Initialize_vectors().
        * cpu_asm.S: Modify to properly dereference _ISR_Vector_table
        now that it is dynamically allocated.

2000-12-19      Joel Sherrill <joel@OARcorp.com>

        * cpu.c: Do not read or write raw interrupt vector table if
        we are on a CPU that does not have a %vbr register and the
        BSP is configured as having the table in ROM.

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.

2000-10-25      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

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

2000-10-19  Antti P Miettinen  <anmietti@trshp.ntc.nokia.com>

        * rtems/score/cpu.h: define CPU_Exception_frame for rdbg.
        * m68302.h: Make buffer pointer in m302_SCC_bd volatile.

        * sim.h: These changes enable RTEMS to automatically generate
        the ram_init file used by gdb with the BDM patches. The 332 has
        on-board chip select lines (for RAM and FLASH) that must be
        configured before use of these peripherals. These patches parse
        data from start.c where the chip select lines are configured in
        the runtime executable and automatically generates the gdb
        initialization file using the same settings. A great time saver.
        A similar file, ram_init_FW (flash writable), is also generated
        that the flash programming tool uses.
        * BSP/start/start.c: Must be modified to support above.
        * BSP/start/ram_init.ld, BSP/start/ram_init.sed: New files.

2000-09-04      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * Makefile.am: Include compile.am.

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

        * ChangeLog: New file.
