        PR 1385/cpukit
        * mpc5xx/irq/irq_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.

2009-02-13      Joel Sherrill <joel.sherrill@OARcorp.com>

        * new-exceptions/cpu.c: Correct prototype of _CPU_Initialize.

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

        * shared/include/powerpc-utility.h: Use constraint "b" for address
        base registers in inline assembler statements.

        * mpc55xx/dspi/dspi.c, mpc55xx/edma/edma.c, mpc55xx/esci/esci.c,

        changes.

2008-10-01      Ralf Corsépius <ralf.corsepius@rtems.org>

        * mpc83xx/include/mpc83xx.h: #include <bspopts.h> to make sure 
        defines from bspopts.h get propagated.

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

        * mpc8xx/mpc8xx.h, mpc8xx/timer/timer.c: minor additions

        * mpc83xx/i2c/mpc83xx_i2cdrv.c: wait, 'til STOP has been executed

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

        * mpc8xx/clock/clock.c: adapt PIT driver to more complex PLL in
        MPC866 and firends

        * mpc8xx/cpm/cp.c: use correct type for interrupt level

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

        mpc8xx/clock/clock.c, ppc403/clock/clock.c, ppc403/clock/clock_4xx.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      Joel Sherrill <joel.sherrill@oarcorp.com>

        * mpc6xx/clock/c_clock.c: CLOCK_DRIVER_USE_FAST_IDLE must be checked to

2008-07-27      Ralf Corsépius <ralf.corsepius@rtems.org>

        * Makefile.am: Remove doxygen comments.

2008-07-22      Till Straumann <strauman@slac.stanford.edu>

        * ppc403/clock/clock.c: Added (conditionally compiled)
        code so that a BSP can choose to hook the timer exception
        directly rather than going through the interrupt dispatcher.

2008-07-21      Till Straumann <strauman@slac.stanford.edu>

        * new-exceptions/raw_exception,h,
        new-exceptions/raw_exception.c: Added more vectors for PPC405:
        watchdog, fpu-unavail, apu-unavail, itlbmiss, dtlbmiss, debug.
        
2008-07-18      Sebastian Huber <sebastian.huber@embedded-brains.de>

        * shared/include/powerpc-utility.h: Changed special purpose register
        inline functions to macros.  Added macros to set and clear bits for
        SPRs and DCRs.

        * new-exceptions/raw_exception.c: The watchdog exception for e200 is
        now asynchronous.

        * mpc83xx/gtm/gtm.c: Bugfix for some value assignments.

        * mpc55xx/include/watchdog.h: New file.

        * Makefile.am: Install mpc55xx/include/watchdog.h for MPC55XX.

2008-07-18      Thomas Doerfler <thomas.doerfler@embedded-brains.de>

        * mpc83xx/network/tsec.c: Initialize PHY registers late enough,
        so that phy access is possible

2008-07-17      Thomas Doerfler <thomas.doerfler@embedded-brains.de>

        * rtems/powerpc/powerpc.h:
        ppc405 uses definitions distinct from ppc403 now
        * shared/src/cache_.h: Use correct powerpc.h to get cache attributes

        
2008-07-17      Thomas Doerfler <thomas.doerfler@embedded-brains.de>

        * shared/include/powerpc-utility.h:
        Fixed typo in access macros for device control registers (DCR)
        
2008-07-16      Till Straumann <strauman@slac.stanford.edu>

        * new-exceptions/bspsupport/vectors_init.c: added
        features to C_exception_handler() (the default global
        handler):
         - try to catch recursion
         - print info about context where the exception occurred
           (ISR or task with task ID).
         - suspend offending task rather than spinning forever.
        
2008-07-16      Till Straumann <strauman@slac.stanford.edu>

        * new-exceptions/bspsupport/vectors_init.c: must not
        align start of stack downwards (we don't 'own' memory
        below start). Instead, use original boundaries but
        align the stack pointer as required.

        Added test to verify that R13 was loaded with _SDA_BASE_
        during early initialization (low-level assembly code
        relies on it).

2008-07-16      Till Straumann <strauman@slac.stanford.edu>

        * new-exceptions/cpu.c: propagate R2 to all task contexts
        even if the ABI is SVR4. Cannot hurt...

2008-07-16      Till Straumann <strauman@slac.stanford.edu>

        * new-exceptions/cpu.c: use ppc_interrupt_get_disable_mask()
        to determine which bits to set/clear from _CPU_Context_Initialize().

2008-07-16      Till Straumann <strauman@slac.stanford.edu>

        * new-exceptions/bspsupport/ppc_exc_asm_macros.h: Added
        a test to TEST_LOCK_crit so that a context switch is
        always prevented if MSR_CE is not set in the interrupt mask.
        (Support mode where the user wants to leave MSR_CE always enabled
        but abstains from calling OS primitives from the exception
        handler.)

2008-07-16      Till Straumann <strauman@slac.stanford.edu>

        * shared/include/powerpc-utility.h: Added 
        GET_INTERRUPT_MASK macro.

2008-07-16      Joel Sherrill <joel.sherrill@oarcorp.com>

        * mpc6xx/clock/c_clock.c: Add fast idle.

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

        * configure.ac: Support for MPC55XX.  Changed comment format to
        Doxygen.

        mpc55xx/misc/flash.S, mpc55xx/misc/fmpll.S: New BSP.

        * mpc83xx/i2c/mpc83xx_i2cdrv.c,
        mpc83xx/network/tsec.c, mpc83xx/spi/mpc83xx_spidrv.c,
        mpc83xx/spi/mpc83xx_spidrv.h: Support for MPC8313ERDB.

        * shared/include/powerpc-utility.h: Exchanged ASM and non ASM code
        sections.

        * rtems/powerpc/powerpc.h, shared/src/cache.c, shared/src/cache_.h:
        New defines PPC_NO_CACHE_ALIGNMENT and PPC_NO_CACHE_ALIGNMENT_POWER for
        CPUs with no cache.  Provide default implementations for all cache
        functions.

        * mpc83xx/include/gtm.h, mpc83xx/gtm/gtm.c: New files.

2008-07-14      Thomas Doerfler <thomas.doerfler@embedded-brains.de>

        * shared/include/cpuIdent.c, shared/include/cpuIdent.h,
        * shared/include/powerpc-utility.h:
        Added support for PPC405EX (contributed by Michael Hamel)
        
2008-07-11      Sebastian Huber <sebastian.huber@embedded-brains.de>

        * Makefile.am: Install powerpc-utility.h.

        * shared/include/cpuIdent.h, shared/include/cpuIdent.c: Added e200 and
        e300 features.

        * new-exceptions/cpu.c: Removed PR288 bugfix check.

        * new-exceptions/e500_raw_exc_init.c: Added initialization for e200.
        Set IVPR register for e200 and e500 to ppc_exc_vector_base.

        * new-exceptions/raw_exception.c, new-exceptions/raw_exception.h: Added
        vector categories for e200 and e300 cores.  Added global variable
        ppc_exc_vector_base for CPUs with IVPR register.

        * new-exceptions/bspsupport/ppc_exc.S,
        * new-exceptions/bspsupport/ppc_exc_asm_macros.h,
        * new-exceptions/bspsupport/ppc_exc_bspsupp.h,
        * new-exceptions/bspsupport/ppc_exc_hdl.c,
        * new-exceptions/bspsupport/vectors.h,
        * new-exceptions/bspsupport/vectors_init.c: 
        Conistent code layout in most assember code sections and usage of
        defines for registers.  Usage of standard header files to avoid
        multiple definitions. 
        
        Optimized exception code: Removed many branches and exploit branch
        prediction for asynchronous exceptions, moved common wrap code into
        WRAP macro to eliminate branch, static initialization of the handler
        table with a default handler to eliminate the test if a handler is
        present.  Register CR6 is no more cleared because the exeption handler
        functions are not variadic.
        
        New method to switch to the interrupt stack. It will be tested if the
        exception stack pointer is already inside the interrupt stack area.  It
        is no more necessary to disable interrupts.  The SPRG1 and SPRG2 are
        used to store the initial interrupt stack pointer and the interrupt
        stack memory area start.

        Removed variable ppc_exc_msr_irq_mask and use general interrupt disable
        mask from SPRG0 instead.

        New initialization routine ppc_exc_initialize() for bsp_start().  It
        takes the interrupt disable mask, interrupt stack start and size as
        parameters.

        Added packed prologues for CPUs with IVPR and IVOR registers to save
        memory space.

        Reverted ppc_exc_crit_always_enabled change from yesterday.

        WARNING: Tests with critical interrupt exceptions crash the system at
        least on MPC8313ERDB and MPC8349EAMDS.  There may be somewhere a
        serious bug with the new code.

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

        * mpc6xx/mmu/pte121.c: use general "memory" clobber
        rather than memory input operand in inline assembly
        ("m" doesn't do what the manual says; see discussion
        on gcc mailing list around 2008/3/30)

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

        * ChangeLog, mpc8xx/clock/clock.c, ppc403/clock/clock.c,
        ppc403/irq/ictrl.h, rtems/powerpc/powerpc.h:
        Removed all macro definitions which depended on
        the compiler defining a PPC CPU-model dependent
        symbol from files in cpukit.
        Macros which were not used by cpukit have been
        moved to libcpu/powerpc/rtems/powerpc/powerpc.h.

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

        * new-exceptions/bspsupport/README,
        new-exceptions/bspsupport/ppc_exc.S,
        new-exceptions/bspsupport/ppc_exc_asm_macros.h,
        new-exceptions/bspsupport/ppc_exc_bspsupp.h,
        new-exceptions/bspsupport/ppc_exc_hdl.c,
        new-exceptions/bspsupport/vectors_init.c:
        Fixed and enabled stack-switching algorithm which figures out
        if we already run on the ISR stack rather than relying on the
        _ISR_Nest_level.
        Added 'ppc_exc_crit_always_enabled' variable which defines
        the semantics of critical interrupts.
        Let asynchronous machine-check handling never call the dispatcher.
        We don't want to disable MSR_ME ever (to avoid checkstops)
        and hence asynchronous MEs must not use OS services anyways.

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

        * shared/include/powerpc-utility.h: Includes standard header files,
        provides common assembler macros and inline functions for low-level
        code.

2008-05-23      Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>

        * mpc83xx/network/tsec.c:
        disabled debugging output, reduced rx interrupt coalescing

        * ppc403/tty_drv/tty_drv.c, ppc403/console/console405.c:
        ../ictrl/ictrl.h has gone; include ../irq/ictrl.h

2008-05-16      Joel Sherrill <joel.sherrill@OARcorp.com>

        * mpc83xx/include/mpc83xx.h: or is not a good name for any name in
        C/C++. See iso646.h for the reason.

2008-05-15      Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>

        * mpc83xx/i2c/mpc83xx_i2cdrv.c:
        disabled debugging output

2008-05-15      Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>

        * mpc83xx/network/tsec.c, mpc83xx/include/mpc83xx.h:
        added support for RGMII interface and different board

2008-05-15      Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>

        * mpc83xx/i2c/mpc83xx_i2cdrv.c, mpc83xx/i2c/mpc83xx_i2cdrv.h,

        added base frequency into softc structure

2008-05-14      Till Straumann <strauman@slac.stanford.edu>

        * new-exceptions/bspsupport/ppc_exc_bspsupp.h: added
        comment about the semantics of the return value of 
        ppc_exc_handler_t.

2008-05-14      Till Straumann <strauman@slac.stanford.edu>

        * new-exceptions/bspsupport/irq.c: moved malloc/free
        outside of irq-protected critical section.

2008-04-24      Joel Sherrill <joel.sherrill@OARcorp.com>

        * mpc8260/console-generic/console-generic.c,
        mpc8xx/console-generic/console-generic.c: Remove all references to
        console_reserve_resources and termios_reserve_resources.

2008-04-24      Nigel Spon <nigel@adi.co.nz>

        * ppc403/console/console.c: Correct include path.

2008-04-23      Joel Sherrill <joel.sherrill@OARcorp.com>

        Remove all references to console_reserve_resources and
        termios_reserve_resources.

2008-04-07      Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>

        * README: 
        removed reference to outdated "old-exception-handling" PPC support

2008-03-20      Till Straumann <strauman@slac.stanford.edu>

        * new-exceptions/bspsupport/irq.c: don't disable irqs
        at the interrupt controller (PIC) during initialization -- this
        caused problems where some BSPs's BSP_disable_irq_at_pic() routine
        did not ignore IRQ lines associated with cascaded PICs.
        Rely on the BSP (BSP_setup_the_pic()) to provide a good
        initial setup.

2008-03-13      Till Straumann <strauman@slac.stanford.edu>

        new-exceptions/bspsupport/README,
        new-exceptions/bspsupport/ppc_exc_hdl.c:
        Thomas Doerfler clarified (thanks!) that raising an
        exception and executing the 1st instruction is not
        an atomical operation. I added a fix to the code that
        checks if a lower-priority interrupt is under way:
        we now not only test if the 'lock' variable was set
        but also check if the interrupted PC points to the
        'write lock' instruction.
        Added more comments and updated README.

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

        * new-exceptions/raw_exception.c, new-exceptions/raw_exception.h:
        Removed all #ifdef <cpu_flavor>. All exception vectors are now
        always defined.
        Changed implementation of <cpu>_vector_is_valid() from 'case'
        statements to table lookup.
        Replaced 'ASM_VECTORS_CRITICAL' by a variable
        'bsp_raw_vector_is_405_critical' which is set at run-time.
        Removed PPC_MSR_EXC_BITS. The exception handling code
        (libbsp/shared/vectors/vectors.S and ../irq/irq_asm.S) now
        has a run-time check for these bits.
        Both files are now free of #if <cpu_flavor> constructs.

        point for cleanup (remove as many branches as possible;
        replace by run-time tests if necessary).

2007-12-05      Joel Sherrill <joel.sherrill@OARcorp.com>

        * new-exceptions/raw_exception.c: Conditionalize call to

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

        * new-exceptions/raw_exception.c, new-exceptions/raw_exception.h:
        Added typedef for exception classes (classic, critical, ...
        synchronous / asynchronous). ppc_vector_is_valid() now returns
        the appropriate class.

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

        * new-exceptions/raw_exception.c: made all <cpu>_vector_is_valid()
        subroutines that are called from ppc_vector_is_valid() 'static'.

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

        * new-exceptions/raw_exception.c, new-exceptions/raw_exception.h:
        Qualified all exception vector symbols that are only defined
        #ifdef <cpu_flavor> with <cpu_flavor> in the symbol name.
        If the special flavor __ppc_generic is effective the ALL
        vector symbols are available and ppc_vector_is_valid() works
        for all supported CPUs (run-time check).
        This is work towards a #ifdef <cpu_flavor> free libcpu and
        exception framework.

        * mpc5xx/console-generic/console-generic.c, mpc8260/timer/timer.c,
        new-exceptions/cpu.c, old-exceptions/cpu.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.

2007-12-04      Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>

        * mpc83xx/spi/mpc83xx_spidrv.c, mpc83xx/spi/mpc83xx_spidrv.h:

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

        * mpc5xx/console-generic/console-generic.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.

        This is probably only used by the simulator (were else
        can you install something to ROM ??).

2007-11-29      Till Straumann <strauman@slac.stanford.edu>

        * shared/include/cpuIdent.h, shared/include/cpuIdent.c:
        Added a simple 'feature check' facility. Code should
        not check for a particular CPU type if possible but
        check the respective feature bit (e.g., 'has_altivec').
        This makes it much less cumbersome to add more CPU
        types in the future.

2007-11-29      Till Straumann <strauman@slac.stanford.edu>

        * rtems/powerpc/registers.h, rtems/score/ppc.h: Per PR213, add  the
        following: - support for the MPC74000 (AKA G4); there is no AltiVec
        support yet, however. - the cache flushing assembly code uses
        hardware-flush on the G4. Also, a couple of hardcoded numerical
        values were replaced by more readable symbolic constants. - extended
        interrupt-disabled code section so enclose the entire cache
        flush/invalidate procedure (as recommended by the book). This is not
        (latency) critical as it is only used by init code but prevents
        possible corruption. - Trivial page table support as been added.
        (1:1 effective-virtual-physical address mapping which is only useful
        only on CPUs which feature hardware TLB replacement, e.g. >604. 
        This allows for write-protecting memory regions, e.g. text/ro-data
        which makes catching corruptors a lot easier. It also frees one
        DBAT/IBAT and gives more flexibility for setting up address maps :
        -) - setdbat() allows changing BAT0 also (since the BSP may use a
        page table, BAT0 could be available...). - asm_setdbatX() violated
        the SVR ABI by using r20 as a scratch register; changed for r0 -
        according to the book, a context synchronizing instruction is
        necessary prior to and after changing a DBAT -> isync added
        * new-exceptions/cpu.c: Per PR211 fix saving/restoring floating
        point context.  The fpsave and fprestore routines are only used in a
        executing context which _is_ fp and hence has the FPU enabled. The
        current behavior required the FPU always to be on which is very
        dangerous if lazy context switching is used.   [Joel Note: Some
        ports explicitly enabled the FPU in the FP save and restore routines
        to avoid this.] The patch also makes sure (on powerpc only) that the
        FPU is disabled for integer tasks. Note that this is crucial if
        deferred fp context switching is used. Otherwise, fp context
        corruption may go undetected! Also note that even tasks which merely
        push/pop FP registers to/from the stack without modifying them still
        MUST be FP tasks - otherwise (if lazy FP context switching is used),
        FP register corruption (of other, FP, tasks may occur)! Furthermore,
        (on PPC) by default, lazy FP context save/restore is _disabled_.
        * shared/include/io.h: Per PR215 address the following issues: -
        _IO_BASE, _ISA_MEM_BASE and PCI_DRAM_OFFSET are no longer defined by
        libcpu (powerpc/shared/include/io.h) but by the BSP (who is the only
        one to know the values) - the affected BSP (shared/motorola) headers
        have been fixed in a separate "libbsp/powerpc/shared" patch. - the
        DEC 21140 driver (libchip/network/dec21140.c) has been fixed to use
        PCI_DRAM_OFFSET instead of PREP_PCI_DRAM_OFFSET. and PCI_MEM_BASE
        instead of PREP_ISA_MEM_BASE. PCI_MEM_BASE is to be defined by the
        BSP who is using this driver. - the DEC driver also has been fixed
        to use the newer rtems_bsp_delay_in_bus_cycles() instead of the
        obsolete delay_in_bus_cycles().

        * shared/include/cpu.h: Added ifndef ASM.

2001-04-03      Joel Sherrill <joel@OARcorp.com>

        * Closed PR57.  The hack is OK as it allows a BSP to override or not
        at its discretion.
        * Per PR94, all rtems/score/CPUtypes.h are named
        rtems/score/types.h.

        * new_exception_processing/cpu.h, old_exception_processing/cpu.c:
        old_exception_processing/cpu.h, Added _CPU_Initialize_vectors(). In
        particular, spurious vector initialization had to be moved on old
        exception processing model.

        * mpc8xx/console-generic/console-generic.c: Avoid use of BSP
        definitions and rely on the new routine
        mbx8xx_console_get_configuration() to get information.  This routine
        was formerly incorrectly called
        mbx8xx_console_use_maximum_buffer_size(). binding to the exception
        code.
        * configure.in, Makefile.am: Explicitly specify whether an
        RTEMS_CPU_MODEL is using old or new exception processing.  This is
        important because when building multilib, you do not know  the
        RTEMS_CPU_MODEL.  So everything built in a multilib'ed RTEMS must be
        independent of the exception model and allow for late binding to the
        exception code.

2000-10-18      Sergei Organov <osv@javad.ru>

        * Added full support for MPC505.

        * mpc8xx/console-generic/console-generic.c: Removed include of
        <bsp.h> by adding BSP dependent routine
        mbx8xx_console_use_maximum_buffer_size() which can be hard coded or
        check non-volatile memory for configuration.
        * mpc8xx/console-generic/console-generic.c: Removed warnings.

2000-06-08      Eric Valette <valette@crf.canon.fr>

        * mpc8xx/console-generic/console-generic.c: The printk/printf did
        not work when loaded by EPPCBUG. They did work when loaded with the
        BDM debugger.  I suspected EPPBUG  made some nasty things like
        patching Communication processor microcode...  Anyway, the attached
        patch: 1) Enables to have printk nearly immediately after boot, 2)
        Make printf work automagically (I do not know why except I make a 
        different initialization for printk that should be overwritten by 
        console init later ?) I let the default to be using EPPCBUG embedded
        firmware to boot and  using this printk early enabler code
        (LOADED_BY_EPPCBUG and  EARLY_CONSOLE) are on.
