2001-11-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * configure.ac: Remove old_exception_processing,
        new_exception_processing.
        * Makefile.am: Ditto.

2001-11-21      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

2001-11-14      Till Straumann <strauman@SLAC.Stanford.EDU>

        * new_exception_processing/cpu_asm.S: Support double or single
        precision context switches.  Note that doing a single precision
        context save/restore on a double precision PowerPC machine does not
        only result in rounding errors but also screws up the FPSCR register!

2001-11-08      Dennis Ehlin (ECS) <Dennis.Ehlin@ecs.ericsson.se>

        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.
        * ppc403/console/console405.c ppc403/tty_drv/.cvsignore,

        ppc403/timer/timer.c: Modified.

2001-11-07      Joel Sherrill <joel@OARcorp.com>

        * configure.ac: Delete the commented out line that said that
        the mpc8260 used the old exception processing model.  This line
        also appears to have caused ppc603e to miss this test.

2001-10-29      Joel Sherrill <joel@OARcorp.com>

        * mpc8xx/timer/timer.c: Added hack for two macros that are not defined
        with the new exception processing model:
                rtems_cpu_configuration_get_timer_least_valid()
                rtems_cpu_configuration_get_timer_average_overhead()
        This is captured as PR57.

        * shared/include/cpu.h: Renamed delay() to rtems_bsp_delay().

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

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.

2001-05-24      Tom Armistead <tom_armistead@phx.mcd.mot.com>

        * mpc6xx/timer/timer.c: Added include of bsp.h and removed
        external declaration of BSP_Convert_decrementer() to 
        correct unresolved reference to this routine.

2001-05-24      Eric Valette <valette@crf.canon.fr>

        * mpc8xx/console-generic/console-generic.c: Bug found by Yacine
        <elkolli@crf.canon.fr> where the initialization or irq data structure
        was incomplete in case a SMC channel was used first and later a SCC one.

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

        * mpc8xx/vectors/.cvsignore, mpc8xx/vectors/Makefile.am,
        mpc8xx/vectors/README, mpc8xx/vectors/align_h.S
        mpc8xx/vectors/vectors.S:  These files were removed in
        support of switching the mpc8xx to the use the "new exception
        processing model."

        new_exception_processing/cpu.h, shared/include/byteorder.h,
        wrapup/Makefile.am:  This is conversion of the
        mpc8xx CPU to the "new exception processing model."

2001-02-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * mpc505/ictrl/Makefile.am, mpc6xx/clock/Makefile.am,
        mpc6xx/exceptions/Makefile.am, mpc6xx/mmu/Makefile.am,
        mpc8xx/include/Makefile.am, new_exception_processing/Makefile.am,
        old_exception_processing/Makefile.am, pc403/ictrl/Makefile.am,
        shared/include/Makefile.am, shared/src/Makefile.am:
        Apply *_HEADERS instead of *H_FILES.
        * shared/src/.cvsignore: Add cache.h.

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

        * 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.

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.

2000-10-26      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

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

2000-10-20      Joel Sherrill <joel@OARcorp.com>

        * 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.

2000-10-20      Joel Sherrill <joel@OARcorp.com>

        * 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.
        * mpc505/ictrl: New directory.
        * configure.in, mpc505/Makefile.am: Modified to reflect ictrl addition.
        * mpc505/ictrl/.cvsignore, mpc505/ictrl/Makefile.am,
        mpc505/ictrl/ictrl.c, mpc505/ictrl/ictrl.h: New files.
        * mpc505/timer/timer.c: Use <rtems.h>, not "rtems.h".
        * mpc505/vectors/Makefile.am: alignment exception handler now included.
        * mpc505/vectors/vectors.S: Now use constants for exception numbers.
        * old_exception_processing/ppc_offs.h: New file.
        * old_exception_processing/Makefile.am: Account for ppc_offs.h.
        * old_exception_processing/cpu.h: Make Nest and Disable levels volatile.
        * old_exception_processing/cpu_asm.S: Offsets moved to ppc_offs.h.

2000-10-18      Joel Sherrill <joel@OARcorp.com>

        * 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.

2000-10-18      Joel Sherrill <joel@OARcorp.com>

        * mpc8xx/console-generic/console-generic.c: Removed warnings.

        * mpc6xx/clock/c_clock.c, mpc6xx/clock/c_clock.h: Removed use of
        bsp.h and replaced it with use of proper interfaces or explicit
        externs of required functions and data.
        * mpc6xx/timer/timer.c: Ditto.

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