        * shared/irq/irq_asm.S: Currently, all (new exception) BSPs
        explicitely enable the FPU across the user ISR but DONT save/restore
        the FPU context. Any use of the FPU fron the user handler (e.g., due
        to GCC optimizations) result in corruption. The fix results in an
        exception in such cases (user ISR must explicitely
        save/enable/restore FPU).

        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.

        * 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.

2001-05-14      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.

2001-05-09      Joel Sherrill <joel@OARcorp.com>

        * 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.
