138
139        * shared/irq/openpic_i8259_irq.c: fixed type of
140        'frame' argument to C_dispatch_irq_handler(). It's

142
1432006-07-12      Till Straumann <strauman@slac.stanford.edu>
144
145        * shared/startup/probeMemEnd.c: added paranoia to inline

161
162        * shared/vme/vme_universe.c: Only set/access the
163        _BSP_vme_bridge_irq variable on BSPs that

172
173        * shared/startup/bspstart.c: fixed compiler warnings
174        (bspIo.h inclusion, cast of number constants to pointers).
175        Enable L1 cache on mvme2100.
176
1772006-06-19      Till Straumann <strauman@slac.stanford.edu>
178
179        * shared/irq/irq_asm.S: Never allow the FPU to be switched on
180        for integer-only tasks (new gcc may use FP regs implicitly).
181
1822006-03-08      Joel Sherrill <joel@OARcorp.com>
183
184        * shared/startup/linkcmds: Add .gnu.linkonce.b.* section.
185
1862006-02-13      Till Straumann <strauman@slac.stanford.edu>
187
188        * shared/startup/panic.c, shared/startup/probeMemEnd.c:
189        added code for BSPs to use: panic using printk() to display
190        reason. probeMemEnd() to determine memory size by probing.
191
1922006-02-08      Joel Sherrill <joel@OARcorp.com>

201
202        * shared/vectors/vectors.S: mask high bits when calculating
203        the exception vector number to yield correct result even if
204        the vectors reside in the upper area (0xfff00000; psim).
205
2062005-12-02      Till Straumann <strauman@slac.stanford.edu>
207
208        * shared/irq/irq_init.c, shared/openpic/openpic.h
209        shared/openpic/openpic.c: The 8240's EPIC has a 'serial'
210        mode of operation for multiplexing 16 interrupt lines.
211        This introduces a pipeline delay which can cause
212        spurious interrupts unless ending the interrupt cycle
213        (EOI) is delayed accordingly.
214
2152005-12-01      Till Straumann <strauman@slac.stanford.edu>
216
217        * shared/vectors/vectors.h, shared/vectors/vectors.S,

219        prologue (some exceptions, e.g., altivec unavail.) are only
220        0x20 bytes apart. Also introduced a modified prologue
221        that switches r0..r3 shadowing off (r0..r3 undefined
222        on certain 603e variants when incurring a TLB miss).
223
2242005-11-29      Till Straumann <strauman@slac.stanford.edu>
225
226        * shared/irq/irq_asm.S, shared/vectors/vectors.S: Clear
227        CR[6] before invoking high-level handler to make sure no
228        varargs fn callee assumes there are FP arguments.
229
2302005-11-29      Till Straumann <strauman@slac.stanford.edu>
231
232        * shared/irq/irq.c: Fixed incorrect removal of first shared

242        mvme5500/start/preload.S, mvme5500/startup/bspstart.c,
243        shared/startup/bspstart.c: moved linkcmds to shared area for other
244        BSPs to use
245

249        shared/residual/residual.c: silenced compiler warnings (type cast &
250        renaming puts->my_puts)
251
2522005-11-02      Till Straumann <strauman@slac.stanford.edu>
253
254        * mvme5500/start/start.S, shared/start/start.S,
255        shared/startup/bspstart.c: moved assembly code to C; setdbat now
256        supports high bats on 7450 CPUs; added argument checking to setdbat;
257        added getdbat; moved early initialization code (clear_bats) from BSP
258        to libcpu (CPU_clear_bats_early)
259
2602005-10-20      Eric Norum <norume@aps.anl.gov>
261
262        * shared/pci/detect_raven_bridge.c, shared/startup/bspstart.c

2652005-10-17      Ralf Corsepius <ralf.corsepius@rtems.org>
266
267        * Makefile.am: Merge-in shared/Makefile.am.
268        * configure.ac: Remove shared/Makefile.am.
269        * ChangeLog: Merge-in shared/ChangeLog.
270
2712005-10-06      Till Straumann <strauman@slac.stanford.edu>
272
273        PR 833/bsps
274        * shared/irq/irq_asm.S: Currently, all (new exception) BSPs
275        explicitely enable the FPU across the user ISR but DONT save/restore
276        the FPU context. Any use of the FPU fron the user handler (e.g., due
277        to GCC optimizations) result in corruption. The fix results in an
278        exception in such cases (user ISR must explicitely
279        save/enable/restore FPU).

772
773        * acinclude.m4: New file.
774        * configure.in: Use RTEMS_BSP_SUBDIR.
775
7762001-09-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
777
778        * shared/console/Makefile.am, shared/residual/Makefile.am,
779        shared/irq/Makefile.am, shared/motorola/Makefile.am,
780        shared/vectors/Makefile.am, shared/pci/Makefile.am,
781        shared/openpic/Makefile.am: Use 'PREINSTALL_FILES ='.

7832001-05-14      Tom Armistead <tom_armistead@phx.mcd.mot.com>
784
785        * shared/start/start.S: Increased BAT0 mapping of RAM from 64 meg to
786        256 meg to allow operation on boards with larger RAM sizes.
787        * shared/vectors/vectors_init.c: Modified to call 'generic' powerpc
788        vector function (mpc60x_vector_is_valid) instead of MPC750  specific
789        function to allow operation on boards with CPUs other than the
790        MPC750.

793
794        * shared/bootloader/misc.c, shared/console/Makefile.am,
795        shared/console/console.c, shared/console/consoleIo.h,
796        shared/console/inch.c, shared/console/polled_io.c,
797        shared/console/uart.c, shared/console/uart.h, shared/include/bsp.h,
798        shared/irq/Makefile.am, shared/irq/irq.c, shared/irq/irq.h,
799        shared/irq/irq_init.c, shared/openpic/openpic.c,
800        shared/openpic/openpic.h, shared/pci/Makefile.am, shared/pci/pci.c,
801        shared/pci/pci.h, shared/residual/Makefile.am, shared/start/start.S,
802        shared/startup/bspstart.c, shared/vectors/vectors.S,
803        shared/vectors/vectors.h, shared/vectors/vectors_init.c: Per PR216,
804        "libbsp/powerpc/shared" BSP has been modified considerably with the
805        goal to make it more flexible and reusable by other BSPs. The main
806        strategies were: - eliminate hardcoded base addresses; devices use
807        offsets and a BSP defined base address. - separate functionality
808        into different files (e.g. reboot from inch.c to reboot.c) which can
809        be overridden by a 'derived' BSP. - separate initialization code
810        into separate files (e.g.  PCI bridge detection/initialization was
811        separated from the more generic PCI access routines), also to make
812        it easier for 'derived' BSPs to substitute their own initialization
813        code. There are also a couple of enhancements and fixes: - IRQ
814        handling code now has a hook for attaching a VME bridge. - OpenPIC
815        is now explicitely initialized (polarities, senses). Eliminated the
816        implicit assumption on the presence of an ISA PIC. - UART and
817        console driver now supports more than 1 port. The current maximum of
818        2 can easily be extended by enlarging a table (it would even be
819        easier if the ISR API was not broken by design). - fixed polled_io.c
820        so it correctly supports console on COM2 - fixed TLB invalidation
821        code (start.S). - exception handler prints a stack backtrace. -
822        added BSP_pciFindDevice() to scan the pci bus for a particular
823        vendor/device/instance.

8252001-05-09      Joel Sherrill <joel@OARcorp.com>
826
827        * shared/startup/linkcmds: In support of gcc 3.1, added one of more
828        of the sections .jcr, .rodata*, .data.*, .gnu.linkonce.s2.*,
829        .gnu.linkonce.sb2.*, and .gnu.linkonce.s.*.  Spacing corrections and
830        direction of segments to memory regions may also have been
831        addressed.  This was a sweep across all BSPs.
832
8332001-04-08      Joel Sherrill <joel@OARcorp.com>
834
835        * shared/startup/linkcmds: Per PR170, PR171, and PR172 add .eh_frame
836
8372001-03-30      Eric Valette <valette@crf.canon.fr>
838
839        * shared/Makefile.am, shared/console/consoleIo.h,
840        shared/include/bsp.h: These modifications are part of the conversion
841        of the mpc8xx CPU to the "new exception processing model."
842        * configure.in, motorola_powerpc/Makefile.am,
843        motorola_powerpc/configure.in: These modifications are in support of
844        switching the mpc8xx to the use the "new exception processing
845        model."
846
8472000-11-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
848
849        * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
850
8512000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
852
853        * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I
854        $(RTEMS_TOPdir)/aclocal.
855
8562000-11-01      Joel Sherrill <joel@OARcorp.com>
857
858        * shared/startup/bspstart.c: assoc.h, error.h, libio_.h, libio.h,
859        and libcsupport.h moved from libc to lib/include/rtems and now must
860        be referenced as <rtems/XXX.h>.   Header file order was cleaned up
861        while doing this.
862
8632000-10-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
864
865        * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros. Switch to
866        GNU canonicalization.
867
8682000-09-29      Charles-Antoine Gauthier <charles.gauthier@nrc.ca>
869
870        * shared/startup/linkcmds: Added lines so DWARF debug information
871        would be available.  Otherwise gdb complains that the offsets for
872        the debug info are incorrect and doesn't load the files.
873
8742000-09-05      Joel Sherrill <joel@OARcorp.com>
875
876        * shared/start/start.S: Include proper files to compile.
