97
98        * shared/irq/openpic_i8259_irq.c: fixed type of
99        'frame' argument to C_dispatch_irq_handler(). It's

101
1022006-07-12      Till Straumann <strauman@slac.stanford.edu>
103
104        * shared/startup/probeMemEnd.c: added paranoia to inline

107        operands.

118
1192006-06-19      Till Straumann <strauman@slac.stanford.edu>
120
121        * shared/vme/vme_universe.c: Only set/access the
122        _BSP_vme_bridge_irq variable on BSPs that
123        define BSP_PCI_VME_DRIVER_DOES_EOI and BSP_PIC_DO_EOI.
124
1252006-06-19      Till Straumann <strauman@slac.stanford.edu>

129
1302006-06-19      Till Straumann <strauman@slac.stanford.edu>
131
132        * shared/startup/bspstart.c: fixed compiler warnings
133        (bspIo.h inclusion, cast of number constants to pointers).
134        Enable L1 cache on mvme2100.
135
1362006-06-19      Till Straumann <strauman@slac.stanford.edu>
137
138        * shared/irq/irq_asm.S: Never allow the FPU to be switched on
139        for integer-only tasks (new gcc may use FP regs implicitly).
140
1412006-03-08      Joel Sherrill <joel@OARcorp.com>
142
143        * shared/startup/linkcmds: Add .gnu.linkonce.b.* section.
144
1452006-02-13      Till Straumann <strauman@slac.stanford.edu>
146
147        * shared/startup/panic.c, shared/startup/probeMemEnd.c:
148        added code for BSPs to use: panic using printk() to display
149        reason. probeMemEnd() to determine memory size by probing.
150
1512006-02-08      Joel Sherrill <joel@OARcorp.com>
152

158
1592006-01-05      Till Straumann <strauman@slac.stanford.edu>
160
161        * shared/vectors/vectors.S: mask high bits when calculating
162        the exception vector number to yield correct result even if
163        the vectors reside in the upper area (0xfff00000; psim).
164
1652005-12-02      Till Straumann <strauman@slac.stanford.edu>
166
167        * shared/irq/irq_init.c, shared/openpic/openpic.h
168        shared/openpic/openpic.c: The 8240's EPIC has a 'serial'
169        mode of operation for multiplexing 16 interrupt lines.
170        This introduces a pipeline delay which can cause
171        spurious interrupts unless ending the interrupt cycle
172        (EOI) is delayed accordingly.
173
1742005-12-01      Till Straumann <strauman@slac.stanford.edu>
175
176        * shared/vectors/vectors.h, shared/vectors/vectors.S,
177        shared/vectors/vectors_init.c: Reduced size of default
178        prologue (some exceptions, e.g., altivec unavail.) are only
179        0x20 bytes apart. Also introduced a modified prologue
180        that switches r0..r3 shadowing off (r0..r3 undefined
181        on certain 603e variants when incurring a TLB miss).
182
1832005-11-29      Till Straumann <strauman@slac.stanford.edu>
184
185        * shared/irq/irq_asm.S, shared/vectors/vectors.S: Clear
186        CR[6] before invoking high-level handler to make sure no
187        varargs fn callee assumes there are FP arguments.
188
1892005-11-29      Till Straumann <strauman@slac.stanford.edu>
190
191        * shared/irq/irq.c: Fixed incorrect removal of first shared

214        shared/startup/bspstart.c: moved assembly code to C; setdbat now
215        supports high bats on 7450 CPUs; added argument checking to setdbat;
216        added getdbat; moved early initialization code (clear_bats) from BSP
217        to libcpu (CPU_clear_bats_early)

231
232        PR 833/bsps
233        * shared/irq/irq_asm.S: Currently, all (new exception) BSPs
234        explicitely enable the FPU across the user ISR but DONT save/restore
235        the FPU context. Any use of the FPU fron the user handler (e.g., due
236        to GCC optimizations) result in corruption. The fix results in an
237        exception in such cases (user ISR must explicitely
238        save/enable/restore FPU).

760        shared/pci/pci.h, shared/residual/Makefile.am, shared/start/start.S,
761        shared/startup/bspstart.c, shared/vectors/vectors.S,
762        shared/vectors/vectors.h, shared/vectors/vectors_init.c: Per PR216,
763        "libbsp/powerpc/shared" BSP has been modified considerably with the
764        goal to make it more flexible and reusable by other BSPs. The main
765        strategies were: - eliminate hardcoded base addresses; devices use
766        offsets and a BSP defined base address. - separate functionality
767        into different files (e.g. reboot from inch.c to reboot.c) which can
768        be overridden by a 'derived' BSP. - separate initialization code
769        into separate files (e.g.  PCI bridge detection/initialization was
770        separated from the more generic PCI access routines), also to make
771        it easier for 'derived' BSPs to substitute their own initialization
772        code. There are also a couple of enhancements and fixes: - IRQ
773        handling code now has a hook for attaching a VME bridge. - OpenPIC
774        is now explicitely initialized (polarities, senses). Eliminated the
775        implicit assumption on the presence of an ISA PIC. - UART and
776        console driver now supports more than 1 port. The current maximum of
777        2 can easily be extended by enlarging a table (it would even be
778        easier if the ISR API was not broken by design). - fixed polled_io.c
779        so it correctly supports console on COM2 - fixed TLB invalidation
780        code (start.S). - exception handler prints a stack backtrace. -
781        added BSP_pciFindDevice() to scan the pci bus for a particular
782        vendor/device/instance.

785
786        * shared/startup/linkcmds: In support of gcc 3.1, added one of more
787        of the sections .jcr, .rodata*, .data.*, .gnu.linkonce.s2.*,
788        .gnu.linkonce.sb2.*, and .gnu.linkonce.s.*.  Spacing corrections and
789        direction of segments to memory regions may also have been
790        addressed.  This was a sweep across all BSPs.

7922001-04-08      Joel Sherrill <joel@OARcorp.com>
793
794        * shared/startup/linkcmds: Per PR170, PR171, and PR172 add .eh_frame
795
7962001-03-30      Eric Valette <valette@crf.canon.fr>
797
798        * shared/Makefile.am, shared/console/consoleIo.h,
799        shared/include/bsp.h: These modifications are part of the conversion
800        of the mpc8xx CPU to the "new exception processing model."
801        * configure.in, motorola_powerpc/Makefile.am,
802        motorola_powerpc/configure.in: These modifications are in support of
803        switching the mpc8xx to the use the "new exception processing
804        model."

8062000-11-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
807
808        * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
809
8102000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
811
812        * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I
813        $(RTEMS_TOPdir)/aclocal.
814
8152000-11-01      Joel Sherrill <joel@OARcorp.com>
816
817        * shared/startup/bspstart.c: assoc.h, error.h, libio_.h, libio.h,
818        and libcsupport.h moved from libc to lib/include/rtems and now must
819        be referenced as <rtems/XXX.h>.   Header file order was cleaned up
820        while doing this.
821
8222000-10-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
823
824        * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros. Switch to
825        GNU canonicalization.
826
8272000-09-29      Charles-Antoine Gauthier <charles.gauthier@nrc.ca>
828
829        * shared/startup/linkcmds: Added lines so DWARF debug information
830        would be available.  Otherwise gdb complains that the offsets for
831        the debug info are incorrect and doesn't load the files.
832
8332000-09-05      Joel Sherrill <joel@OARcorp.com>
834
835        * shared/start/start.S: Include proper files to compile.
836
8372000-08-10      Joel Sherrill <joel@OARcorp.com>
838
839        * ChangeLog, shared/ChangeLog: New file.
