101
102        * shared/irq/openpic_i8259_irq.c: fixed type of
103        'frame' argument to C_dispatch_irq_handler(). It's
104        really a BSP_Exception_frame*, not a CPU_Interrupt_frame*.
105
1062006-07-12      Till Straumann <strauman@slac.stanford.edu>
107
108        * shared/startup/probeMemEnd.c: added paranoia to inline
109        assembly code; added 'memory' clobbers and made sure
110        any registers modified by the 'asm' appear in the output
111        operands.

122
1232006-06-19      Till Straumann <strauman@slac.stanford.edu>
124
125        * shared/vme/vme_universe.c: Only set/access the
126        _BSP_vme_bridge_irq variable on BSPs that
127        define BSP_PCI_VME_DRIVER_DOES_EOI and BSP_PIC_DO_EOI.
128
1292006-06-19      Till Straumann <strauman@slac.stanford.edu>

133
1342006-06-19      Till Straumann <strauman@slac.stanford.edu>
135
136        * shared/startup/bspstart.c: fixed compiler warnings
137        (bspIo.h inclusion, cast of number constants to pointers).
138        Enable L1 cache on mvme2100.
139
1402006-06-19      Till Straumann <strauman@slac.stanford.edu>
141
142        * shared/irq/irq_asm.S: Never allow the FPU to be switched on
143        for integer-only tasks (new gcc may use FP regs implicitly).
144
1452006-03-08      Joel Sherrill <joel@OARcorp.com>
146
147        * shared/startup/linkcmds: Add .gnu.linkonce.b.* section.
148
1492006-02-13      Till Straumann <strauman@slac.stanford.edu>
150
151        * shared/startup/panic.c, shared/startup/probeMemEnd.c:
152        added code for BSPs to use: panic using printk() to display
153        reason. probeMemEnd() to determine memory size by probing.
154
1552006-02-08      Joel Sherrill <joel@OARcorp.com>

1632006-01-05      Till Straumann <strauman@slac.stanford.edu>
164
165        * shared/vectors/vectors.S: mask high bits when calculating
166        the exception vector number to yield correct result even if
167        the vectors reside in the upper area (0xfff00000; psim).
168
1692005-12-02      Till Straumann <strauman@slac.stanford.edu>
170
171        * shared/irq/irq_init.c, shared/openpic/openpic.h
172        shared/openpic/openpic.c: The 8240's EPIC has a 'serial'
173        mode of operation for multiplexing 16 interrupt lines.
174        This introduces a pipeline delay which can cause
175        spurious interrupts unless ending the interrupt cycle
176        (EOI) is delayed accordingly.
177
1782005-12-01      Till Straumann <strauman@slac.stanford.edu>
179
180        * shared/vectors/vectors.h, shared/vectors/vectors.S,
181        shared/vectors/vectors_init.c: Reduced size of default
182        prologue (some exceptions, e.g., altivec unavail.) are only
183        0x20 bytes apart. Also introduced a modified prologue
184        that switches r0..r3 shadowing off (r0..r3 undefined
185        on certain 603e variants when incurring a TLB miss).
186
1872005-11-29      Till Straumann <strauman@slac.stanford.edu>
188
189        * shared/irq/irq_asm.S, shared/vectors/vectors.S: Clear
190        CR[6] before invoking high-level handler to make sure no
191        varargs fn callee assumes there are FP arguments.
192
1932005-11-29      Till Straumann <strauman@slac.stanford.edu>
194
195        * shared/irq/irq.c: Fixed incorrect removal of first shared
196        interrupt in chain.

220        added getdbat; moved early initialization code (clear_bats) from BSP

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

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

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

7962001-04-08      Joel Sherrill <joel@OARcorp.com>
797
798        * shared/startup/linkcmds: Per PR170, PR171, and PR172 add .eh_frame

801
802        * shared/Makefile.am, shared/console/consoleIo.h,
803        shared/include/bsp.h: These modifications are part of the conversion
804        of the mpc8xx CPU to the "new exception processing model."
805        * configure.in, motorola_powerpc/Makefile.am,
806        motorola_powerpc/configure.in: These modifications are in support of
807        switching the mpc8xx to the use the "new exception processing
808        model."

8102000-11-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
811
812        * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
813
8142000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
815
816        * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I
817        $(RTEMS_TOPdir)/aclocal.
818
8192000-11-01      Joel Sherrill <joel@OARcorp.com>
820
821        * shared/startup/bspstart.c: assoc.h, error.h, libio_.h, libio.h,
822        and libcsupport.h moved from libc to lib/include/rtems and now must
823        be referenced as <rtems/XXX.h>.   Header file order was cleaned up
824        while doing this.
825
8262000-10-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
827
828        * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros. Switch to
829        GNU canonicalization.

8312000-09-29      Charles-Antoine Gauthier <charles.gauthier@nrc.ca>
832
833        * shared/startup/linkcmds: Added lines so DWARF debug information
834        would be available.  Otherwise gdb complains that the offsets for
835        the debug info are incorrect and doesn't load the files.
836
8372000-09-05      Joel Sherrill <joel@OARcorp.com>
838
839        * shared/start/start.S: Include proper files to compile.
840
8412000-08-10      Joel Sherrill <joel@OARcorp.com>

843        * ChangeLog, shared/ChangeLog: New file.
