133
134        * shared/irq/openpic_i8259_irq.c: fixed type of
135        'frame' argument to C_dispatch_irq_handler(). It's

137
1382006-07-12      Till Straumann <strauman@slac.stanford.edu>
139
140        * shared/startup/probeMemEnd.c: added paranoia to inline

156
157        * shared/vme/vme_universe.c: Only set/access the
158        _BSP_vme_bridge_irq variable on BSPs that
159        define BSP_PCI_VME_DRIVER_DOES_EOI and BSP_PIC_DO_EOI.

167
168        * shared/startup/bspstart.c: fixed compiler warnings
169        (bspIo.h inclusion, cast of number constants to pointers).
170        Enable L1 cache on mvme2100.
171
1722006-06-19      Till Straumann <strauman@slac.stanford.edu>
173
174        * shared/irq/irq_asm.S: Never allow the FPU to be switched on
175        for integer-only tasks (new gcc may use FP regs implicitly).
176
1772006-03-08      Joel Sherrill <joel@OARcorp.com>
178
179        * shared/startup/linkcmds: Add .gnu.linkonce.b.* section.
180
1812006-02-13      Till Straumann <strauman@slac.stanford.edu>
182
183        * shared/startup/panic.c, shared/startup/probeMemEnd.c:
184        added code for BSPs to use: panic using printk() to display
185        reason. probeMemEnd() to determine memory size by probing.
186
1872006-02-08      Joel Sherrill <joel@OARcorp.com>

196
197        * shared/vectors/vectors.S: mask high bits when calculating
198        the exception vector number to yield correct result even if
199        the vectors reside in the upper area (0xfff00000; psim).

202
203        * shared/irq/irq_init.c, shared/openpic/openpic.h
204        shared/openpic/openpic.c: The 8240's EPIC has a 'serial'
205        mode of operation for multiplexing 16 interrupt lines.
206        This introduces a pipeline delay which can cause
207        spurious interrupts unless ending the interrupt cycle
208        (EOI) is delayed accordingly.
209
2102005-12-01      Till Straumann <strauman@slac.stanford.edu>
211
212        * shared/vectors/vectors.h, shared/vectors/vectors.S,

214        prologue (some exceptions, e.g., altivec unavail.) are only
215        0x20 bytes apart. Also introduced a modified prologue
216        that switches r0..r3 shadowing off (r0..r3 undefined
217        on certain 603e variants when incurring a TLB miss).
218
2192005-11-29      Till Straumann <strauman@slac.stanford.edu>
220
221        * shared/irq/irq_asm.S, shared/vectors/vectors.S: Clear
222        CR[6] before invoking high-level handler to make sure no
223        varargs fn callee assumes there are FP arguments.
224
2252005-11-29      Till Straumann <strauman@slac.stanford.edu>
226
227        * shared/irq/irq.c: Fixed incorrect removal of first shared

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

267
268        PR 833/bsps
269        * shared/irq/irq_asm.S: Currently, all (new exception) BSPs
270        explicitely enable the FPU across the user ISR but DONT save/restore
271        the FPU context. Any use of the FPU fron the user handler (e.g., due
272        to GCC optimizations) result in corruption. The fix results in an
273        exception in such cases (user ISR must explicitely
274        save/enable/restore FPU).

780        * shared/start/start.S: Increased BAT0 mapping of RAM from 64 meg to
781        256 meg to allow operation on boards with larger RAM sizes.
782        * shared/vectors/vectors_init.c: Modified to call 'generic' powerpc
783        vector function (mpc60x_vector_is_valid) instead of MPC750  specific
784        function to allow operation on boards with CPUs other than the
785        MPC750.

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

821
822        * shared/startup/linkcmds: In support of gcc 3.1, added one of more
823        of the sections .jcr, .rodata*, .data.*, .gnu.linkonce.s2.*,
824        .gnu.linkonce.sb2.*, and .gnu.linkonce.s.*.  Spacing corrections and
825        direction of segments to memory regions may also have been
826        addressed.  This was a sweep across all BSPs.

830        * shared/startup/linkcmds: Per PR170, PR171, and PR172 add .eh_frame

833
834        * shared/Makefile.am, shared/console/consoleIo.h,
835        shared/include/bsp.h: These modifications are part of the conversion
836        of the mpc8xx CPU to the "new exception processing model."
837        * configure.in, motorola_powerpc/Makefile.am,
838        motorola_powerpc/configure.in: These modifications are in support of
839        switching the mpc8xx to the use the "new exception processing
840        model."

843
844        * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
845
8462000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
847
848        * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I
849        $(RTEMS_TOPdir)/aclocal.
850
8512000-11-01      Joel Sherrill <joel@OARcorp.com>
852
853        * shared/startup/bspstart.c: assoc.h, error.h, libio_.h, libio.h,
854        and libcsupport.h moved from libc to lib/include/rtems and now must
855        be referenced as <rtems/XXX.h>.   Header file order was cleaned up
856        while doing this.

864
865        * shared/startup/linkcmds: Added lines so DWARF debug information
866        would be available.  Otherwise gdb complains that the offsets for
867        the debug info are incorrect and doesn't load the files.
