27
282001-04-03      Joel Sherrill <joel@OARcorp.com>

33        default definition for the macros

125
126        * configure.ac: Remove mpc750 from new_exception_processing,
127        Remove mpc604 from new_exception_processing.
128
1292001-11-21      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
130
131        * configure.ac: Remove ppc603e from old_exception_processing.

140
1412001-11-20      Joel Sherrill <joel@OARcorp.com>
142
143        * ChangeLog: Corrected spacing.
144
1452001-11-14      Till Straumann <strauman@SLAC.Stanford.EDU>
146
147        * new_exception_processing/cpu_asm.S: Support double or single
148        precision context switches.  Note that doing a single precision
149        context save/restore on a double precision PowerPC machine does not
150        only result in rounding errors but also screws up the FPSCR register!
151
1522001-11-08      Dennis Ehlin (ECS) <Dennis.Ehlin@ecs.ericsson.se>
153
154        This modification is part of the submitted modifications necessary to
155        support the IBM PPC405 family.  This submission was reviewed by
156        Thomas Doerfler <Thomas.Doerfler@imd-systems.de> who ensured it did
157        not negatively impact the ppc403 BSPs.  The submission and tracking
158        process was captured as PR50.
159        * ppc403/console/console405.c ppc403/tty_drv/.cvsignore,
160        ppc403/tty_drv/Makefile.am, ppc403/tty_drv/tty_drv.c,
161        ppc403/tty_drv/tty_drv.h: New files.

166        ppc403/timer/timer.c: Modified.
167
1682001-11-07      Joel Sherrill <joel@OARcorp.com>
169
170        * configure.ac: Delete the commented out line that said that
171        the mpc8260 used the old exception processing model.  This line
172        also appears to have caused ppc603e to miss this test.
173
1742001-10-29      Joel Sherrill <joel@OARcorp.com>
175
176        * mpc8xx/timer/timer.c: Added hack for two macros that are not defined
177        with the new exception processing model:
178                rtems_cpu_configuration_get_timer_least_valid()
179                rtems_cpu_configuration_get_timer_average_overhead()
180        This is captured as PR57.

240        Renamed delay_in_bus_cycles() to rtems_bsp_delay_in_bus_cycles().
241
2422001-09-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
243
244        * new_exception_processing/Makefile.am: Use 'PREINSTALL_FILES ='.
245        * old_exception_processing/Makefile.am: Use 'PREINSTALL_FILES ='.
246        * mpc6xx/mmu/Makefile.am: Use 'PREINSTALL_FILES ='.
247        * mpc6xx/clock/Makefile.am: Use 'PREINSTALL_FILES ='.
248        * mpc6xx/exceptions/Makefile.am: Use 'PREINSTALL_FILES ='.

252        * shared/src/Makefile.am: Use 'PREINSTALL_FILES ='.
253        * shared/src/Makefile.am: Use 'CLEANFILES ='.
254
2552000-06-08      Eric Valette <valette@crf.canon.fr>
256
257        * mpc8xx/console-generic/console-generic.c:
258        The printk/printf did not work when loaded by EPPCBUG. They did
259        work when loaded with the BDM debugger.  I suspected EPPBUG
260        made some nasty things like patching Communication processor
261        microcode...  Anyway, the attached patch:
262          1) Enables to have printk nearly immediately after boot,
263          2) Make printf work automagically (I do not know why except I make a
264        different initialization for printk that should be overwritten by
265        console init later ?)
266
267        I let the default to be using EPPCBUG embedded firmware to boot and
268        using this printk early enabler code (LOADED_BY_EPPCBUG and
269        EARLY_CONSOLE) are on.
270
2712001-05-24      Tom Armistead <tom_armistead@phx.mcd.mot.com>
272
273        * mpc6xx/timer/timer.c: Added include of bsp.h and removed
274        external declaration of BSP_Convert_decrementer() to
275        correct unresolved reference to this routine.
276
2772001-05-24      Eric Valette <valette@crf.canon.fr>
278
279        * mpc8xx/console-generic/console-generic.c: Bug found by Yacine
280        <elkolli@crf.canon.fr> where the initialization or irq data structure
281        was incomplete in case a SMC channel was used first and later a SCC one.
282
2832001-03-30      Eric Valette <valette@crf.canon.fr>
284
285        * mpc8xx/vectors/.cvsignore, mpc8xx/vectors/Makefile.am,
286        mpc8xx/vectors/README, mpc8xx/vectors/align_h.S
287        mpc8xx/vectors/vectors.S:  These files were removed in
288        support of switching the mpc8xx to the use the "new exception
289        processing model."
290
2912001-03-30      Eric Valette <valette@crf.canon.fr>

299        mpc8xx/include/mpc8xx.h, mpc8xx/mmu/mmu.c,
300        new_exception_processing/cpu.h, shared/include/byteorder.h,
301        wrapup/Makefile.am:  This is conversion of the
302        mpc8xx CPU to the "new exception processing model."

315
316        * new_exception_processing/cpu.h, old_exception_processing/cpu.c:
317        old_exception_processing/cpu.h, Added _CPU_Initialize_vectors().
318        In particular, spurious vector initialization had to be moved
319        on old exception processing model.
320
3212000-11-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
322
323        * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
324
3252000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
326
327        * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I $(RTEMS_TOPdir)/aclocal.
328
3292000-10-26      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
330
331        * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros.
332        Switch to GNU canonicalization.
333
3342000-10-20      Joel Sherrill <joel@OARcorp.com>
335
336        * mpc8xx/console-generic/console-generic.c: Avoid use of
337        BSP definitions and rely on the new routine
338        mbx8xx_console_get_configuration() to get information.  This
339        routine was formerly incorrectly called
340        mbx8xx_console_use_maximum_buffer_size().
341        binding to the exception code.
342
3432000-10-20      Joel Sherrill <joel@OARcorp.com>
344
345        * configure.in, Makefile.am: Explicitly specify whether an
346        RTEMS_CPU_MODEL is using old or new exception processing.  This
347        is important because when building multilib, you do not know
348        the RTEMS_CPU_MODEL.  So everything built in a multilib'ed RTEMS
349        must be independent of the exception model and allow for late
350        binding to the exception code.

369        * mpc8xx/console-generic/console-generic.c: Removed include of
370        <bsp.h> by adding BSP dependent routine

386        bsp.h and replaced it with use of proper interfaces or explicit
387        externs of required functions and data.
