2
3        * Makefile.am: Install powerpc-utility.h.
4
5        * shared/include/cpuIdent.h, shared/include/cpuIdent.c: Added e200 and
6        e300 features.
7
8        * new-exceptions/cpu.c: Removed PR288 bugfix check.
9
10        * new-exceptions/e500_raw_exc_init.c: Added initialization for e200.
11        Set IVPR register for e200 and e500 to ppc_exc_vector_base.
12
13        * new-exceptions/raw_exception.c, new-exceptions/raw_exception.h: Added
14        vector categories for e200 and e300 cores.  Added global variable
15        ppc_exc_vector_base for CPUs with IVPR register.
16
17        * new-exceptions/bspsupport/ppc_exc.S,
18        new-exceptions/bspsupport/ppc_exc_asm_macros.h,
19        new-exceptions/bspsupport/ppc_exc_bspsupp.h,
20        new-exceptions/bspsupport/ppc_exc_hdl.c,
21        new-exceptions/bspsupport/vectors.h,
22        new-exceptions/bspsupport/vectors_init.c: Conistent code layout in most
23        assember code sections and usage of defines for registers.  Usage of
24        standard header files to avoid multiple definitions.
25       
26        Optimized exception code: Removed many branches and exploit branch
27        prediction for asynchronous exceptions, moved common wrap code into
28        WRAP macro to eliminate branch, static initialization of the handler
29        table with a default handler to eliminate the test if a handler is
30        present.  Register CR6 is no more cleared because the exeption handler
31        functions are not variadic.
32       
33        New method to switch to the interrupt stack. It will be tested if the
34        exception stack pointer is already inside the interrupt stack area.  It
35        is no more necessary to disable interrupts.  The SPRG1 and SPRG2 are
36        used to store the initial interrupt stack pointer and the interrupt
37        stack memory area start.
38
39        Removed variable ppc_exc_msr_irq_mask and use general interrupt disable
40        mask from SPRG0 instead.
41
42        New initialization routine ppc_exc_initialize() for bsp_start().  It
43        takes the interrupt disable mask, interrupt stack start and size as
44        parameters.
45
46        Added packed prologues for CPUs with IVPR and IVOR registers to save
47        memory space.
48
49        Reverted ppc_exc_crit_always_enabled change from yesterday.
50
51        WARNING: Tests with critical interrupt exceptions crash the system at
52        least on MPC8313ERDB and MPC8349EAMDS.  There may be somewhere a
53        serious bug with the new code.
54
552008-07-10      Till Straumann <strauman@slac.stanford.edu>
56
57        * mpc6xx/mmu/pte121.c: use general "memory" clobber
58        rather than memory input operand in inline assembly
59        ("m" doesn't do what the manual says; see discussion
60        on gcc mailing list around 2008/3/30)
61
622008-07-10      Till Straumann <strauman@slac.stanford.edu>
63
64        * ChangeLog, mpc8xx/clock/clock.c, ppc403/clock/clock.c,
65        ppc403/irq/ictrl.h, rtems/powerpc/powerpc.h:
66        Removed all macro definitions which depended on
67        the compiler defining a PPC CPU-model dependent
68        symbol from files in cpukit.
69        Macros which were not used by cpukit have been
70        moved to libcpu/powerpc/rtems/powerpc/powerpc.h.
71
722008-07-10      Till Straumann <strauman@slac.stanford.edu>
73
74        * new-exceptions/bspsupport/README,
75        new-exceptions/bspsupport/ppc_exc.S,
76        new-exceptions/bspsupport/ppc_exc_asm_macros.h,
77        new-exceptions/bspsupport/ppc_exc_bspsupp.h,
78        new-exceptions/bspsupport/ppc_exc_hdl.c,
79        new-exceptions/bspsupport/vectors_init.c:
80        Fixed and enabled stack-switching algorithm which figures out
81        if we already run on the ISR stack rather than relying on the
82        _ISR_Nest_level.
83        Added 'ppc_exc_crit_always_enabled' variable which defines
84        the semantics of critical interrupts.
85        Let asynchronous machine-check handling never call the dispatcher.
86        We don't want to disable MSR_ME ever (to avoid checkstops)
87        and hence asynchronous MEs must not use OS services anyways.
88
892008-07-09      Sebastian Huber <sebastian.huber@embedded-brains.de>
90
91        * shared/include/powerpc-utility.h: Includes standard header files,
92        provides common assembler macros and inline functions for low-level
93        code.
94
952008-05-23      Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>
96
97        * mpc83xx/network/tsec.c:
98        disabled debugging output, reduced rx interrupt coalescing
99
1002008-05-22      Till Straumann <strauman@slac.stanford.edu>
101
102        * ppc403/tty_drv/tty_drv.c, ppc403/console/console405.c:
103        ../ictrl/ictrl.h has gone; include ../irq/ictrl.h
104
1052008-05-16      Joel Sherrill <joel.sherrill@OARcorp.com>
106
107        * mpc83xx/include/mpc83xx.h: or is not a good name for any name in
108        C/C++. See iso646.h for the reason.
109
1102008-05-15      Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>
111
112        * mpc83xx/i2c/mpc83xx_i2cdrv.c:

116
117        * mpc83xx/network/tsec.c, mpc83xx/include/mpc83xx.h:
118        added support for RGMII interface and different board
119

123        * mpc83xx/spi/mpc83xx_spidrv.c, mpc83xx/spi/mpc83xx_spidrv.h:
124        added base frequency into softc structure
125
1262008-05-14      Till Straumann <strauman@slac.stanford.edu>
127
128        * new-exceptions/bspsupport/ppc_exc_bspsupp.h: added
129        comment about the semantics of the return value of
130        ppc_exc_handler_t.
131
1322008-05-14      Till Straumann <strauman@slac.stanford.edu>
133
134        * new-exceptions/bspsupport/irq.c: moved malloc/free
135        outside of irq-protected critical section.
136
1372008-04-24      Joel Sherrill <joel.sherrill@OARcorp.com>
138
139        * mpc8260/console-generic/console-generic.c,
140        mpc8xx/console-generic/console-generic.c: Remove all references to
141        console_reserve_resources and termios_reserve_resources.
142
1432008-04-24      Nigel Spon <nigel@adi.co.nz>
144
145        * ppc403/console/console.c: Correct include path.
146
1472008-04-23      Joel Sherrill <joel.sherrill@OARcorp.com>
148
149        * mpc5xx/console-generic/console-generic.c, mpc5xx/include/console.h,
150        mpc8260/console-generic/console-generic.c, mpc8260/include/console.h,
151        mpc8xx/console-generic/console-generic.c, mpc8xx/include/console.h:
152        Remove all references to console_reserve_resources and
153        termios_reserve_resources.
154
1552008-04-07      Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>
156
157        * README:
158        removed reference to outdated "old-exception-handling" PPC support
159
1602008-03-20      Till Straumann <strauman@slac.stanford.edu>
161
162        * new-exceptions/bspsupport/irq.c: don't disable irqs
163        at the interrupt controller (PIC) during initialization -- this
164        caused problems where some BSPs's BSP_disable_irq_at_pic() routine
165        did not ignore IRQ lines associated with cascaded PICs.
166        Rely on the BSP (BSP_setup_the_pic()) to provide a good
167        initial setup.
168
1692008-03-13      Till Straumann <strauman@slac.stanford.edu>
170
171        * new-exceptions/bspsupport/ppc_exc_asm_macros.h,
172        new-exceptions/bspsupport/ppc_exc.S,
173        new-exceptions/bspsupport/README,
174        new-exceptions/bspsupport/ppc_exc_hdl.c:
175        Thomas Doerfler clarified (thanks!) that raising an
176        exception and executing the 1st instruction is not
177        an atomical operation. I added a fix to the code that
178        checks if a lower-priority interrupt is under way:
179        we now not only test if the 'lock' variable was set
180        but also check if the interrupted PC points to the
181        'write lock' instruction.
182        Added more comments and updated README.
183
1842008-03-11      Till Straumann <strauman@slac.stanford.edu>
185
186        * new-exceptions/bspsupport/ppc_exc_asm_macros.h: bugfix;
187        need to crand not cror when testing lower priority locks
188        during machine-check handling.
189
1902008-03-05      Till Straumann <strauman@slac.stanford.edu>
191
192        * new-exceptions/bspsupport/ppc_exc_asm_macros.h: bugfix;
193        need to andc with irq mask when disabling interrupts.
194
1952008-02-19      Ralf Corsépius <ralf.corsepius@rtems.org>
196
197        * old-exceptions/README, old-exceptions/TODO, old-exceptions/cpu.c,
198        old-exceptions/cpu_asm.S, old-exceptions/irq_stub.S,
199        old-exceptions/ppccache.c, old-exceptions/rtems/score/ppc_offs.h,

202        * Makefile.am: Remove refs to files above.
203        Eliminate OLD_EXCEPTIONS.
204        * configure.ac: Remove OLD_EXCEPTIONS.
205
2062008-02-19      Ralf Corsépius <ralf.corsepius@rtems.org>
207
208        * configure.ac: Deactivate old-exceptions.
209
2102008-02-15      Joel Sherrill <joel.sherrill@OARcorp.com>
211
212        * preinstall.am: Add e500_mmu.h
213
2142008-02-08      Till Straumann <strauman@slac.stanford.edu>
215
216        * Makefile.am, e500/, e500/mmu, e500/mmu/mmu.c,
217        e500/mmu/e500_mmu.h: added code for PPC E500
218        TLB manipulation.
219
2202008-01-10      Till Straumann <strauman@slac.stanford.edu>
221
222        * new-exceptions/bspsupport/irq.c: When unhooking
223        and ISR only disable IRQs at the PIC if we are
224        unhooking the last ISR.
225
2262007-12-11      Till Straumann <strauman@slac.stanford.edu>
227
228        * Makefile.am: don't normally build-in test code
229        (ppc_exc_test.c).
230
2312007-12-11      Till Straumann <strauman@slac.stanford.edu>
232
233        * Makefile.am, new-exceptions/bspsupport/README:
234        provide new irq_bspsupport.rel which was
235        split out of exc_bspsupport.rel to provide finer-grained
236        control over what BSPs want to use.
237
2382007-12-11      Till Straumann <strauman@slac.stanford.edu>
239
240        * new-exceptions/bspsupport/irq.c: enable/disable
241        irq at PIC if an initial handler is present/absent
242        (reproduce traditional semantics).
243
2442007-12-10      Till Straumann <strauman@slac.stanford.edu>
245
246        * new-exceptions/e500_raw_exc_init.c: map DEC
247        exception to ASM_BOOKE_DEC_VECTOR instead of ASM_DEC_VECTOR.
248
249        Fixed wrong mapping of ASM_BOOKE_FIT_VECTOR
250        (was ASM_BOOKE_PIT_VECTOR).
251
2522007-12-10      Till Straumann <strauman@slac.stanford.edu>
253
254        * new-exceptions/raw_exception.c, new_exceptions/raw_exception.h,
255        new_exceptions/bspsupport/irq.c: renamed ASM_BOOKE_PIT_VECTOR
256        to ASM_BOOKE_DEC_VECTOR to be closer to 'official'
257        nomenclature.
258
2592007-12-10      Till Straumann <strauman@slac.stanford.edu>
260
261        * new-exceptions/bspsupport/ppc_exc_test.c: fixed
262        wrong type in argument (signed vs. unsigned)
263        compiler warning.
264
2652007-12-10      Till Straumann <strauman@slac.stanford.edu>
266
267        * Makefile.am: build new-exceptions/bspsupport for
268        non-mpc5xx, new-exception CPUs.
269
2702007-12-10      Till Straumann <strauman@slac.stanford.edu>
271
272        * new-exceptions/bspsupport/nested_irq_test.c: adjusted
273        wrong irq name/number calculation.
274
2752007-12-10      Till Straumann <strauman@slac.stanford.edu>
276
277        * new-exceptions/bspsupport/ppc_exc_hdl.c: make sure
278        RI is set in the exception frame and panic if it isn't
279        (state info might have been lost). This only affects
280        classic PPC.
281
2822007-12-10      Till Straumann <strauman@slac.stanford.edu>
283
284        * new-exceptions/bspsupport/README,
285        new-exceptions/bspsupport/ppc_exc_bspsupp.h
286        new-exceptions/bspsupport/vectors_init.c:
287        added crude test to make sure MMU maps memory as
288        write-back enabled.
289
2902007-12-09      Till Straumann <strauman@slac.stanford.edu>
291
292        * new-exceptions/bspsupport/ppc_exc_test.c,
293        new-exceptions/bspsupport/vectors_init.c,
294        new-exceptions/bspsupport/ppc_exc_bspsupp.h,
295        new-exceptions/bspsupport/README,
296        new-exceptions/bspsupport/irq_supp.h:
297        Added README and some comments; now use TRAP exception
298        in ppc_exc_test.c so that it works on PSIM.
299
3002007-12-08      Till Straumann <strauman@slac.stanford.edu>
301
302        * irq_supp.h: was moved from libbsp/powerpc/shared/irq to
303        libcpu/powerpc/new-exceptions/bspsupport.
304
3052007-12-08      Till Straumann <strauman@slac.stanford.edu>
306
307        * new-exceptions/bspsupport/irq.c,
308        new-exceptions/bspsupport/ppc_exc_bspsupp.h,
309        new-exceptions/bspsupport/ppc_exc_hdl.c:
310        fixed some mismatching signed/unsigned types.
311
3122007-12-08      Till Straumann <strauman@slac.stanford.edu>
313
314        * new-exceptions/bspsupport/, new-exceptions/bspsupport/ppc_exc.S,
315        new-exceptions/bspsupport/ppc_exc_test.c,
316        new-exceptions/bspsupport/vectors.h,
317        new-exceptions/bspsupport/vectors_init.c,
318        new-exceptions/bspsupport/irq.c,
319        new-exceptions/bspsupport/ppc_exc_bspsupp.h,
320        new-exceptions/bspsupport/ppc_exc_hdl.c,
321        new-exceptions/bspsupport/ppc_exc_asm_macros.h,
322        new-exceptions/bspsupport/nested_irq_test.c:
323        New files. Added 'middleware' code for helping BSPs implement
324        exception and interrupt handling and implementing the 'new'
325        RTEMS IRQ API (which I personally dislike).
326
3272007-12-08      Till Straumann <strauman@slac.stanford.edu>
328
329        * new-exceptions/e500_raw_exc_init.c, new-exceptions/raw_exception.c,
330        shared/include/cpuIdent.c, shared/include/cpuIdent.h:
331        Added different kinds of 'bookE' to the ppc_cpu_is_bookE feature
332        check; unfortunately...
333
3342007-12-07      Till Straumann <strauman@slac.stanford.edu>
335
336        * Makefile.am: must not add e500_raw_exc_init.c to
337        xyz_SOURCES for mpc5xx
338
3392007-12-06      Till Straumann <strauman@slac.stanford.edu>
340
341        * shared/include/cpuIdent.h, shared/include/cpuIdent.c:
342        added feature check for 603 'TLBMISS exception GPRS shadowing'.
343
3442007-12-06      Till Straumann <strauman@slac.stanford.edu>
345
346        * new-exceptions/raw_exception.c, new-exceptions/raw_exception.h:
347        Removed all #ifdef <cpu_flavor>. All exception vectors are now
348        always defined.
349        Changed implementation of <cpu>_vector_is_valid() from 'case'
350        statements to table lookup.
351        Replaced 'ASM_VECTORS_CRITICAL' by a variable
352        'bsp_raw_vector_is_405_critical' which is set at run-time.
353        Removed PPC_MSR_EXC_BITS. The exception handling code
354        (libbsp/shared/vectors/vectors.S and ../irq/irq_asm.S) now
355        has a run-time check for these bits.
356        Both files are now free of #if <cpu_flavor> constructs.
357
3582007-12-05      Till Straumann <strauman@slac.stanford.edu>
359
360        * Makefile.am, configure.ac, preinstall.am,
361        new-exceptions/e500_raw_exc_init.c: Started adding
362        support for e500 CPU. Most stuff is borrowed from mpc6xx.
363
3642007-12-05      Till Straumann <strauman@slac.stanford.edu>
365
366        * rtems/powerpc/powerpc.h: added a #ifdef __ppc_generic
367        branch. The goal is eventually to make this the starting
368        point for cleanup (remove as many branches as possible;
369        replace by run-time tests if necessary).
370
3712007-12-05      Joel Sherrill <joel.sherrill@OARcorp.com>
372
373        * new-exceptions/raw_exception.c: Conditionalize call to
374        e500_setup_raw_exceptions() since that is not even in the tree yet.
375
3762007-12-05      Joel Sherrill <joel.sherrill@OARcorp.com>
377
378        * new-exceptions/raw_exception.c: Conditionalize some BOOKE vectors.
379
3802007-12-05      Till Straumann <strauman@slac.stanford.edu>
381
382        * new-exceptions/raw_exception.c, new-exceptions/raw_exception.h:
383        Added typedef for exception classes (classic, critical, ...
384        synchronous / asynchronous). ppc_vector_is_valid() now returns
385        the appropriate class.
386
3872007-12-05      Till Straumann <strauman@slac.stanford.edu>
388
389        * new-exceptions/raw_exception.c: made all <cpu>_vector_is_valid()
390        subroutines that are called from ppc_vector_is_valid() 'static'.
391
3922007-12-05      Till Straumann <strauman@slac.stanford.edu>
393
394        * new-exceptions/raw_exception.c, new-exceptions/raw_exception.h:
395        Qualified all exception vector symbols that are only defined
396        #ifdef <cpu_flavor> with <cpu_flavor> in the symbol name.
397        If the special flavor __ppc_generic is effective the ALL
398        vector symbols are available and ppc_vector_is_valid() works
399        for all supported CPUs (run-time check).
400        This is work towards a #ifdef <cpu_flavor> free libcpu and

459        not check for a particular CPU type if possible but
460        check the respective feature bit (e.g., 'has_altivec').
461        This makes it much less cumbersome to add more CPU
462        types in the future.

1633        * configure.ac: Delete the commented out line that said that the

1711
1712        * mpc8xx/console-generic/console-generic.c: Bug found by Yacine
1713        <elkolli@crf.canon.fr> where the initialization or irq data
1714        structure was incomplete in case a SMC channel was used first and
1715        later a SCC one.

17172001-05-17      Joel Sherrill <joel@OARcorp.com>
1718
1719        * mpc6xx/exceptions/raw_exception.c, pc6xx/mmu/pte121.c: Modified
1720        slightly to reflect recent PowerPC re-organization and avoid
1721        warnings.
1722
17232001-05-15      Till Straumann <strauman@slac.stanford.edu>
1724
1725        * mpc6xx/mmu/pte121.c, mpc6xx/mmu/pte121.h: New files. Missed in

17282001-05-14      Till Straumann <strauman@slac.stanford.edu>
1729
1730        * rtems/powerpc/registers.h, rtems/score/ppc.h: Per PR213, add  the
1731        following: - support for the MPC74000 (AKA G4); there is no AltiVec
1732        support yet, however. - the cache flushing assembly code uses
1733        hardware-flush on the G4. Also, a couple of hardcoded numerical
1734        values were replaced by more readable symbolic constants. - extended
1735        interrupt-disabled code section so enclose the entire cache
1736        flush/invalidate procedure (as recommended by the book). This is not
1737        (latency) critical as it is only used by init code but prevents
1738        possible corruption. - Trivial page table support as been added.
1739        (1:1 effective-virtual-physical address mapping which is only useful
1740        only on CPUs which feature hardware TLB replacement, e.g. >604.
1741        This allows for write-protecting memory regions, e.g. text/ro-data
1742        which makes catching corruptors a lot easier. It also frees one
1743        DBAT/IBAT and gives more flexibility for setting up address maps :
1744        -) - setdbat() allows changing BAT0 also (since the BSP may use a
1745        page table, BAT0 could be available...). - asm_setdbatX() violated
1746        the SVR ABI by using r20 as a scratch register; changed for r0 -
1747        according to the book, a context synchronizing instruction is
1748        necessary prior to and after changing a DBAT -> isync added
1749        * new-exceptions/cpu.c: Per PR211 fix saving/restoring floating
1750        point context.  The fpsave and fprestore routines are only used in a
1751        executing context which _is_ fp and hence has the FPU enabled. The
1752        current behavior required the FPU always to be on which is very
1753        dangerous if lazy context switching is used.   [Joel Note: Some
1754        ports explicitly enabled the FPU in the FP save and restore routines
1755        to avoid this.] The patch also makes sure (on powerpc only) that the
1756        FPU is disabled for integer tasks. Note that this is crucial if
1757        deferred fp context switching is used. Otherwise, fp context
1758        corruption may go undetected! Also note that even tasks which merely
1759        push/pop FP registers to/from the stack without modifying them still
1760        MUST be FP tasks - otherwise (if lazy FP context switching is used),
1761        FP register corruption (of other, FP, tasks may occur)! Furthermore,
1762        (on PPC) by default, lazy FP context save/restore is _disabled_.
1763        * shared/include/io.h: Per PR215 address the following issues: -
1764        _IO_BASE, _ISA_MEM_BASE and PCI_DRAM_OFFSET are no longer defined by
1765        libcpu (powerpc/shared/include/io.h) but by the BSP (who is the only
1766        one to know the values) - the affected BSP (shared/motorola) headers
1767        have been fixed in a separate "libbsp/powerpc/shared" patch. - the
1768        DEC 21140 driver (libchip/network/dec21140.c) has been fixed to use
1769        PCI_DRAM_OFFSET instead of PREP_PCI_DRAM_OFFSET. and PCI_MEM_BASE
1770        instead of PREP_ISA_MEM_BASE. PCI_MEM_BASE is to be defined by the
1771        BSP who is using this driver. - the DEC driver also has been fixed
1772        to use the newer rtems_bsp_delay_in_bus_cycles() instead of the
1773        obsolete delay_in_bus_cycles().

17752001-05-14      Joel Sherrill <joel@OARcorp.com>
1776
1777        * shared/include/cpuIdent.c: Account for duplicate numbers.
1778
17792001-04-17      Joel Sherrill <joel@OARcorp.com>
1780
1781        * shared/include/cpu.h: Added ifndef ASM.
1782
17832001-04-03      Joel Sherrill <joel@OARcorp.com>
1784
1785        * Closed PR57.  The hack is OK as it allows a BSP to override or not
1786        at its discretion.
1787        * Per PR94, all rtems/score/CPUtypes.h are named
1788        rtems/score/types.h.
1789        * Per PR94, all rtems/score/CPUtypes.h are named
1790        rtems/score/types.h.
1791        * mpc8xx/timer/timer.c: Removed #warning declaring providing a
1792        default definition for the macros
1793        rtems_cpu_configuration_get_timer_least_valid and
1794        rtems_cpu_configuration_get_timer_average_overhead.
1795        * old-exceptions/rtems/score/cpu.h,
1796        new-exceptions/rtems/score/cpu.h: Account for name change.
1797
17982001-03-30      Eric Valette <valette@crf.canon.fr>
1799
1800        * mpc8xx/vectors/Makefile.am,
1801        mpc8xx/vectors/README, mpc8xx/vectors/align_h.S
1802        mpc8xx/vectors/vectors.S: These files were removed in support of
1803        switching the mpc8xx to the use the "new exception processing
1804        model."
1805        * configure.in, mpc6xx/mmu/bat.h, mpc8xx/Makefile.am,
1806        mpc8xx/clock/clock.c, mpc8xx/console-generic/console-generic.c,
1807        mpc8xx/include/mpc8xx.h, mpc8xx/mmu/mmu.c,
1808        new_exception_processing/cpu.h, shared/include/byteorder.h,
1809        wrapup/Makefile.am: This is conversion of the mpc8xx CPU to the "new
1810        exception processing model."
1811        * mpc8xx/exceptions/Makefile.am,
1812        mpc8xx/exceptions/asm_utils.S, mpc8xx/exceptions/raw_exception.c,
1813        mpc8xx/exceptions/raw_exception.h: New files.

1818        mpc6xx/exceptions/Makefile.am, mpc6xx/mmu/Makefile.am,
1819        mpc8xx/include/Makefile.am, new_exception_processing/Makefile.am,
1820        old_exception_processing/Makefile.am, pc403/ictrl/Makefile.am,
1821        shared/include/Makefile.am, shared/src/Makefile.am: Apply *_HEADERS
1822        instead of *H_FILES.
1823
18242001-01-03      Joel Sherrill <joel@OARcorp.com>
1825
1826        * new_exception_processing/cpu.h, old_exception_processing/cpu.c:
1827        old_exception_processing/cpu.h, Added _CPU_Initialize_vectors(). In
1828        particular, spurious vector initialization had to be moved on old
1829        exception processing model.
1830
18312000-11-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
1832
1833        * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
1834
18352000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
1836
1837        * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I
1838        $(RTEMS_TOPdir)/aclocal.
1839
18402000-10-26      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
1841
1842        * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros. Switch to
1843        GNU canonicalization.
1844
18452000-10-20      Joel Sherrill <joel@OARcorp.com>
1846
1847        * mpc8xx/console-generic/console-generic.c: Avoid use of BSP
1848        definitions and rely on the new routine
1849        mbx8xx_console_get_configuration() to get information.  This routine
1850        was formerly incorrectly called
1851        mbx8xx_console_use_maximum_buffer_size(). binding to the exception
1852        code.
1853        * configure.in, Makefile.am: Explicitly specify whether an
1854        RTEMS_CPU_MODEL is using old or new exception processing.  This is
1855        important because when building multilib, you do not know  the
1856        RTEMS_CPU_MODEL.  So everything built in a multilib'ed RTEMS must be
1857        independent of the exception model and allow for late binding to the
1858        exception code.
1859
18602000-10-18      Sergei Organov <osv@javad.ru>
1861
1862        * Added full support for MPC505.
1863        * configure.in, mpc505/Makefile.am: Modified to reflect ictrl
1864        addition.
1865        * old_exception_processing/Makefile.am: Account for ppc_offs.h.
1866        * old_exception_processing/cpu_asm.S: Offsets moved to ppc_offs.h.
1867        * mpc505/timer/timer.c: Use <rtems.h>, not "rtems.h".
1868        * mpc505/vectors/vectors.S: Now use constants for exception numbers.
1869        * mpc505/ictrl: New directory.
1870        * old_exception_processing/ppc_offs.h: New file.
1871        * old_exception_processing/cpu.h: Make Nest and Disable levels
1872        volatile.
1873        * mpc505/vectors/Makefile.am: alignment exception handler now
1874        included.
1875        * mpc505/ictrl/Makefile.am,
1876        mpc505/ictrl/ictrl.c, mpc505/ictrl/ictrl.h: New files.

18782000-10-18      Joel Sherrill <joel@OARcorp.com>
1879
1880        * mpc8xx/console-generic/console-generic.c: Removed include of
1881        <bsp.h> by adding BSP dependent routine
1882        mbx8xx_console_use_maximum_buffer_size() which can be hard coded or
1883        check non-volatile memory for configuration.
1884        * mpc8xx/console-generic/console-generic.c: Removed warnings.
1885        * mpc6xx/clock/c_clock.h: Removed commented out reference to
1886        <bsp.h>.
1887        * mpc6xx/timer/timer.c, mpc6xx/timer/timer.c: Ditto.
1888        * mpc6xx/clock/c_clock.c, mpc6xx/clock/c_clock.h: Removed use of
1889        bsp.h and replaced it with use of proper interfaces or explicit
1890        externs of required functions and data.
1891
18922000-09-04      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

19072000-08-11      Charles-Antoine Gauthier  <charles.gauthier@nrc.ca>
1908
1909        * mpc8xx/console-generic/console-generic.c: Add support for
1910        configuration parameters in NVRAM
1911
19122000-08-10      Charles-Antoine Gauthier  <charles.gauthier@nrc.ca>
1913
1914        * mpx8xx/console-generic/console-generic.c(m8xx_uart_pollWrite):
1915        Flush actual buffer.
1916        * mpx8xx/console-generic/console-generic.c: Addition of support for
1917        shared printk and no termios.
1918
19192000-06-08      Eric Valette <valette@crf.canon.fr>
1920
1921        * mpc8xx/console-generic/console-generic.c: The printk/printf did
1922        not work when loaded by EPPCBUG. They did work when loaded with the
1923        BDM debugger.  I suspected EPPBUG  made some nasty things like
1924        patching Communication processor microcode...  Anyway, the attached
1925        patch: 1) Enables to have printk nearly immediately after boot, 2)
1926        Make printf work automagically (I do not know why except I make a
1927        different initialization for printk that should be overwritten by
1928        console init later ?) I let the default to be using EPPCBUG embedded
1929        firmware to boot and  using this printk early enabler code
1930        (LOADED_BY_EPPCBUG and  EARLY_CONSOLE) are on.
