592008-07-22      Till Straumann <strauman@slac.stanford.edu>
60
61        * ppc403/clock/clock.c: Added (conditionally compiled)
62        code so that a BSP can choose to hook the timer exception
63        directly rather than going through the interrupt dispatcher.
64
652008-07-21      Till Straumann <strauman@slac.stanford.edu>
66
67        * new-exceptions/raw_exception,h,

70       
712008-07-18      Sebastian Huber <sebastian.huber@embedded-brains.de>
72
73        * shared/include/powerpc-utility.h: Changed special purpose register
74        inline functions to macros.  Added macros to set and clear bits for
75        SPRs and DCRs.
76
77        * new-exceptions/raw_exception.c: The watchdog exception for e200 is

81
82        * mpc55xx/include/watchdog.h: New file.
83
84        * Makefile.am: Install mpc55xx/include/watchdog.h for MPC55XX.
85
862008-07-18      Thomas Doerfler <thomas.doerfler@embedded-brains.de>
87
88        * mpc83xx/network/tsec.c: Initialize PHY registers late enough,
89        so that phy access is possible
90
912008-07-17      Thomas Doerfler <thomas.doerfler@embedded-brains.de>
92
93        * rtems/powerpc/powerpc.h:
94        ppc405 uses definitions distinct from ppc403 now
95        * shared/src/cache_.h: Use correct powerpc.h to get cache attributes
96
97       
982008-07-17      Thomas Doerfler <thomas.doerfler@embedded-brains.de>
99
100        * shared/include/powerpc-utility.h:
101        Fixed typo in access macros for device control registers (DCR)
102       
1032008-07-16      Till Straumann <strauman@slac.stanford.edu>
104
105        * new-exceptions/bspsupport/vectors_init.c: added
106        features to C_exception_handler() (the default global
107        handler):
108         - try to catch recursion
109         - print info about context where the exception occurred
110           (ISR or task with task ID).
111         - suspend offending task rather than spinning forever.
112       
1132008-07-16      Till Straumann <strauman@slac.stanford.edu>
114
115        * new-exceptions/bspsupport/vectors_init.c: must not
116        align start of stack downwards (we don't 'own' memory
117        below start). Instead, use original boundaries but
118        align the stack pointer as required.
119
120        Added test to verify that R13 was loaded with _SDA_BASE_
121        during early initialization (low-level assembly code
122        relies on it).
123
1242008-07-16      Till Straumann <strauman@slac.stanford.edu>
125
126        * new-exceptions/cpu.c: propagate R2 to all task contexts
127        even if the ABI is SVR4. Cannot hurt...
128
1292008-07-16      Till Straumann <strauman@slac.stanford.edu>
130
131        * new-exceptions/cpu.c: use ppc_interrupt_get_disable_mask()
132        to determine which bits to set/clear from _CPU_Context_Initialize().
133
1342008-07-16      Till Straumann <strauman@slac.stanford.edu>
135
136        * new-exceptions/bspsupport/ppc_exc_asm_macros.h: Added
137        a test to TEST_LOCK_crit so that a context switch is
138        always prevented if MSR_CE is not set in the interrupt mask.
139        (Support mode where the user wants to leave MSR_CE always enabled
140        but abstains from calling OS primitives from the exception
141        handler.)
142
1432008-07-16      Till Straumann <strauman@slac.stanford.edu>
144
145        * shared/include/powerpc-utility.h: Added
146        GET_INTERRUPT_MASK macro.
147
1482008-07-16      Joel Sherrill <joel.sherrill@oarcorp.com>
149
150        * mpc6xx/clock/c_clock.c: Add fast idle.
151
1522008-07-14      Sebastian Huber <sebastian.huber@embedded-brains.de>
153
154        * configure.ac: Support for MPC55XX.  Changed comment format to
155        Doxygen.
156
157        * mpc55xx/dspi/dspi.c, mpc55xx/edma/edma.c, mpc55xx/esci/esci.c,

162        mpc55xx/misc/flash.S, mpc55xx/misc/fmpll.S: New BSP.
163
164        * mpc83xx/i2c/mpc83xx_i2cdrv.c,
165        mpc83xx/network/tsec.c, mpc83xx/spi/mpc83xx_spidrv.c,

167
168        * shared/include/powerpc-utility.h: Exchanged ASM and non ASM code
169        sections.
170
171        * rtems/powerpc/powerpc.h, shared/src/cache.c, shared/src/cache_.h:
172        New defines PPC_NO_CACHE_ALIGNMENT and PPC_NO_CACHE_ALIGNMENT_POWER for
173        CPUs with no cache.  Provide default implementations for all cache
174        functions.
175
176        * mpc83xx/include/gtm.h, mpc83xx/gtm/gtm.c: New files.
177
1782008-07-14      Thomas Doerfler <thomas.doerfler@embedded-brains.de>
179
180        * Makefile.am, new-exceptions/raw_exception.c,
181        * new-exceptions/bspsupport/irq.c, ppc403/clock/clock_4xx.c,

184        * shared/include/cpuIdent.c, shared/include/cpuIdent.h,
185        * shared/include/powerpc-utility.h:
186        Added support for PPC405EX (contributed by Michael Hamel)
187       
1882008-07-11      Sebastian Huber <sebastian.huber@embedded-brains.de>
189
190        * Makefile.am: Install powerpc-utility.h.
191
192        * shared/include/cpuIdent.h, shared/include/cpuIdent.c: Added e200 and
193        e300 features.
194
195        * new-exceptions/cpu.c: Removed PR288 bugfix check.
196
197        * new-exceptions/e500_raw_exc_init.c: Added initialization for e200.
198        Set IVPR register for e200 and e500 to ppc_exc_vector_base.
199
200        * new-exceptions/raw_exception.c, new-exceptions/raw_exception.h: Added
201        vector categories for e200 and e300 cores.  Added global variable
202        ppc_exc_vector_base for CPUs with IVPR register.
203
204        * new-exceptions/bspsupport/ppc_exc.S,
205        * new-exceptions/bspsupport/ppc_exc_asm_macros.h,
206        * new-exceptions/bspsupport/ppc_exc_bspsupp.h,
207        * new-exceptions/bspsupport/ppc_exc_hdl.c,
208        * new-exceptions/bspsupport/vectors.h,
209        * new-exceptions/bspsupport/vectors_init.c:
210        Conistent code layout in most assember code sections and usage of
211        defines for registers.  Usage of standard header files to avoid
212        multiple definitions.
213       
214        Optimized exception code: Removed many branches and exploit branch
215        prediction for asynchronous exceptions, moved common wrap code into
216        WRAP macro to eliminate branch, static initialization of the handler
217        table with a default handler to eliminate the test if a handler is
218        present.  Register CR6 is no more cleared because the exeption handler
219        functions are not variadic.
220       
221        New method to switch to the interrupt stack. It will be tested if the
222        exception stack pointer is already inside the interrupt stack area.  It
223        is no more necessary to disable interrupts.  The SPRG1 and SPRG2 are
224        used to store the initial interrupt stack pointer and the interrupt
225        stack memory area start.
226
227        Removed variable ppc_exc_msr_irq_mask and use general interrupt disable
228        mask from SPRG0 instead.
229
230        New initialization routine ppc_exc_initialize() for bsp_start().  It
231        takes the interrupt disable mask, interrupt stack start and size as
232        parameters.
233
234        Added packed prologues for CPUs with IVPR and IVOR registers to save
235        memory space.
236
237        Reverted ppc_exc_crit_always_enabled change from yesterday.
238
239        WARNING: Tests with critical interrupt exceptions crash the system at
240        least on MPC8313ERDB and MPC8349EAMDS.  There may be somewhere a
241        serious bug with the new code.
242
2432008-07-10      Till Straumann <strauman@slac.stanford.edu>
244
245        * mpc6xx/mmu/pte121.c: use general "memory" clobber
246        rather than memory input operand in inline assembly
247        ("m" doesn't do what the manual says; see discussion
248        on gcc mailing list around 2008/3/30)
249
2502008-07-10      Till Straumann <strauman@slac.stanford.edu>
251
252        * ChangeLog, mpc8xx/clock/clock.c, ppc403/clock/clock.c,
253        ppc403/irq/ictrl.h, rtems/powerpc/powerpc.h:
254        Removed all macro definitions which depended on
255        the compiler defining a PPC CPU-model dependent
256        symbol from files in cpukit.
257        Macros which were not used by cpukit have been
258        moved to libcpu/powerpc/rtems/powerpc/powerpc.h.
259
2602008-07-10      Till Straumann <strauman@slac.stanford.edu>
261
262        * new-exceptions/bspsupport/README,
263        new-exceptions/bspsupport/ppc_exc.S,
264        new-exceptions/bspsupport/ppc_exc_asm_macros.h,
265        new-exceptions/bspsupport/ppc_exc_bspsupp.h,
266        new-exceptions/bspsupport/ppc_exc_hdl.c,
267        new-exceptions/bspsupport/vectors_init.c:
268        Fixed and enabled stack-switching algorithm which figures out
269        if we already run on the ISR stack rather than relying on the
270        _ISR_Nest_level.
271        Added 'ppc_exc_crit_always_enabled' variable which defines
272        the semantics of critical interrupts.
273        Let asynchronous machine-check handling never call the dispatcher.
274        We don't want to disable MSR_ME ever (to avoid checkstops)
275        and hence asynchronous MEs must not use OS services anyways.
276
2772008-07-09      Sebastian Huber <sebastian.huber@embedded-brains.de>
278
279        * shared/include/powerpc-utility.h: Includes standard header files,
280        provides common assembler macros and inline functions for low-level
281        code.
282
2832008-05-23      Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>
284
285        * mpc83xx/network/tsec.c:
286        disabled debugging output, reduced rx interrupt coalescing
287
2882008-05-22      Till Straumann <strauman@slac.stanford.edu>
289
290        * ppc403/tty_drv/tty_drv.c, ppc403/console/console405.c:
291        ../ictrl/ictrl.h has gone; include ../irq/ictrl.h
292
2932008-05-16      Joel Sherrill <joel.sherrill@OARcorp.com>
294
295        * mpc83xx/include/mpc83xx.h: or is not a good name for any name in
296        C/C++. See iso646.h for the reason.
297
2982008-05-15      Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>
299
300        * mpc83xx/i2c/mpc83xx_i2cdrv.c:

302
3032008-05-15      Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>
304
305        * mpc83xx/network/tsec.c, mpc83xx/include/mpc83xx.h:
306        added support for RGMII interface and different board
307
3082008-05-15      Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>
309
310        * mpc83xx/i2c/mpc83xx_i2cdrv.c, mpc83xx/i2c/mpc83xx_i2cdrv.h,
311        * mpc83xx/spi/mpc83xx_spidrv.c, mpc83xx/spi/mpc83xx_spidrv.h:
312        added base frequency into softc structure
313
3142008-05-14      Till Straumann <strauman@slac.stanford.edu>
315
316        * new-exceptions/bspsupport/ppc_exc_bspsupp.h: added
317        comment about the semantics of the return value of
318        ppc_exc_handler_t.
319
3202008-05-14      Till Straumann <strauman@slac.stanford.edu>
321
322        * new-exceptions/bspsupport/irq.c: moved malloc/free
323        outside of irq-protected critical section.
324
3252008-04-24      Joel Sherrill <joel.sherrill@OARcorp.com>
326
327        * mpc8260/console-generic/console-generic.c,
328        mpc8xx/console-generic/console-generic.c: Remove all references to
329        console_reserve_resources and termios_reserve_resources.
330
3312008-04-24      Nigel Spon <nigel@adi.co.nz>
332
333        * ppc403/console/console.c: Correct include path.
334
3352008-04-23      Joel Sherrill <joel.sherrill@OARcorp.com>
336
337        * mpc5xx/console-generic/console-generic.c, mpc5xx/include/console.h,
338        mpc8260/console-generic/console-generic.c, mpc8260/include/console.h,
339        mpc8xx/console-generic/console-generic.c, mpc8xx/include/console.h:
340        Remove all references to console_reserve_resources and
341        termios_reserve_resources.
342
3432008-04-07      Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>
344
345        * README:
346        removed reference to outdated "old-exception-handling" PPC support
347
3482008-03-20      Till Straumann <strauman@slac.stanford.edu>
349
350        * new-exceptions/bspsupport/irq.c: don't disable irqs
351        at the interrupt controller (PIC) during initialization -- this
352        caused problems where some BSPs's BSP_disable_irq_at_pic() routine
353        did not ignore IRQ lines associated with cascaded PICs.
354        Rely on the BSP (BSP_setup_the_pic()) to provide a good
355        initial setup.
356
3572008-03-13      Till Straumann <strauman@slac.stanford.edu>
358
359        * new-exceptions/bspsupport/ppc_exc_asm_macros.h,
360        new-exceptions/bspsupport/ppc_exc.S,
361        new-exceptions/bspsupport/README,
362        new-exceptions/bspsupport/ppc_exc_hdl.c:
363        Thomas Doerfler clarified (thanks!) that raising an
364        exception and executing the 1st instruction is not
365        an atomical operation. I added a fix to the code that
366        checks if a lower-priority interrupt is under way:
367        we now not only test if the 'lock' variable was set
368        but also check if the interrupted PC points to the
369        'write lock' instruction.
370        Added more comments and updated README.
371
3722008-03-11      Till Straumann <strauman@slac.stanford.edu>
373
374        * new-exceptions/bspsupport/ppc_exc_asm_macros.h: bugfix;
375        need to crand not cror when testing lower priority locks
376        during machine-check handling.
377
3782008-03-05      Till Straumann <strauman@slac.stanford.edu>
379
380        * new-exceptions/bspsupport/ppc_exc_asm_macros.h: bugfix;
381        need to andc with irq mask when disabling interrupts.

537        Changed implementation of <cpu>_vector_is_valid() from 'case'
538        statements to table lookup.
539        Replaced 'ASM_VECTORS_CRITICAL' by a variable
540        'bsp_raw_vector_is_405_critical' which is set at run-time.
541        Removed PPC_MSR_EXC_BITS. The exception handling code
542        (libbsp/shared/vectors/vectors.S and ../irq/irq_asm.S) now
543        has a run-time check for these bits.

550        support for e500 CPU. Most stuff is borrowed from mpc6xx.
551
5522007-12-05      Till Straumann <strauman@slac.stanford.edu>
553
554        * rtems/powerpc/powerpc.h: added a #ifdef __ppc_generic
555        branch. The goal is eventually to make this the starting
556        point for cleanup (remove as many branches as possible;
557        replace by run-time tests if necessary).

5592007-12-05      Joel Sherrill <joel.sherrill@OARcorp.com>

569
570        * new-exceptions/raw_exception.c, new-exceptions/raw_exception.h:
571        Added typedef for exception classes (classic, critical, ...
572        synchronous / asynchronous). ppc_vector_is_valid() now returns
573        the appropriate class.
574
5752007-12-05      Till Straumann <strauman@slac.stanford.edu>
576
577        * new-exceptions/raw_exception.c: made all <cpu>_vector_is_valid()

579
5802007-12-05      Till Straumann <strauman@slac.stanford.edu>
581
582        * new-exceptions/raw_exception.c, new-exceptions/raw_exception.h:
583        Qualified all exception vector symbols that are only defined
584        #ifdef <cpu_flavor> with <cpu_flavor> in the symbol name.
585        If the special flavor __ppc_generic is effective the ALL
586        vector symbols are available and ppc_vector_is_valid() works
587        for all supported CPUs (run-time check).
588        This is work towards a #ifdef <cpu_flavor> free libcpu and
589        exception framework.

593        * mpc5xx/console-generic/console-generic.c, mpc8260/timer/timer.c,
594        new-exceptions/cpu.c, old-exceptions/cpu.c: Move interrupt_stack_size
595        field from CPU Table to Configuration Table. Eliminate CPU Table from
596        all ports. Delete references to CPU Table in all forms.

602       
6032007-12-03      Joel Sherrill <joel.sherrill@OARcorp.com>
604
605        * mpc5xx/console-generic/console-generic.c: Moved most of the remaining
606        CPU Table fields to the Configuration Table. This included
607        pretasking_hook, predriver_hook, postdriver_hook, idle_task,
608        do_zero_of_workspace, extra_mpci_receive_server_stack,
609        stack_allocate_hook, and stack_free_hook. As a side-effect of this
610        effort some multiprocessing code was made conditional and some style
611        clean up occurred.
612
6132007-12-03      Joel Sherrill <joel.sherrill@oarcorp.com>

618
619        * new-exceptions/raw_exception.c, new-exceptions/raw_exception.h,
620        old-exception/cpu.c: define bsp_exceptions_in_RAM variable.
621        This is probably only used by the simulator (were else
622        can you install something to ROM ??).
623
6242007-11-30      Till Straumann <strauman@slac.stanford.edu>
625
626        * mpc6xx/mmu/bat.c, mpc6xx/mmu/pte121.c: use new
627        feature-checks from cpuIdent.h rather than filtering
628        CPU types when checking for availability of high BATs
629        and an MMU with hardware page-table lookup.
630
6312007-11-30      Till Straumann <strauman@slac.stanford.edu>
632
633        * mpc6xx/clock/c_clock.c, mpc6xx/clock/c_clock.h:
634        added support for bookE/ppc405 style CPUs where the
635        decrementer works slightly differently.
636
6372007-11-29      Till Straumann <strauman@slac.stanford.edu>
638
639        * mpc6xx/exceptions/raw_exception.c,

641        uses generic version in new-exceptions.
642

644
645        * shared/include/cpuIdent.h, shared/include/cpuIdent.c:
646        Added a simple 'feature check' facility. Code should
647        not check for a particular CPU type if possible but
648        check the respective feature bit (e.g., 'has_altivec').
649        This makes it much less cumbersome to add more CPU
650        types in the future.

17812001-11-21      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
1782
1783        * configure.ac: Remove ppc603e from old_exception_processing.
1784        * configure.ac: Remove mpc750 from new_exception_processing, Remove
1785        mpc604 from new_exception_processing.
1786        * old-exceptions/Makefile.am, new-exceptions/Makefile.am: Preinstall
1787        c_isr.inl (HACK).

1793
17942001-11-14      Till Straumann <strauman@SLAC.Stanford.EDU>
1795
1796        * new_exception_processing/cpu_asm.S: Support double or single
1797        precision context switches.  Note that doing a single precision
1798        context save/restore on a double precision PowerPC machine does not
1799        only result in rounding errors but also screws up the FPSCR
1800        register!

18022001-11-08      Dennis Ehlin (ECS) <Dennis.Ehlin@ecs.ericsson.se>
1803
1804        This modification is part of the submitted modifications necessary
1805        to
1806        support the IBM PPC405 family.  This submission was reviewed by
1807        Thomas Doerfler <Thomas.Doerfler@imd-systems.de> who ensured it did
1808        not negatively impact the ppc403 BSPs.  The submission and tracking
1809        process was captured as PR50.
1810        * ppc403/console/console405.c,
1811        ppc403/tty_drv/Makefile.am, ppc403/tty_drv/tty_drv.c,

1818
18192001-11-07      Joel Sherrill <joel@OARcorp.com>
1820
1821        * configure.ac: Delete the commented out line that said that the
1822        mpc8260 used the old exception processing model.  This line also
1823        appears to have caused ppc603e to miss this test.
1824
18252001-10-29      Joel Sherrill <joel@OARcorp.com>
1826
1827        * mpc8xx/timer/timer.c: Added hack for two macros that are not
1828        defined with the new exception processing model:
1829        rtems_cpu_configuration_get_timer_least_valid()
1830        rtems_cpu_configuration_get_timer_average_overhead() This is
1831        captured as PR57.

1839
1840        * mpc8260/include/mpc8260.h: "or" is a keyword in C++.
1841

1843
1844        * Added mpc8260 directory.

18712001-10-11      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
1872
1873        * configure.ac: New file, generated from configure.in by autoupdate.

1890        rtems_bsp_delay_in_bus_cycles().
1891
18922001-05-24      Tom Armistead <tom_armistead@phx.mcd.mot.com>
1893
1894        * mpc6xx/timer/timer.c: Added include of bsp.h and removed external
1895        declaration of BSP_Convert_decrementer() to  correct unresolved
1896        reference to this routine.
1897
18982001-05-24      Eric Valette <valette@crf.canon.fr>
1899
1900        * mpc8xx/console-generic/console-generic.c: Bug found by Yacine
1901        <elkolli@crf.canon.fr> where the initialization or irq data
1902        structure was incomplete in case a SMC channel was used first and
1903        later a SCC one.
1904
19052001-05-17      Joel Sherrill <joel@OARcorp.com>
1906
1907        * mpc6xx/exceptions/raw_exception.c, pc6xx/mmu/pte121.c: Modified
1908        slightly to reflect recent PowerPC re-organization and avoid
1909        warnings.
1910
19112001-05-15      Till Straumann <strauman@slac.stanford.edu>
1912
1913        * mpc6xx/mmu/pte121.c, mpc6xx/mmu/pte121.h: New files. Missed in
1914        merge of PR213.
1915
19162001-05-14      Till Straumann <strauman@slac.stanford.edu>
1917
1918        * rtems/powerpc/registers.h, rtems/score/ppc.h: Per PR213, add  the
1919        following: - support for the MPC74000 (AKA G4); there is no AltiVec
1920        support yet, however. - the cache flushing assembly code uses
1921        hardware-flush on the G4. Also, a couple of hardcoded numerical
1922        values were replaced by more readable symbolic constants. - extended
1923        interrupt-disabled code section so enclose the entire cache
1924        flush/invalidate procedure (as recommended by the book). This is not
1925        (latency) critical as it is only used by init code but prevents
1926        possible corruption. - Trivial page table support as been added.
1927        (1:1 effective-virtual-physical address mapping which is only useful
1928        only on CPUs which feature hardware TLB replacement, e.g. >604.
1929        This allows for write-protecting memory regions, e.g. text/ro-data
1930        which makes catching corruptors a lot easier. It also frees one
1931        DBAT/IBAT and gives more flexibility for setting up address maps :
1932        -) - setdbat() allows changing BAT0 also (since the BSP may use a
1933        page table, BAT0 could be available...). - asm_setdbatX() violated
1934        the SVR ABI by using r20 as a scratch register; changed for r0 -
1935        according to the book, a context synchronizing instruction is
1936        necessary prior to and after changing a DBAT -> isync added
1937        * new-exceptions/cpu.c: Per PR211 fix saving/restoring floating
1938        point context.  The fpsave and fprestore routines are only used in a
1939        executing context which _is_ fp and hence has the FPU enabled. The
1940        current behavior required the FPU always to be on which is very
1941        dangerous if lazy context switching is used.   [Joel Note: Some
1942        ports explicitly enabled the FPU in the FP save and restore routines
1943        to avoid this.] The patch also makes sure (on powerpc only) that the
1944        FPU is disabled for integer tasks. Note that this is crucial if
1945        deferred fp context switching is used. Otherwise, fp context
1946        corruption may go undetected! Also note that even tasks which merely
1947        push/pop FP registers to/from the stack without modifying them still
1948        MUST be FP tasks - otherwise (if lazy FP context switching is used),
1949        FP register corruption (of other, FP, tasks may occur)! Furthermore,
1950        (on PPC) by default, lazy FP context save/restore is _disabled_.
1951        * shared/include/io.h: Per PR215 address the following issues: -
1952        _IO_BASE, _ISA_MEM_BASE and PCI_DRAM_OFFSET are no longer defined by
1953        libcpu (powerpc/shared/include/io.h) but by the BSP (who is the only
1954        one to know the values) - the affected BSP (shared/motorola) headers
1955        have been fixed in a separate "libbsp/powerpc/shared" patch. - the
1956        DEC 21140 driver (libchip/network/dec21140.c) has been fixed to use
1957        PCI_DRAM_OFFSET instead of PREP_PCI_DRAM_OFFSET. and PCI_MEM_BASE
1958        instead of PREP_ISA_MEM_BASE. PCI_MEM_BASE is to be defined by the
1959        BSP who is using this driver. - the DEC driver also has been fixed
1960        to use the newer rtems_bsp_delay_in_bus_cycles() instead of the
1961        obsolete delay_in_bus_cycles().
1962
19632001-05-14      Joel Sherrill <joel@OARcorp.com>
1964
1965        * shared/include/cpuIdent.c: Account for duplicate numbers.
1966
19672001-04-17      Joel Sherrill <joel@OARcorp.com>
1968
1969        * shared/include/cpu.h: Added ifndef ASM.
1970
19712001-04-03      Joel Sherrill <joel@OARcorp.com>
1972
1973        * Closed PR57.  The hack is OK as it allows a BSP to override or not
1974        at its discretion.
1975        * Per PR94, all rtems/score/CPUtypes.h are named
1976        rtems/score/types.h.
1977        * Per PR94, all rtems/score/CPUtypes.h are named
1978        rtems/score/types.h.
1979        * mpc8xx/timer/timer.c: Removed #warning declaring providing a
1980        default definition for the macros
1981        rtems_cpu_configuration_get_timer_least_valid and
1982        rtems_cpu_configuration_get_timer_average_overhead.
1983        * old-exceptions/rtems/score/cpu.h,
1984        new-exceptions/rtems/score/cpu.h: Account for name change.
1985
19862001-03-30      Eric Valette <valette@crf.canon.fr>
1987
1988        * mpc8xx/vectors/Makefile.am,
1989        mpc8xx/vectors/README, mpc8xx/vectors/align_h.S
1990        mpc8xx/vectors/vectors.S: These files were removed in support of
1991        switching the mpc8xx to the use the "new exception processing
1992        model."
1993        * configure.in, mpc6xx/mmu/bat.h, mpc8xx/Makefile.am,
1994        mpc8xx/clock/clock.c, mpc8xx/console-generic/console-generic.c,
1995        mpc8xx/include/mpc8xx.h, mpc8xx/mmu/mmu.c,
1996        new_exception_processing/cpu.h, shared/include/byteorder.h,
1997        wrapup/Makefile.am: This is conversion of the mpc8xx CPU to the "new
1998        exception processing model."
1999        * mpc8xx/exceptions/Makefile.am,
2000        mpc8xx/exceptions/asm_utils.S, mpc8xx/exceptions/raw_exception.c,
2001        mpc8xx/exceptions/raw_exception.h: New files.
2002
20032001-02-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
2004
2005        * mpc505/ictrl/Makefile.am, mpc6xx/clock/Makefile.am,
2006        mpc6xx/exceptions/Makefile.am, mpc6xx/mmu/Makefile.am,
2007        mpc8xx/include/Makefile.am, new_exception_processing/Makefile.am,
2008        old_exception_processing/Makefile.am, pc403/ictrl/Makefile.am,
2009        shared/include/Makefile.am, shared/src/Makefile.am: Apply *_HEADERS
2010        instead of *H_FILES.
2011
20122001-01-03      Joel Sherrill <joel@OARcorp.com>
2013
2014        * new_exception_processing/cpu.h, old_exception_processing/cpu.c:
2015        old_exception_processing/cpu.h, Added _CPU_Initialize_vectors(). In
2016        particular, spurious vector initialization had to be moved on old
2017        exception processing model.
2018
20192000-11-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
2020
2021        * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
2022
20232000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
2024
2025        * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I
2026        $(RTEMS_TOPdir)/aclocal.
2027
20282000-10-26      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
2029
2030        * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros. Switch to
2031        GNU canonicalization.
2032
20332000-10-20      Joel Sherrill <joel@OARcorp.com>
2034
2035        * mpc8xx/console-generic/console-generic.c: Avoid use of BSP
2036        definitions and rely on the new routine
2037        mbx8xx_console_get_configuration() to get information.  This routine
2038        was formerly incorrectly called
2039        mbx8xx_console_use_maximum_buffer_size(). binding to the exception
2040        code.
2041        * configure.in, Makefile.am: Explicitly specify whether an
2042        RTEMS_CPU_MODEL is using old or new exception processing.  This is
2043        important because when building multilib, you do not know  the
2044        RTEMS_CPU_MODEL.  So everything built in a multilib'ed RTEMS must be
2045        independent of the exception model and allow for late binding to the
2046        exception code.
2047
20482000-10-18      Sergei Organov <osv@javad.ru>
2049
2050        * Added full support for MPC505.
2051        * configure.in, mpc505/Makefile.am: Modified to reflect ictrl
2052        addition.
2053        * old_exception_processing/Makefile.am: Account for ppc_offs.h.
2054        * old_exception_processing/cpu_asm.S: Offsets moved to ppc_offs.h.
2055        * mpc505/timer/timer.c: Use <rtems.h>, not "rtems.h".
2056        * mpc505/vectors/vectors.S: Now use constants for exception numbers.
2057        * mpc505/ictrl: New directory.
2058        * old_exception_processing/ppc_offs.h: New file.
2059        * old_exception_processing/cpu.h: Make Nest and Disable levels
2060        volatile.
2061        * mpc505/vectors/Makefile.am: alignment exception handler now
2062        included.
2063        * mpc505/ictrl/Makefile.am,
2064        mpc505/ictrl/ictrl.c, mpc505/ictrl/ictrl.h: New files.
2065
20662000-10-18      Joel Sherrill <joel@OARcorp.com>
2067
2068        * mpc8xx/console-generic/console-generic.c: Removed include of
2069        <bsp.h> by adding BSP dependent routine
2070        mbx8xx_console_use_maximum_buffer_size() which can be hard coded or
2071        check non-volatile memory for configuration.
2072        * mpc8xx/console-generic/console-generic.c: Removed warnings.
2073        * mpc6xx/clock/c_clock.h: Removed commented out reference to
2074        <bsp.h>.
2075        * mpc6xx/timer/timer.c, mpc6xx/timer/timer.c: Ditto.
2076        * mpc6xx/clock/c_clock.c, mpc6xx/clock/c_clock.h: Removed use of
2077        bsp.h and replaced it with use of proper interfaces or explicit
2078        externs of required functions and data.
2079
20802000-09-04      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

2109        * mpc8xx/console-generic/console-generic.c: The printk/printf did
2110        not work when loaded by EPPCBUG. They did work when loaded with the
2111        BDM debugger.  I suspected EPPBUG  made some nasty things like
2112        patching Communication processor microcode...  Anyway, the attached
2113        patch: 1) Enables to have printk nearly immediately after boot, 2)
2114        Make printf work automagically (I do not know why except I make a
2115        different initialization for printk that should be overwritten by
2116        console init later ?) I let the default to be using EPPCBUG embedded
2117        firmware to boot and  using this printk early enabler code
2118        (LOADED_BY_EPPCBUG and  EARLY_CONSOLE) are on.
