4
52008-06-02      Joel Sherrill <joel.sherrill@oarcorp.com>

7        * shared/startup/panic.c: Convention calls for leading underscore on
8        private RTEMS variables.
9
102008-05-23      Till Straumann <strauman@slac.stanford.edu>
11
12        * shared/startup/pretaskinghook.c: removed declaration
13        of BSP_vme_config() (which is already declared in
14        <bsp/VME.h>. Removed test for NULL-ness of BSP_vme_config;
15        gcc doesn't seem to understand that the linker may
16        define this to be NULL... Silences a compiler warning
17        (and users can always provide an empty routine).
18
192008-05-22      Till Straumann <strauman@slac.stanford.edu>
20
21        * shared/startup/linkcmds, shared/startup/zerobss.c:
22        introduced '__bss_end'; assuming that __rtems_end
23        coincides with the end of .bss for the purpose of
24        zeroing .bss is very dangerous.
25
262008-05-22      Joel Sherrill <joel.sherrill@OARcorp.com>
27
28        * shared/console/console.c: Fix typo.
29
302008-05-22      Joel Sherrill <joel.sherrill@oarcorp.com>
31
32        * shared/console/console.c: Remove explicit switch and call
33        termios_baud_to_number().
34
352008-05-15      Joel Sherrill <joel.sherrill@OARcorp.com>
36
37        * shared/startup/pretaskinghook.c: Add capability for bootcard.c BSP
38        Initialization Framework to ask the BSP where it has memory for the
39        RTEMS Workspace and C Program Heap. These collectively are referred
40        to as work area. If the BSP supports this, then it does not have to
41        include code to split the available memory between the two areas.
42        This reduces the amount of code in the BSP specific bspstart.c file.
43        Additionally, the shared framework can initialize the C Library, call
44        rtems_debug_enable(), and dirty the work area memory. Until most/all
45        BSPs support this new capability, if the BSP supports this, it should
46        call RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION from its configure.ac.
47        When the transition is complete, this autoconf macro can be removed.
48
492008-05-12      Joel Sherrill <joel.sherrill@OARcorp.com>
50
51        * shared/startup/bspstart.c: Refactored and renamed initialization
52        routines to rtems_initialize_data_structures,
53        rtems_initialize_before_drivers, rtems_initialize_device_drivers, and
54        rtems_initialize_start_multitasking. This opened the sequence up so
55        that bootcard() could provide a more robust and flexible framework
56        which is easier to explain and understand. This also lays the
57        groundwork for sharing the division of available memory between the
58        RTEMS workspace and heap and the C library initialization across all
59        BSPs.
60
612008-03-21      Till Straumann <strauman@slac.stanford.edu>
62
63        * shared/console/uart.c: In IRQ driven mode also
64        keep reading chars while they are available (fifo
65        could be enabled).
66
672008-03-19      Till Straumann <strauman@slac.stanford.edu>
68
69        * shared/console/console.c, shared/console/uart.c,
70        shared/console/uart.h: added support for task-driven
71        console.
72
732008-03-19      Till Straumann <strauman@slac.stanford.edu>
74
75        * shared/startup/pretaskinghook.c: install pointer
76        to rtems_malloc_sbrk_helpers_table. This (and derived)
77        BSPs rely on sbrk delivering even the first/initial
78        chunk of memory.
79
802008-03-03      Joel Sherrill <joel.sherrill@OARcorp.com>
81
82        * shared/startup/linkcmds: Add wildcard to gcc_except_table section so
83        programs compiled with gcc 4.3.x can link.
84
852008-02-19      Ralf Corsépius <ralf.corsepius@rtems.org>
86
87        * gen405: Remove (Abandoned).
88        * helas403: Remove (Abandoned).
89        * acinclude: Regenerate.
90
912007-12-14      Joel Sherrill <joel.sherrill@oarcorp.com>
92
93        * acinclude.m4, gen5200/irq/irq.c, gen5200/startup/bspclean.c: Add
94        mvme3100.
95
962007-12-11      Joel Sherrill <joel.sherrill@OARcorp.com>
97
98        * shared/startup/bspstart.c, shared/startup/pretaskinghook.c: Eliminate
99        copies of the Configuration Table. Use the RTEMS provided accessor
100        macros to obtain configuration fields.
101
1022007-12-10      Till Straumann <strauman@slac.stanford.edu>
103
104        * Makefile.am, start/preload.S: moved preload.S
105        to ../shared/start.
106
1072007-12-10      Till Straumann <strauman@slac.stanford.edu>
108
109        * shared/irq/irq_asm.S, shared/vectors/vectors.h:
110        renamed ASM_BOOKE_PIT_VECTOR to ASM_BOOKE_DEC_VECTOR
111        to be closer to 'official' nomenclature.
112
1132007-12-10      Till Straumann <strauman@slac.stanford.edu>
114
115        * shared/openpic/openpic.c: fixed wrong register
116        address in openpic_gettimer().
117
1182007-12-10      Till Straumann <strauman@slac.stanford.edu>
119
120        * shared/motorola/vpd.c, shared/motorola/vpd.h:
121        added code (originally developed for 'beatnik')
122        to read MotLoad VPD data from i2c eeprom.
123
1242007-12-10      Till Straumann <strauman@slac.stanford.edu>
125
126        * shared/vectors/README.deprecated, shared/irq/README.deprecated:
127        added READMEs stating that certain files should not be
128        copy/paste/modified when creating new BSPs. New BSPs
129        are encouraged to use the new library under
130        libcpu/powerpc/new-exceptions/bspsupport.
131
1322007-12-10      Till Straumann <strauman@slac.stanford.edu>
133       
134        * shared/vectors/vectors_entry.S, motorola_powerpc/bsp_specs,
135        shared/start/vectors_entry.S: moved vectors_entry.S to
136        'start' subdir and made a start file rather than
137        element of vectors.rel (it should always be linked but
138        won't if it is the sole member of vectors.rel).
139
1402007-12-08      Till Straumann <strauman@slac.stanford.edu>
141
142        * shared/vme/vme_universe.c: fixed wrong initialization
143        routine when using Tsi148 driver.
144
1452007-12-08      Till Straumann <strauman@slac.stanford.edu>
146
147        * Makefile.am: merged shared/vme/vme_universe.c and
148        shared/vme/vme_universe_dma.c into one file.
149        Added support for Tsi148 driver (DMA).
150
1512007-12-08      Till Straumann <strauman@slac.stanford.edu>
152
153        * shared/vme/VMEConfig.h, shared/vme/vme_universe.c:
154        added support for Tsi148 bridge; BSP can define which
155        bridge driver to use from VMEConfig.h.
156        Added 'err' macro parameter to BSP_VME_INSTALL_IRQ_MGR(err)
157        macro so that an error status can be passed back.
158
1592007-12-08      Till Straumann <strauman@slac.stanford.edu>
160
161        * irq_supp.h: was moved from shared/irq to
162        libcpu/powerpc/new-exceptions/bspsupport.
163
1642007-12-08      Till Straumann <strauman@slac.stanford.edu>
165
166        * ep1a/irq/irq.c, gen5200/irq/irq.c, gen83xx/irq/irq_init.c,
167        mbx8xx/irq/irq.c, mpc8260ads/irq/irq.c, mvme5500/irq/irq.c,
168        psim/irq/no_pic.c, score603e/irq/irq.c, shared/irq/irq_supp.h,
169        shared/irq/openpic_i8259_irq.c, virtex/irq/irq_init.c:
170        let C_dispatch_irq_handler() return zero to indicate to
171        low-level exception handling code that the exception
172        was handled (not used yet).
173
1742007-12-08      Till Straumann <strauman@slac.stanford.edu>
175
176        *shared/irq/irq_supp.h: removed cpp test for
177        BSP_SHARED_HANDLER_SUPPORT; BSPs using irq_supp.h
178        *must* implement shared handlers.
179
1802007-12-06      Till Straumann <strauman@slac.stanford.edu>
181
182        * shared/openpic/openpic.c, shared/openpic/openpic.h:
183        added routines to set timer period and interupt mask
184        and to read current count.
185
1862007-12-06      Till Straumann <strauman@slac.stanford.edu>
187
188        * virtex/irq/irq_init.c: use new ASM_xxx_VECTOR names.
189
1902007-12-06      Till Straumann <strauman@slac.stanford.edu>
191
192        * shared/vectors/vectors_init.c: replaced
193        switch ( current_ppc_cpu ) { } check by feature check.
194
1952007-12-06      Till Straumann <strauman@slac.stanford.edu>
196
197        * shared/irq/irq_asm.S, shared/vectors/vectors.S:
198        Replaced use of hardcoded PPC_EXC_MSR_BITS by a
199        run-time method to determine these bits (use settings
200        effective before exception occurred).
201        Replaced use of hardcoded ASM_VECTORS_CRITICAL by
202        'bsp_raw_vector_is_405_critical' variable.
203
2042007-12-05      Till Straumann <strauman@slac.stanford.edu>
205
206        * shared/irq/irq_supp.h: removed stray '*/'. Removed
207        inclusion of <stdlib.h> which is unnecessary and broke
208        if_dc in an obscure way (due to malloc/free redefinition
209        in the networking code).
210
2112007-12-05      Till Straumann <strauman@slac.stanford.edu>
212
213        * shared/irq/irq_asm.S, shared/vectors/vectors.S,
214        shared/vectors/vectors.h, shared/vectors/vectors_init.c:
215        Converted exception vector names to new ones
216        (qualified by <cpu_type> if non-std ppc exceptions).
217
218
2192007-12-04      Till Straumann <strauman@slac.stanford.edu>
220
221        * shared/startup/bspstart.c: export BSP_commandline_string
222        variable.
223
2242007-12-04      Till Straumann <strauman@slac.stanford.edu>
225
226        * shared/flash/flash.c: added lazy init of driver
227        from BSP_flashWriteFile().
228
2292007-12-04      Joel Sherrill <joel.sherrill@OARcorp.com>
230
231        * shared/startup/bspstart.c: Move interrupt_stack_size field from CPU
232        Table to Configuration Table. Eliminate CPU Table from all ports.
233        Delete references to CPU Table in all forms.
234
2352007-12-03      Joel Sherrill <joel.sherrill@oarcorp.com>
236
237        * shared/irq/irq.c: Spacing.
238
2392007-12-03      Joel Sherrill <joel.sherrill@OARcorp.com>
240
241        * shared/startup/bspstart.c: Moved most of the remaining CPU Table
242        fields to the Configuration Table. This included pretasking_hook,
243        predriver_hook, postdriver_hook, idle_task, do_zero_of_workspace,
244        extra_mpci_receive_server_stack, stack_allocate_hook, and
245        stack_free_hook. As a side-effect of this effort some multiprocessing
246        code was made conditional and some style clean up occurred.
247
2482007-12-03      Joel Sherrill <joel.sherrill@oarcorp.com>
249
250        * shared/irq/irq.c, shared/irq/irq_supp.h: Correct conditionals and
251        includes.
252
2532007-12-02      Till Straumann <strauman@slac.stanford.edu>
254
255        * shared/irq/i8259.c, shared/irq/irq.h, shared/irq/irq_supp.h,
256        shared/irq/openpic_i8259_irq.c: BSP_disable_irq_at_pic(),
257        openpic_disable_irq(), BSP_irq_disable_at_i8259s() now return
258        0/1 if irq was disabled/enabled prior to disabling.
259        irq_supp.h now exports a inline helper routine for scanning
260        a list of shared handlers; to be used by PIC drivers.
261
2622007-12-02      Till Straumann <strauman@slac.stanford.edu>
263
264        * shared/openpic/openpic.c shared/openpic/openpic.h,
265        shared/irq/irq_init.c: added more parameters to
266        openpic_init() so that more details of the configuration
267        can be overridden/set from the BSP. Moved setup of
268        the EPIC-specific EOI delay from BSP code into openpic_init()
269        using the new 'epic_freq' parameter.
270
2712007-12-02      Till Straumann <strauman@slac.stanford.edu>
272        * shared/openpic/openpic.c, shared/openpic/openpic.h:
273        - eliminated conditional compilation (#ifdef mpc8240)
274          The difference in register-layout between the EPIC
275          and the std. openPIC is handled by an offset parameter
276          which can be set at run-time (initialization) with
277          a new routine 'openpic_set_src_offset()'.
278        - allow BSP to define symbol BSP_OPEN_PIC_BIG_ENDIAN
279          which builds the driver for big-endian register access
280          (mpc8540).
281        - openpic_disable_irq() now returns the old state so
282          that it can be restored later.
283
2842007-12-01      Till Straumann <strauman@slac.stanford.edu>
285
286        * shared/irq/openpic_i8259_irq.c:
287        - conditionally define 'irq_mask_or_tbl' only if
288          BSP_PCI_ISA_BRIDGE_IRQ is defined.
289        - use _ISR_Get_level() / _ISR_Set_level() for re-enabling
290          interrupts rather than messing with MSR directly;
291          these macros:
292            o implement compiler memory barrier
293                o will handle multiple levels (e500 'critical' interrupts)
294                  if they are ever supported.
295        - decrementer irqs are also shareable - added list traversal.
296
2972007-12-01      Till Straumann <strauman@slac.stanford.edu>
298
299        * shared/irq/irq_supp.h: Make sure BSP_SHARED_HANDLER_SUPPORT
300        is set. The shared irq manager supports shared interrupts
301        (but requires also that the PIC-driver supports them by
302        traversing the list of shared handlers).
303        Declare C_dispatch_irq_handler() which must be defined
304        (like the other routines declared in this header) by the
305        PIC-driver.
306
3072007-12-01      Till Straumann <strauman@slac.stanford.edu>
308
309        * shared/clock/p_clock.c: (run-time) check for e500-cpu
310        and install different ISR for that type of CPU.
311
3122007-12-01      Till Straumann <strauman@slac.stanford.edu>
313
314        * shared/pci/detect_raven_bridge.c: use ifdef mvme2100
315        rather than ifdef mpc824x so that we don't depend on
316        compile-time CPU flavor. Eventually, this should become
317        a run-time check.
318
3192007-12-01      Till Straumann <strauman@slac.stanford.edu>
320
321        * shared/vectors/vectors.h: Give the BSP_Exception_frame
322        struct a name.
323
3242007-12-01      Till Straumann <strauman@slac.stanford.edu>
325
326        * shared/vme/vmeconfig.c: Include <libcpu/bat.h> only
327        if the BSP-specific configuration header (VMEConfig.h)
328        defines BSP_VME_BAT_IDX so that this file can be used
329        on CPUs w/o bats (e500).
330
3312007-11-30      Till Straumann <strauman@slac.stanford.edu>
332
333        * shared/startup/bspstart: removed _Cpu_table.exceptions_in_RAM.
334
3352007-11-30      Till Straumann <strauman@slac.stanford.edu>
336
337        * shared/startup/pretaskinghook.c: Replaced inclusion of
338        <bsp/consoleIo.h> by <rtems/bspIo.> (for printk) and
339        made it conditional on #ifdef SHOW_MORE_INIT_SETTINGS.
340
3412007-11-30      Till Straumann <strauman@slac.stanford.edu>
342
343        * shared/startup/bspstart.c: Removed excess /*, replaced
344        #ifdef checks for mpc8240 by #ifdef mvme2100; eventually
345        there should be run-time checks.
346
3472007-11-30      Till Straumann <strauman@slac.stanford.edu>
348
349        * shared/motorola/motorola.c: removed excess initializer
350        elements.
351
3522007-11-30      Till Straumann <strauman@slac.stanford.edu>
353
354        * shared/irq/irq.h, shared/irq/irq.c, shared/irq/irq_init.c,
355        shared/irq/irq_supp.h (added):
356        Removed 'is_processor_irq()' from irq.c; the BSP routines
357        BSP_enable_irq_at_pic()/BSP_disable_irq_at_pic() are required
358        to ignore processor irqs anyways. Removed
359        all BSP-defined constants from irq.c. This makes irq.c (almost)
360        binary-compatible among BSPs (ultimate goal is making 'shared'
361        a library).
362        Added a header (irq_supp.h) defining the interface between
363        the generic interrupt manager (irq.c) and the routines it
364        requires to be supplied by the BSP (eventually, these
365        should go into rtems/irq.h).
366
3672007-11-30      Till Straumann <strauman@slac.stanford.edu>
368
369        * shared/irq/irq.h, shared/irq/irq_init.c: Removed the definition
370        of ASM_IRQ_VECTOR_BASE; this symbol was only use to
371        initialize the irqBase member of the rtems_irq_global_settings
372        struct. However, irqBase is an rtems_irq_symbolic_name,
373        so using BSP_LOWEST_OFFSET is more appropriate.
374
3752007-11-28      Joel Sherrill <joel.sherrill@OARcorp.com>
376
377        * shared/startup/bspstart.c: Eliminate PowerPC specific elements from
378        the CPU Table. They have been replaced with variables named bsp_XXX
379        as needed.
380
3812007-11-29      Till Straumann <strauman@slac.stanford.edu>
382
383        * Makefile.am, shared/flash, shared/flash/flash.c,
384        shared/flash/flashPgm.h, shared/flash/flashPgmPvt.h,
385        shared/flash/intelFlash.c, shared/flash/spansionFlash.c:
386        Added flash programmer API, implementation and chip drivers
387        for some intel + spansion flash chips (as found on mvme5500,
388        mvme6100 and mvme3100 boards).
389        A more appopriate place would probably be libchip but
390        I don't know if the API is acceptable and if the implementation
391        is generic enough (e.g., no CFI support) so I leave it here
392        for now.
393
3942007-11-26      Joel Sherrill <joel.sherrill@OARcorp.com>
395
396        * shared/console/uart.c: Fix typo and spacing.
397
3982007-11-21      Till Straumann <strauman@slac.stanford.edu>
399
400        * shared/console/uart.c: when draining UART during
401        initialization (wait for possible printk() activity
402        to finish) look at TEMT (fifo, holding-reg and shift-reg)
403        rather than THRE (fifo, holding-reg only). This resolved
404        some scrambled output issues for me.
405
406        Enhanced semantics: if BSP initializes BSPBaseBaud to a negative
407        value then the driver interprets the modulus as a speed value
408        and uses the current setting of the divisor to compute the
409        clock speed (BSPBaseBaud). This is useful if you have a board
410        that you know is initialized e.g., to 9600 but you
411        don't know the clock speed.

1204        This modification is part of the submitted modifications necessary
1205        to
1206        support the IBM PPC405 family.  This submission was reviewed by
1207        Thomas Doerfler <Thomas.Doerfler@imd-systems.de> who ensured it did
1208        not negatively impact the ppc403 BSPs.  The submission and tracking
1209        process was captured as PR50.
1210        * ChangeLog: Removed bogus comment on edit of generated file.
1211        * acinclude.m4: Added gen405 BSP.

1244
1245        * shared/start/start.S: Increased BAT0 mapping of RAM from 64 meg to
1246        256 meg to allow operation on boards with larger RAM sizes.
1247        * shared/vectors/vectors_init.c: Modified to call 'generic' powerpc
1248        vector function (mpc60x_vector_is_valid) instead of MPC750  specific
1249        function to allow operation on boards with CPUs other than the
1250        MPC750.

1262        shared/startup/bspstart.c, shared/vectors/vectors.S,
1263        shared/vectors/vectors.h, shared/vectors/vectors_init.c: Per PR216,
1264        "libbsp/powerpc/shared" BSP has been modified considerably with the
1265        goal to make it more flexible and reusable by other BSPs. The main
1266        strategies were: - eliminate hardcoded base addresses; devices use
1267        offsets and a BSP defined base address. - separate functionality
1268        into different files (e.g. reboot from inch.c to reboot.c) which can
1269        be overridden by a 'derived' BSP. - separate initialization code
1270        into separate files (e.g.  PCI bridge detection/initialization was
1271        separated from the more generic PCI access routines), also to make
1272        it easier for 'derived' BSPs to substitute their own initialization
1273        code. There are also a couple of enhancements and fixes: - IRQ
1274        handling code now has a hook for attaching a VME bridge. - OpenPIC
1275        is now explicitely initialized (polarities, senses). Eliminated the
1276        implicit assumption on the presence of an ISA PIC. - UART and
1277        console driver now supports more than 1 port. The current maximum of
1278        2 can easily be extended by enlarging a table (it would even be
1279        easier if the ISR API was not broken by design). - fixed polled_io.c
1280        so it correctly supports console on COM2 - fixed TLB invalidation
1281        code (start.S). - exception handler prints a stack backtrace. -
1282        added BSP_pciFindDevice() to scan the pci bus for a particular
1283        vendor/device/instance.

1286
1287        * shared/startup/linkcmds: In support of gcc 3.1, added one of more
1288        of the sections .jcr, .rodata*, .data.*, .gnu.linkonce.s2.*,
1289        .gnu.linkonce.sb2.*, and .gnu.linkonce.s.*.  Spacing corrections and
1290        direction of segments to memory regions may also have been
1291        addressed.  This was a sweep across all BSPs.
1292
12932001-04-08      Joel Sherrill <joel@OARcorp.com>
1294
1295        * shared/startup/linkcmds: Per PR170, PR171, and PR172 add .eh_frame

1298
1299        * shared/Makefile.am, shared/console/consoleIo.h,
1300        shared/include/bsp.h: These modifications are part of the conversion
1301        of the mpc8xx CPU to the "new exception processing model."
1302        * configure.in, motorola_powerpc/Makefile.am,
1303        motorola_powerpc/configure.in: These modifications are in support of
1304        switching the mpc8xx to the use the "new exception processing
1305        model."

13112000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
1312

1314        $(RTEMS_TOPdir)/aclocal.
1315
13162000-11-01      Joel Sherrill <joel@OARcorp.com>
1317
1318        * shared/startup/bspstart.c: assoc.h, error.h, libio_.h, libio.h,
1319        and libcsupport.h moved from libc to lib/include/rtems and now must
1320        be referenced as <rtems/XXX.h>.   Header file order was cleaned up
1321        while doing this.
1322
13232000-10-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

13282000-09-29      Charles-Antoine Gauthier <charles.gauthier@nrc.ca>
1329
1330        * shared/startup/linkcmds: Added lines so DWARF debug information
1331        would be available.  Otherwise gdb complains that the offsets for
1332        the debug info are incorrect and doesn't load the files.
1333
13342000-09-05      Joel Sherrill <joel@OARcorp.com>
