4
52008-07-18      Sebastian Huber <sebastian.huber@embedded-brains.de>
6
7        * shared/clock/clock.c: Update due to powerpc-utilty.h changes.
8
92008-07-14      Sebastian Huber <sebastian.huber@embedded-brains.de>
10
11        * mpc55xxevb: New BSP.
12
132008-07-14      Thomas Doefler <Thomas.Doerfler@embedded-brains.de>
14        * haleakala: added new BSP
15
162008-07-11      Sebastian Huber <sebastian.huber@embedded-brains.de>
17
18        * ep1a/startup/bspstart.c, mvme3100/startup/bspstart.c,
19        mvme5500/startup/bspstart.c, psim/startup/bspstart.c,
20        shared/startup/bspstart.c: The usage of SPRG0 as changed.  It is now
21        used to store the interrupt disable mask.  See bootcard.c and
22        ppc_exc_initialize() for default initialization.
23
24        Update to new exception initialization routine ppc_exc_initialize().
25        The exception low level code has changed, see libcpu/powerpc/ChangeLog.
26
27        * gen5200/startup/bspstart.c, mbx8xx/startup/bspstart.c,
28        mpc8260ads/startup/bspstart.c, ss555/startup/bspstart.c,
29        virtex/startup/bspstart.c: The usage of SPRG0 as changed.  It is now
30        used to store the interrupt disable mask.  See bootcard.c for default
31        initialization.
32
332008-07-10      Till Straumann <strauman@slac.stanford.edu>
34
35        * shared/flash/spansionFlash.c: removed "m" memory
36        operands.
37
382008-07-09      Sebastian Huber <sebastian.huber@embedded-brains.de>
39
40        * shared/clock/clock.c: Alternative clock driver.  Uses exception handler
41        directly.  Supports special variants for Book E and e300 cores.  For
42        standard decrementer CPUs the new decrementer value is calculated with
43        reference to a time base so that a time drift is avoided.
44
452008-07-01      Joel Sherrill <joel.sherrill@oarcorp.com>
46
47        * shared/uboot_getenv.c: New file.
48
492008-06-02      Joel Sherrill <joel.sherrill@oarcorp.com>
50
51        * shared/startup/panic.c: Convention calls for leading underscore on
52        private RTEMS variables.
53
542008-05-23      Till Straumann <strauman@slac.stanford.edu>
55
56        * shared/startup/pretaskinghook.c: removed declaration
57        of BSP_vme_config() (which is already declared in
58        <bsp/VME.h>. Removed test for NULL-ness of BSP_vme_config;
59        gcc doesn't seem to understand that the linker may
60        define this to be NULL... Silences a compiler warning
61        (and users can always provide an empty routine).
62
632008-05-22      Till Straumann <strauman@slac.stanford.edu>
64
65        * shared/startup/linkcmds, shared/startup/zerobss.c:
66        introduced '__bss_end'; assuming that __rtems_end
67        coincides with the end of .bss for the purpose of
68        zeroing .bss is very dangerous.
69
702008-05-22      Joel Sherrill <joel.sherrill@OARcorp.com>
71
72        * shared/console/console.c: Fix typo.
73
742008-05-22      Joel Sherrill <joel.sherrill@oarcorp.com>
75
76        * shared/console/console.c: Remove explicit switch and call
77        termios_baud_to_number().
78
792008-05-15      Joel Sherrill <joel.sherrill@OARcorp.com>
80
81        * shared/startup/pretaskinghook.c: Add capability for bootcard.c BSP
82        Initialization Framework to ask the BSP where it has memory for the
83        RTEMS Workspace and C Program Heap. These collectively are referred
84        to as work area. If the BSP supports this, then it does not have to
85        include code to split the available memory between the two areas.
86        This reduces the amount of code in the BSP specific bspstart.c file.
87        Additionally, the shared framework can initialize the C Library, call
88        rtems_debug_enable(), and dirty the work area memory. Until most/all
89        BSPs support this new capability, if the BSP supports this, it should
90        call RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION from its configure.ac.
91        When the transition is complete, this autoconf macro can be removed.
92
932008-05-12      Joel Sherrill <joel.sherrill@OARcorp.com>
94
95        * shared/startup/bspstart.c: Refactored and renamed initialization
96        routines to rtems_initialize_data_structures,
97        rtems_initialize_before_drivers, rtems_initialize_device_drivers, and
98        rtems_initialize_start_multitasking. This opened the sequence up so
99        that bootcard() could provide a more robust and flexible framework
100        which is easier to explain and understand. This also lays the
101        groundwork for sharing the division of available memory between the
102        RTEMS workspace and heap and the C library initialization across all
103        BSPs.
104
1052008-03-21      Till Straumann <strauman@slac.stanford.edu>
106
107        * shared/console/uart.c: In IRQ driven mode also
108        keep reading chars while they are available (fifo
109        could be enabled).
110
1112008-03-19      Till Straumann <strauman@slac.stanford.edu>
112
113        * shared/console/console.c, shared/console/uart.c,
114        shared/console/uart.h: added support for task-driven
115        console.
116
1172008-03-19      Till Straumann <strauman@slac.stanford.edu>
118
119        * shared/startup/pretaskinghook.c: install pointer
120        to rtems_malloc_sbrk_helpers_table. This (and derived)
121        BSPs rely on sbrk delivering even the first/initial
122        chunk of memory.
123
1242008-03-03      Joel Sherrill <joel.sherrill@OARcorp.com>
125
126        * shared/startup/linkcmds: Add wildcard to gcc_except_table section so
127        programs compiled with gcc 4.3.x can link.
128
1292008-02-19      Ralf Corsépius <ralf.corsepius@rtems.org>
130
131        * gen405: Remove (Abandoned).
132        * helas403: Remove (Abandoned).
133        * acinclude: Regenerate.
134
1352007-12-14      Joel Sherrill <joel.sherrill@oarcorp.com>
136
137        * acinclude.m4, gen5200/irq/irq.c, gen5200/startup/bspclean.c: Add
138        mvme3100.
139
1402007-12-11      Joel Sherrill <joel.sherrill@OARcorp.com>
141
142        * shared/startup/bspstart.c, shared/startup/pretaskinghook.c: Eliminate
143        copies of the Configuration Table. Use the RTEMS provided accessor
144        macros to obtain configuration fields.
145
1462007-12-10      Till Straumann <strauman@slac.stanford.edu>
147
148        * Makefile.am, start/preload.S: moved preload.S
149        to ../shared/start.
150
1512007-12-10      Till Straumann <strauman@slac.stanford.edu>
152
153        * shared/irq/irq_asm.S, shared/vectors/vectors.h:
154        renamed ASM_BOOKE_PIT_VECTOR to ASM_BOOKE_DEC_VECTOR
155        to be closer to 'official' nomenclature.
156
1572007-12-10      Till Straumann <strauman@slac.stanford.edu>
158
159        * shared/openpic/openpic.c: fixed wrong register
160        address in openpic_gettimer().
161
1622007-12-10      Till Straumann <strauman@slac.stanford.edu>
163
164        * shared/motorola/vpd.c, shared/motorola/vpd.h:
165        added code (originally developed for 'beatnik')
166        to read MotLoad VPD data from i2c eeprom.
167
1682007-12-10      Till Straumann <strauman@slac.stanford.edu>
169
170        * shared/vectors/README.deprecated, shared/irq/README.deprecated:
171        added READMEs stating that certain files should not be
172        copy/paste/modified when creating new BSPs. New BSPs
173        are encouraged to use the new library under
174        libcpu/powerpc/new-exceptions/bspsupport.
175
1762007-12-10      Till Straumann <strauman@slac.stanford.edu>
177       
178        * shared/vectors/vectors_entry.S, motorola_powerpc/bsp_specs,
179        shared/start/vectors_entry.S: moved vectors_entry.S to
180        'start' subdir and made a start file rather than
181        element of vectors.rel (it should always be linked but
182        won't if it is the sole member of vectors.rel).
183
1842007-12-08      Till Straumann <strauman@slac.stanford.edu>
185
186        * shared/vme/vme_universe.c: fixed wrong initialization
187        routine when using Tsi148 driver.
188
1892007-12-08      Till Straumann <strauman@slac.stanford.edu>
190
191        * Makefile.am: merged shared/vme/vme_universe.c and
192        shared/vme/vme_universe_dma.c into one file.
193        Added support for Tsi148 driver (DMA).
194
1952007-12-08      Till Straumann <strauman@slac.stanford.edu>
196
197        * shared/vme/VMEConfig.h, shared/vme/vme_universe.c:
198        added support for Tsi148 bridge; BSP can define which
199        bridge driver to use from VMEConfig.h.
200        Added 'err' macro parameter to BSP_VME_INSTALL_IRQ_MGR(err)
201        macro so that an error status can be passed back.
202
2032007-12-08      Till Straumann <strauman@slac.stanford.edu>
204
205        * irq_supp.h: was moved from shared/irq to
206        libcpu/powerpc/new-exceptions/bspsupport.
207
2082007-12-08      Till Straumann <strauman@slac.stanford.edu>
209
210        * ep1a/irq/irq.c, gen5200/irq/irq.c, gen83xx/irq/irq_init.c,
211        mbx8xx/irq/irq.c, mpc8260ads/irq/irq.c, mvme5500/irq/irq.c,
212        psim/irq/no_pic.c, score603e/irq/irq.c, shared/irq/irq_supp.h,
213        shared/irq/openpic_i8259_irq.c, virtex/irq/irq_init.c:
214        let C_dispatch_irq_handler() return zero to indicate to
215        low-level exception handling code that the exception
216        was handled (not used yet).
217
2182007-12-08      Till Straumann <strauman@slac.stanford.edu>
219
220        *shared/irq/irq_supp.h: removed cpp test for
221        BSP_SHARED_HANDLER_SUPPORT; BSPs using irq_supp.h
222        *must* implement shared handlers.
223
2242007-12-06      Till Straumann <strauman@slac.stanford.edu>
225
226        * shared/openpic/openpic.c, shared/openpic/openpic.h:
227        added routines to set timer period and interupt mask
228        and to read current count.
229
2302007-12-06      Till Straumann <strauman@slac.stanford.edu>
231
232        * virtex/irq/irq_init.c: use new ASM_xxx_VECTOR names.
233
2342007-12-06      Till Straumann <strauman@slac.stanford.edu>
235
236        * shared/vectors/vectors_init.c: replaced
237        switch ( current_ppc_cpu ) { } check by feature check.
238
2392007-12-06      Till Straumann <strauman@slac.stanford.edu>
240
241        * shared/irq/irq_asm.S, shared/vectors/vectors.S:
242        Replaced use of hardcoded PPC_EXC_MSR_BITS by a
243        run-time method to determine these bits (use settings
244        effective before exception occurred).
245        Replaced use of hardcoded ASM_VECTORS_CRITICAL by
246        'bsp_raw_vector_is_405_critical' variable.
247
2482007-12-05      Till Straumann <strauman@slac.stanford.edu>
249
250        * shared/irq/irq_supp.h: removed stray '*/'. Removed
251        inclusion of <stdlib.h> which is unnecessary and broke
252        if_dc in an obscure way (due to malloc/free redefinition
253        in the networking code).
254
2552007-12-05      Till Straumann <strauman@slac.stanford.edu>
256
257        * shared/irq/irq_asm.S, shared/vectors/vectors.S,
258        shared/vectors/vectors.h, shared/vectors/vectors_init.c:
259        Converted exception vector names to new ones
260        (qualified by <cpu_type> if non-std ppc exceptions).
261
262
2632007-12-04      Till Straumann <strauman@slac.stanford.edu>
264
265        * shared/startup/bspstart.c: export BSP_commandline_string
266        variable.
267
2682007-12-04      Till Straumann <strauman@slac.stanford.edu>
269
270        * shared/flash/flash.c: added lazy init of driver
271        from BSP_flashWriteFile().
272
2732007-12-04      Joel Sherrill <joel.sherrill@OARcorp.com>
274
275        * shared/startup/bspstart.c: Move interrupt_stack_size field from CPU
276        Table to Configuration Table. Eliminate CPU Table from all ports.
277        Delete references to CPU Table in all forms.
278
2792007-12-03      Joel Sherrill <joel.sherrill@oarcorp.com>
280
281        * shared/irq/irq.c: Spacing.
282
2832007-12-03      Joel Sherrill <joel.sherrill@OARcorp.com>
284
285        * shared/startup/bspstart.c: Moved most of the remaining CPU Table
286        fields to the Configuration Table. This included pretasking_hook,
287        predriver_hook, postdriver_hook, idle_task, do_zero_of_workspace,
288        extra_mpci_receive_server_stack, stack_allocate_hook, and
289        stack_free_hook. As a side-effect of this effort some multiprocessing
290        code was made conditional and some style clean up occurred.
291
2922007-12-03      Joel Sherrill <joel.sherrill@oarcorp.com>
293
294        * shared/irq/irq.c, shared/irq/irq_supp.h: Correct conditionals and
295        includes.
296
2972007-12-02      Till Straumann <strauman@slac.stanford.edu>
298
299        * shared/irq/i8259.c, shared/irq/irq.h, shared/irq/irq_supp.h,
300        shared/irq/openpic_i8259_irq.c: BSP_disable_irq_at_pic(),
301        openpic_disable_irq(), BSP_irq_disable_at_i8259s() now return
302        0/1 if irq was disabled/enabled prior to disabling.
303        irq_supp.h now exports a inline helper routine for scanning
304        a list of shared handlers; to be used by PIC drivers.
305
3062007-12-02      Till Straumann <strauman@slac.stanford.edu>
307
308        * shared/openpic/openpic.c shared/openpic/openpic.h,
309        shared/irq/irq_init.c: added more parameters to
310        openpic_init() so that more details of the configuration
311        can be overridden/set from the BSP. Moved setup of
312        the EPIC-specific EOI delay from BSP code into openpic_init()
313        using the new 'epic_freq' parameter.
314
3152007-12-02      Till Straumann <strauman@slac.stanford.edu>
316        * shared/openpic/openpic.c, shared/openpic/openpic.h:
317        - eliminated conditional compilation (#ifdef mpc8240)
318          The difference in register-layout between the EPIC
319          and the std. openPIC is handled by an offset parameter
320          which can be set at run-time (initialization) with
321          a new routine 'openpic_set_src_offset()'.
322        - allow BSP to define symbol BSP_OPEN_PIC_BIG_ENDIAN
323          which builds the driver for big-endian register access
324          (mpc8540).
325        - openpic_disable_irq() now returns the old state so
326          that it can be restored later.
327
3282007-12-01      Till Straumann <strauman@slac.stanford.edu>
329
330        * shared/irq/openpic_i8259_irq.c:
331        - conditionally define 'irq_mask_or_tbl' only if
332          BSP_PCI_ISA_BRIDGE_IRQ is defined.
333        - use _ISR_Get_level() / _ISR_Set_level() for re-enabling
334          interrupts rather than messing with MSR directly;
335          these macros:
336            o implement compiler memory barrier
337                o will handle multiple levels (e500 'critical' interrupts)
338                  if they are ever supported.
339        - decrementer irqs are also shareable - added list traversal.
340
3412007-12-01      Till Straumann <strauman@slac.stanford.edu>
342
343        * shared/irq/irq_supp.h: Make sure BSP_SHARED_HANDLER_SUPPORT
344        is set. The shared irq manager supports shared interrupts
345        (but requires also that the PIC-driver supports them by
346        traversing the list of shared handlers).
347        Declare C_dispatch_irq_handler() which must be defined
348        (like the other routines declared in this header) by the
349        PIC-driver.
350
3512007-12-01      Till Straumann <strauman@slac.stanford.edu>
352
353        * shared/clock/p_clock.c: (run-time) check for e500-cpu
354        and install different ISR for that type of CPU.
355
3562007-12-01      Till Straumann <strauman@slac.stanford.edu>
357
358        * shared/pci/detect_raven_bridge.c: use ifdef mvme2100
359        rather than ifdef mpc824x so that we don't depend on
360        compile-time CPU flavor. Eventually, this should become
361        a run-time check.
362
3632007-12-01      Till Straumann <strauman@slac.stanford.edu>
364
365        * shared/vectors/vectors.h: Give the BSP_Exception_frame
366        struct a name.
367
3682007-12-01      Till Straumann <strauman@slac.stanford.edu>
369
370        * shared/vme/vmeconfig.c: Include <libcpu/bat.h> only
371        if the BSP-specific configuration header (VMEConfig.h)
372        defines BSP_VME_BAT_IDX so that this file can be used
373        on CPUs w/o bats (e500).
374
3752007-11-30      Till Straumann <strauman@slac.stanford.edu>
376
377        * shared/startup/bspstart: removed _Cpu_table.exceptions_in_RAM.
378
3792007-11-30      Till Straumann <strauman@slac.stanford.edu>
380
381        * shared/startup/pretaskinghook.c: Replaced inclusion of
382        <bsp/consoleIo.h> by <rtems/bspIo.> (for printk) and
383        made it conditional on #ifdef SHOW_MORE_INIT_SETTINGS.
384
3852007-11-30      Till Straumann <strauman@slac.stanford.edu>
386
387        * shared/startup/bspstart.c: Removed excess /*, replaced
388        #ifdef checks for mpc8240 by #ifdef mvme2100; eventually
389        there should be run-time checks.
390
3912007-11-30      Till Straumann <strauman@slac.stanford.edu>
392
393        * shared/motorola/motorola.c: removed excess initializer
394        elements.
395
3962007-11-30      Till Straumann <strauman@slac.stanford.edu>
397
398        * shared/irq/irq.h, shared/irq/irq.c, shared/irq/irq_init.c,
399        shared/irq/irq_supp.h (added):
400        Removed 'is_processor_irq()' from irq.c; the BSP routines
401        BSP_enable_irq_at_pic()/BSP_disable_irq_at_pic() are required
402        to ignore processor irqs anyways. Removed
403        all BSP-defined constants from irq.c. This makes irq.c (almost)
404        binary-compatible among BSPs (ultimate goal is making 'shared'
405        a library).
406        Added a header (irq_supp.h) defining the interface between
407        the generic interrupt manager (irq.c) and the routines it
408        requires to be supplied by the BSP (eventually, these
409        should go into rtems/irq.h).

413        * shared/irq/irq.h, shared/irq/irq_init.c: Removed the definition
414        of ASM_IRQ_VECTOR_BASE; this symbol was only use to
415        initialize the irqBase member of the rtems_irq_global_settings
416        struct. However, irqBase is an rtems_irq_symbolic_name,
417        so using BSP_LOWEST_OFFSET is more appropriate.

431        for some intel + spansion flash chips (as found on mvme5500,
432        mvme6100 and mvme3100 boards).
433        A more appopriate place would probably be libchip but
434        I don't know if the API is acceptable and if the implementation
435        is generic enough (e.g., no CFI support) so I leave it here
436        for now.

444        * shared/console/uart.c: when draining UART during
445        initialization (wait for possible printk() activity
446        to finish) look at TEMT (fifo, holding-reg and shift-reg)
447        rather than THRE (fifo, holding-reg only). This resolved
448        some scrambled output issues for me.
449
450        Enhanced semantics: if BSP initializes BSPBaseBaud to a negative
451        value then the driver interprets the modulus as a speed value
452        and uses the current setting of the divisor to compute the
453        clock speed (BSPBaseBaud). This is useful if you have a board
454        that you know is initialized e.g., to 9600 but you
455        don't know the clock speed.

1248        This modification is part of the submitted modifications necessary
1249        to
1250        support the IBM PPC405 family.  This submission was reviewed by
1251        Thomas Doerfler <Thomas.Doerfler@imd-systems.de> who ensured it did
1252        not negatively impact the ppc403 BSPs.  The submission and tracking
1253        process was captured as PR50.
1254        * ChangeLog: Removed bogus comment on edit of generated file.
1255        * acinclude.m4: Added gen405 BSP.

1290        256 meg to allow operation on boards with larger RAM sizes.
1291        * shared/vectors/vectors_init.c: Modified to call 'generic' powerpc
1292        vector function (mpc60x_vector_is_valid) instead of MPC750  specific
1293        function to allow operation on boards with CPUs other than the
1294        MPC750.

1297
1298        * shared/bootloader/misc.c, shared/console/Makefile.am,
1299        shared/console/console.c, shared/console/consoleIo.h,
1300        shared/console/inch.c, shared/console/polled_io.c,

1306        shared/startup/bspstart.c, shared/vectors/vectors.S,
1307        shared/vectors/vectors.h, shared/vectors/vectors_init.c: Per PR216,
1308        "libbsp/powerpc/shared" BSP has been modified considerably with the
1309        goal to make it more flexible and reusable by other BSPs. The main
1310        strategies were: - eliminate hardcoded base addresses; devices use
1311        offsets and a BSP defined base address. - separate functionality
1312        into different files (e.g. reboot from inch.c to reboot.c) which can
1313        be overridden by a 'derived' BSP. - separate initialization code
1314        into separate files (e.g.  PCI bridge detection/initialization was
1315        separated from the more generic PCI access routines), also to make
1316        it easier for 'derived' BSPs to substitute their own initialization
1317        code. There are also a couple of enhancements and fixes: - IRQ
1318        handling code now has a hook for attaching a VME bridge. - OpenPIC
1319        is now explicitely initialized (polarities, senses). Eliminated the
1320        implicit assumption on the presence of an ISA PIC. - UART and
1321        console driver now supports more than 1 port. The current maximum of
1322        2 can easily be extended by enlarging a table (it would even be
1323        easier if the ISR API was not broken by design). - fixed polled_io.c
1324        so it correctly supports console on COM2 - fixed TLB invalidation
1325        code (start.S). - exception handler prints a stack backtrace. -
1326        added BSP_pciFindDevice() to scan the pci bus for a particular
1327        vendor/device/instance.

1331        * shared/startup/linkcmds: In support of gcc 3.1, added one of more
1332        of the sections .jcr, .rodata*, .data.*, .gnu.linkonce.s2.*,
1333        .gnu.linkonce.sb2.*, and .gnu.linkonce.s.*.  Spacing corrections and
1334        direction of segments to memory regions may also have been
1335        addressed.  This was a sweep across all BSPs.
1336
13372001-04-08      Joel Sherrill <joel@OARcorp.com>
1338
1339        * shared/startup/linkcmds: Per PR170, PR171, and PR172 add .eh_frame
1340
13412001-03-30      Eric Valette <valette@crf.canon.fr>
1342
1343        * shared/Makefile.am, shared/console/consoleIo.h,
1344        shared/include/bsp.h: These modifications are part of the conversion
1345        of the mpc8xx CPU to the "new exception processing model."
1346        * configure.in, motorola_powerpc/Makefile.am,
1347        motorola_powerpc/configure.in: These modifications are in support of
1348        switching the mpc8xx to the use the "new exception processing
1349        model."
1350
13512000-11-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

1354
13552000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
1356
1357        * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I
1358        $(RTEMS_TOPdir)/aclocal.
1359
13602000-11-01      Joel Sherrill <joel@OARcorp.com>
1361
1362        * shared/startup/bspstart.c: assoc.h, error.h, libio_.h, libio.h,
1363        and libcsupport.h moved from libc to lib/include/rtems and now must
1364        be referenced as <rtems/XXX.h>.   Header file order was cleaned up
1365        while doing this.
1366
13672000-10-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
1368
1369        * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros. Switch to
1370        GNU canonicalization.
1371
13722000-09-29      Charles-Antoine Gauthier <charles.gauthier@nrc.ca>
1373
1374        * shared/startup/linkcmds: Added lines so DWARF debug information
1375        would be available.  Otherwise gdb complains that the offsets for
1376        the debug info are incorrect and doesn't load the files.
1377
13782000-09-05      Joel Sherrill <joel@OARcorp.com>
1379
1380        * shared/start/start.S: Include proper files to compile.
