2        * haleakala: added new BSP
3
42008-07-11      Sebastian Huber <sebastian.huber@embedded-brains.de>
5
6        * ep1a/startup/bspstart.c, mvme3100/startup/bspstart.c,
7        mvme5500/startup/bspstart.c, psim/startup/bspstart.c,
8        shared/startup/bspstart.c: The usage of SPRG0 as changed.  It is now
9        used to store the interrupt disable mask.  See bootcard.c and
10        ppc_exc_initialize() for default initialization.
11
12        Update to new exception initialization routine ppc_exc_initialize().
13        The exception low level code has changed, see libcpu/powerpc/ChangeLog.
14
15        * gen5200/startup/bspstart.c, mbx8xx/startup/bspstart.c,
16        mpc8260ads/startup/bspstart.c, ss555/startup/bspstart.c,
17        virtex/startup/bspstart.c: The usage of SPRG0 as changed.  It is now
18        used to store the interrupt disable mask.  See bootcard.c for default
19        initialization.
20
212008-07-10      Till Straumann <strauman@slac.stanford.edu>
22
23        * shared/flash/spansionFlash.c: removed "m" memory
24        operands.
25
262008-07-09      Sebastian Huber <sebastian.huber@embedded-brains.de>
27
28        * shared/clock/clock.c: Alternative clock driver.  Uses exception handler
29        directly.  Supports special variants for Book E and e300 cores.  For
30        standard decrementer CPUs the new decrementer value is calculated with
31        reference to a time base so that a time drift is avoided.
32
332008-07-01      Joel Sherrill <joel.sherrill@oarcorp.com>
34
35        * shared/uboot_getenv.c: New file.
36
372008-06-02      Joel Sherrill <joel.sherrill@oarcorp.com>
38
39        * shared/startup/panic.c: Convention calls for leading underscore on
40        private RTEMS variables.
41
422008-05-23      Till Straumann <strauman@slac.stanford.edu>
43
44        * shared/startup/pretaskinghook.c: removed declaration
45        of BSP_vme_config() (which is already declared in
46        <bsp/VME.h>. Removed test for NULL-ness of BSP_vme_config;
47        gcc doesn't seem to understand that the linker may
48        define this to be NULL... Silences a compiler warning
49        (and users can always provide an empty routine).
50
512008-05-22      Till Straumann <strauman@slac.stanford.edu>
52
53        * shared/startup/linkcmds, shared/startup/zerobss.c:
54        introduced '__bss_end'; assuming that __rtems_end
55        coincides with the end of .bss for the purpose of
56        zeroing .bss is very dangerous.
57
582008-05-22      Joel Sherrill <joel.sherrill@OARcorp.com>
59
60        * shared/console/console.c: Fix typo.
61
622008-05-22      Joel Sherrill <joel.sherrill@oarcorp.com>
63
64        * shared/console/console.c: Remove explicit switch and call
65        termios_baud_to_number().
66
672008-05-15      Joel Sherrill <joel.sherrill@OARcorp.com>
68
69        * shared/startup/pretaskinghook.c: Add capability for bootcard.c BSP
70        Initialization Framework to ask the BSP where it has memory for the
71        RTEMS Workspace and C Program Heap. These collectively are referred
72        to as work area. If the BSP supports this, then it does not have to
73        include code to split the available memory between the two areas.
74        This reduces the amount of code in the BSP specific bspstart.c file.
75        Additionally, the shared framework can initialize the C Library, call
76        rtems_debug_enable(), and dirty the work area memory. Until most/all
77        BSPs support this new capability, if the BSP supports this, it should
78        call RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION from its configure.ac.
79        When the transition is complete, this autoconf macro can be removed.
80
812008-05-12      Joel Sherrill <joel.sherrill@OARcorp.com>
82
83        * shared/startup/bspstart.c: Refactored and renamed initialization
84        routines to rtems_initialize_data_structures,
85        rtems_initialize_before_drivers, rtems_initialize_device_drivers, and
86        rtems_initialize_start_multitasking. This opened the sequence up so
87        that bootcard() could provide a more robust and flexible framework
88        which is easier to explain and understand. This also lays the
89        groundwork for sharing the division of available memory between the
90        RTEMS workspace and heap and the C library initialization across all
91        BSPs.
92
932008-03-21      Till Straumann <strauman@slac.stanford.edu>
94
95        * shared/console/uart.c: In IRQ driven mode also
96        keep reading chars while they are available (fifo
97        could be enabled).
98
992008-03-19      Till Straumann <strauman@slac.stanford.edu>
100
101        * shared/console/console.c, shared/console/uart.c,
102        shared/console/uart.h: added support for task-driven
103        console.
104
1052008-03-19      Till Straumann <strauman@slac.stanford.edu>
106
107        * shared/startup/pretaskinghook.c: install pointer
108        to rtems_malloc_sbrk_helpers_table. This (and derived)
109        BSPs rely on sbrk delivering even the first/initial
110        chunk of memory.
111
1122008-03-03      Joel Sherrill <joel.sherrill@OARcorp.com>
113
114        * shared/startup/linkcmds: Add wildcard to gcc_except_table section so
115        programs compiled with gcc 4.3.x can link.
116
1172008-02-19      Ralf Corsépius <ralf.corsepius@rtems.org>
118
119        * gen405: Remove (Abandoned).
120        * helas403: Remove (Abandoned).
121        * acinclude: Regenerate.
122
1232007-12-14      Joel Sherrill <joel.sherrill@oarcorp.com>
124
125        * acinclude.m4, gen5200/irq/irq.c, gen5200/startup/bspclean.c: Add
126        mvme3100.
127
1282007-12-11      Joel Sherrill <joel.sherrill@OARcorp.com>
129
130        * shared/startup/bspstart.c, shared/startup/pretaskinghook.c: Eliminate
131        copies of the Configuration Table. Use the RTEMS provided accessor
132        macros to obtain configuration fields.
133
1342007-12-10      Till Straumann <strauman@slac.stanford.edu>
135
136        * Makefile.am, start/preload.S: moved preload.S
137        to ../shared/start.
138
1392007-12-10      Till Straumann <strauman@slac.stanford.edu>
140
141        * shared/irq/irq_asm.S, shared/vectors/vectors.h:
142        renamed ASM_BOOKE_PIT_VECTOR to ASM_BOOKE_DEC_VECTOR
143        to be closer to 'official' nomenclature.
144
1452007-12-10      Till Straumann <strauman@slac.stanford.edu>
146
147        * shared/openpic/openpic.c: fixed wrong register
148        address in openpic_gettimer().
149
1502007-12-10      Till Straumann <strauman@slac.stanford.edu>
151
152        * shared/motorola/vpd.c, shared/motorola/vpd.h:
153        added code (originally developed for 'beatnik')
154        to read MotLoad VPD data from i2c eeprom.
155
1562007-12-10      Till Straumann <strauman@slac.stanford.edu>
157
158        * shared/vectors/README.deprecated, shared/irq/README.deprecated:
159        added READMEs stating that certain files should not be
160        copy/paste/modified when creating new BSPs. New BSPs
161        are encouraged to use the new library under
162        libcpu/powerpc/new-exceptions/bspsupport.
163
1642007-12-10      Till Straumann <strauman@slac.stanford.edu>
165       
166        * shared/vectors/vectors_entry.S, motorola_powerpc/bsp_specs,
167        shared/start/vectors_entry.S: moved vectors_entry.S to
168        'start' subdir and made a start file rather than
169        element of vectors.rel (it should always be linked but
170        won't if it is the sole member of vectors.rel).
171
1722007-12-08      Till Straumann <strauman@slac.stanford.edu>
173
174        * shared/vme/vme_universe.c: fixed wrong initialization
175        routine when using Tsi148 driver.
176
1772007-12-08      Till Straumann <strauman@slac.stanford.edu>
178
179        * Makefile.am: merged shared/vme/vme_universe.c and
180        shared/vme/vme_universe_dma.c into one file.
181        Added support for Tsi148 driver (DMA).
182
1832007-12-08      Till Straumann <strauman@slac.stanford.edu>
184
185        * shared/vme/VMEConfig.h, shared/vme/vme_universe.c:
186        added support for Tsi148 bridge; BSP can define which
187        bridge driver to use from VMEConfig.h.
188        Added 'err' macro parameter to BSP_VME_INSTALL_IRQ_MGR(err)
189        macro so that an error status can be passed back.
190
1912007-12-08      Till Straumann <strauman@slac.stanford.edu>
192
193        * irq_supp.h: was moved from shared/irq to
194        libcpu/powerpc/new-exceptions/bspsupport.
195
1962007-12-08      Till Straumann <strauman@slac.stanford.edu>
197
198        * ep1a/irq/irq.c, gen5200/irq/irq.c, gen83xx/irq/irq_init.c,
199        mbx8xx/irq/irq.c, mpc8260ads/irq/irq.c, mvme5500/irq/irq.c,
200        psim/irq/no_pic.c, score603e/irq/irq.c, shared/irq/irq_supp.h,
201        shared/irq/openpic_i8259_irq.c, virtex/irq/irq_init.c:
202        let C_dispatch_irq_handler() return zero to indicate to
203        low-level exception handling code that the exception
204        was handled (not used yet).
205
2062007-12-08      Till Straumann <strauman@slac.stanford.edu>
207
208        *shared/irq/irq_supp.h: removed cpp test for
209        BSP_SHARED_HANDLER_SUPPORT; BSPs using irq_supp.h
210        *must* implement shared handlers.
211
2122007-12-06      Till Straumann <strauman@slac.stanford.edu>
213
214        * shared/openpic/openpic.c, shared/openpic/openpic.h:
215        added routines to set timer period and interupt mask
216        and to read current count.
217
2182007-12-06      Till Straumann <strauman@slac.stanford.edu>
219
220        * virtex/irq/irq_init.c: use new ASM_xxx_VECTOR names.
221
2222007-12-06      Till Straumann <strauman@slac.stanford.edu>
223
224        * shared/vectors/vectors_init.c: replaced
225        switch ( current_ppc_cpu ) { } check by feature check.
226
2272007-12-06      Till Straumann <strauman@slac.stanford.edu>
228
229        * shared/irq/irq_asm.S, shared/vectors/vectors.S:
230        Replaced use of hardcoded PPC_EXC_MSR_BITS by a
231        run-time method to determine these bits (use settings
232        effective before exception occurred).
233        Replaced use of hardcoded ASM_VECTORS_CRITICAL by
234        'bsp_raw_vector_is_405_critical' variable.
235
2362007-12-05      Till Straumann <strauman@slac.stanford.edu>
237
238        * shared/irq/irq_supp.h: removed stray '*/'. Removed
239        inclusion of <stdlib.h> which is unnecessary and broke
240        if_dc in an obscure way (due to malloc/free redefinition
241        in the networking code).
242
2432007-12-05      Till Straumann <strauman@slac.stanford.edu>
244
245        * shared/irq/irq_asm.S, shared/vectors/vectors.S,
246        shared/vectors/vectors.h, shared/vectors/vectors_init.c:
247        Converted exception vector names to new ones
248        (qualified by <cpu_type> if non-std ppc exceptions).
249
250
2512007-12-04      Till Straumann <strauman@slac.stanford.edu>
252
253        * shared/startup/bspstart.c: export BSP_commandline_string
254        variable.
255
2562007-12-04      Till Straumann <strauman@slac.stanford.edu>
257
258        * shared/flash/flash.c: added lazy init of driver
259        from BSP_flashWriteFile().
260
2612007-12-04      Joel Sherrill <joel.sherrill@OARcorp.com>
262
263        * shared/startup/bspstart.c: Move interrupt_stack_size field from CPU
264        Table to Configuration Table. Eliminate CPU Table from all ports.
265        Delete references to CPU Table in all forms.
266
2672007-12-03      Joel Sherrill <joel.sherrill@oarcorp.com>
268
269        * shared/irq/irq.c: Spacing.
270
2712007-12-03      Joel Sherrill <joel.sherrill@OARcorp.com>
272
273        * shared/startup/bspstart.c: Moved most of the remaining CPU Table
274        fields to the Configuration Table. This included pretasking_hook,
275        predriver_hook, postdriver_hook, idle_task, do_zero_of_workspace,
276        extra_mpci_receive_server_stack, stack_allocate_hook, and
277        stack_free_hook. As a side-effect of this effort some multiprocessing
278        code was made conditional and some style clean up occurred.
279
2802007-12-03      Joel Sherrill <joel.sherrill@oarcorp.com>
281
282        * shared/irq/irq.c, shared/irq/irq_supp.h: Correct conditionals and
283        includes.
284
2852007-12-02      Till Straumann <strauman@slac.stanford.edu>
286
287        * shared/irq/i8259.c, shared/irq/irq.h, shared/irq/irq_supp.h,
288        shared/irq/openpic_i8259_irq.c: BSP_disable_irq_at_pic(),
289        openpic_disable_irq(), BSP_irq_disable_at_i8259s() now return
290        0/1 if irq was disabled/enabled prior to disabling.
291        irq_supp.h now exports a inline helper routine for scanning
292        a list of shared handlers; to be used by PIC drivers.
293
2942007-12-02      Till Straumann <strauman@slac.stanford.edu>
295
296        * shared/openpic/openpic.c shared/openpic/openpic.h,
297        shared/irq/irq_init.c: added more parameters to
298        openpic_init() so that more details of the configuration
299        can be overridden/set from the BSP. Moved setup of
300        the EPIC-specific EOI delay from BSP code into openpic_init()
301        using the new 'epic_freq' parameter.
302
3032007-12-02      Till Straumann <strauman@slac.stanford.edu>
304        * shared/openpic/openpic.c, shared/openpic/openpic.h:
305        - eliminated conditional compilation (#ifdef mpc8240)
306          The difference in register-layout between the EPIC
307          and the std. openPIC is handled by an offset parameter
308          which can be set at run-time (initialization) with
309          a new routine 'openpic_set_src_offset()'.
310        - allow BSP to define symbol BSP_OPEN_PIC_BIG_ENDIAN
311          which builds the driver for big-endian register access
312          (mpc8540).
313        - openpic_disable_irq() now returns the old state so
314          that it can be restored later.
315
3162007-12-01      Till Straumann <strauman@slac.stanford.edu>
317
318        * shared/irq/openpic_i8259_irq.c:
319        - conditionally define 'irq_mask_or_tbl' only if
320          BSP_PCI_ISA_BRIDGE_IRQ is defined.
321        - use _ISR_Get_level() / _ISR_Set_level() for re-enabling
322          interrupts rather than messing with MSR directly;
323          these macros:
324            o implement compiler memory barrier
325                o will handle multiple levels (e500 'critical' interrupts)
326                  if they are ever supported.
327        - decrementer irqs are also shareable - added list traversal.
328
3292007-12-01      Till Straumann <strauman@slac.stanford.edu>
330
331        * shared/irq/irq_supp.h: Make sure BSP_SHARED_HANDLER_SUPPORT
332        is set. The shared irq manager supports shared interrupts
333        (but requires also that the PIC-driver supports them by
334        traversing the list of shared handlers).
335        Declare C_dispatch_irq_handler() which must be defined
336        (like the other routines declared in this header) by the
337        PIC-driver.
338
3392007-12-01      Till Straumann <strauman@slac.stanford.edu>
340
341        * shared/clock/p_clock.c: (run-time) check for e500-cpu
342        and install different ISR for that type of CPU.
343
3442007-12-01      Till Straumann <strauman@slac.stanford.edu>
345
346        * shared/pci/detect_raven_bridge.c: use ifdef mvme2100
347        rather than ifdef mpc824x so that we don't depend on
348        compile-time CPU flavor. Eventually, this should become
349        a run-time check.
350
3512007-12-01      Till Straumann <strauman@slac.stanford.edu>
352
353        * shared/vectors/vectors.h: Give the BSP_Exception_frame
354        struct a name.
355
3562007-12-01      Till Straumann <strauman@slac.stanford.edu>
357
358        * shared/vme/vmeconfig.c: Include <libcpu/bat.h> only
359        if the BSP-specific configuration header (VMEConfig.h)
360        defines BSP_VME_BAT_IDX so that this file can be used
361        on CPUs w/o bats (e500).
362
3632007-11-30      Till Straumann <strauman@slac.stanford.edu>
364
365        * shared/startup/bspstart: removed _Cpu_table.exceptions_in_RAM.
366
3672007-11-30      Till Straumann <strauman@slac.stanford.edu>
368
369        * shared/startup/pretaskinghook.c: Replaced inclusion of
370        <bsp/consoleIo.h> by <rtems/bspIo.> (for printk) and
371        made it conditional on #ifdef SHOW_MORE_INIT_SETTINGS.
372
3732007-11-30      Till Straumann <strauman@slac.stanford.edu>
374
375        * shared/startup/bspstart.c: Removed excess /*, replaced
376        #ifdef checks for mpc8240 by #ifdef mvme2100; eventually
377        there should be run-time checks.
378
3792007-11-30      Till Straumann <strauman@slac.stanford.edu>
380
381        * shared/motorola/motorola.c: removed excess initializer
382        elements.
383
3842007-11-30      Till Straumann <strauman@slac.stanford.edu>
385
386        * shared/irq/irq.h, shared/irq/irq.c, shared/irq/irq_init.c,
387        shared/irq/irq_supp.h (added):
388        Removed 'is_processor_irq()' from irq.c; the BSP routines
389        BSP_enable_irq_at_pic()/BSP_disable_irq_at_pic() are required
390        to ignore processor irqs anyways. Removed
391        all BSP-defined constants from irq.c. This makes irq.c (almost)
392        binary-compatible among BSPs (ultimate goal is making 'shared'
393        a library).
394        Added a header (irq_supp.h) defining the interface between
395        the generic interrupt manager (irq.c) and the routines it
396        requires to be supplied by the BSP (eventually, these
397        should go into rtems/irq.h).
398
3992007-11-30      Till Straumann <strauman@slac.stanford.edu>
400

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

432        * shared/console/uart.c: when draining UART during
433        initialization (wait for possible printk() activity
434        to finish) look at TEMT (fifo, holding-reg and shift-reg)
435        rather than THRE (fifo, holding-reg only). This resolved
436        some scrambled output issues for me.
437
438        Enhanced semantics: if BSP initializes BSPBaseBaud to a negative
439        value then the driver interprets the modulus as a speed value
440        and uses the current setting of the divisor to compute the
441        clock speed (BSPBaseBaud). This is useful if you have a board
442        that you know is initialized e.g., to 9600 but you
443        don't know the clock speed.

1236        This modification is part of the submitted modifications necessary
1237        to
1238        support the IBM PPC405 family.  This submission was reviewed by
1239        Thomas Doerfler <Thomas.Doerfler@imd-systems.de> who ensured it did
1240        not negatively impact the ppc403 BSPs.  The submission and tracking
1241        process was captured as PR50.
1242        * ChangeLog: Removed bogus comment on edit of generated file.
1243        * acinclude.m4: Added gen405 BSP.

1277        * shared/start/start.S: Increased BAT0 mapping of RAM from 64 meg to
1278        256 meg to allow operation on boards with larger RAM sizes.
1279        * shared/vectors/vectors_init.c: Modified to call 'generic' powerpc
1280        vector function (mpc60x_vector_is_valid) instead of MPC750  specific
1281        function to allow operation on boards with CPUs other than the
1282        MPC750.

1294        shared/startup/bspstart.c, shared/vectors/vectors.S,
1295        shared/vectors/vectors.h, shared/vectors/vectors_init.c: Per PR216,
1296        "libbsp/powerpc/shared" BSP has been modified considerably with the
1297        goal to make it more flexible and reusable by other BSPs. The main
1298        strategies were: - eliminate hardcoded base addresses; devices use
1299        offsets and a BSP defined base address. - separate functionality
1300        into different files (e.g. reboot from inch.c to reboot.c) which can
1301        be overridden by a 'derived' BSP. - separate initialization code
1302        into separate files (e.g.  PCI bridge detection/initialization was
1303        separated from the more generic PCI access routines), also to make
1304        it easier for 'derived' BSPs to substitute their own initialization
1305        code. There are also a couple of enhancements and fixes: - IRQ
1306        handling code now has a hook for attaching a VME bridge. - OpenPIC
1307        is now explicitely initialized (polarities, senses). Eliminated the
1308        implicit assumption on the presence of an ISA PIC. - UART and
1309        console driver now supports more than 1 port. The current maximum of
1310        2 can easily be extended by enlarging a table (it would even be
1311        easier if the ISR API was not broken by design). - fixed polled_io.c
1312        so it correctly supports console on COM2 - fixed TLB invalidation
1313        code (start.S). - exception handler prints a stack backtrace. -
1314        added BSP_pciFindDevice() to scan the pci bus for a particular
1315        vendor/device/instance.

1319        * shared/startup/linkcmds: In support of gcc 3.1, added one of more
1320        of the sections .jcr, .rodata*, .data.*, .gnu.linkonce.s2.*,
1321        .gnu.linkonce.sb2.*, and .gnu.linkonce.s.*.  Spacing corrections and
1322        direction of segments to memory regions may also have been
1323        addressed.  This was a sweep across all BSPs.
1324
13252001-04-08      Joel Sherrill <joel@OARcorp.com>
1326
1327        * shared/startup/linkcmds: Per PR170, PR171, and PR172 add .eh_frame

1330
1331        * shared/Makefile.am, shared/console/consoleIo.h,
1332        shared/include/bsp.h: These modifications are part of the conversion
1333        of the mpc8xx CPU to the "new exception processing model."
1334        * configure.in, motorola_powerpc/Makefile.am,
1335        motorola_powerpc/configure.in: These modifications are in support of
1336        switching the mpc8xx to the use the "new exception processing
1337        model."

13482000-11-01      Joel Sherrill <joel@OARcorp.com>
1349
1350        * shared/startup/bspstart.c: assoc.h, error.h, libio_.h, libio.h,
1351        and libcsupport.h moved from libc to lib/include/rtems and now must
1352        be referenced as <rtems/XXX.h>.   Header file order was cleaned up
1353        while doing this.
1354
13552000-10-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

13602000-09-29      Charles-Antoine Gauthier <charles.gauthier@nrc.ca>
1361
1362        * shared/startup/linkcmds: Added lines so DWARF debug information
1363        would be available.  Otherwise gdb complains that the offsets for
1364        the debug info are incorrect and doesn't load the files.
1365
