7
8        * shared/startup/pretaskinghook.c, shared/startup/sbrk.c:
9        Fixed PR#1335.
10
112008-10-02      Sebastian Huber <sebastian.huber@embedded-brains.de>
12
13        * shared/clock/clock.c: Update for status-checks.h changes.
14
152008-10-02      Joel Sherrill <joel.sherrill@oarcorp.com>
16
17        * shared/startup/bspgetworkarea.c: Change size_t to ssize_t on
18        bsp_get_work_area(). On 16-bit architectures, size_t can be 16-bits
19        which would limit the work area to 64K.
20
212008-09-22      Joel Sherrill <joel.sherrill@oarcorp.com>
22
23        * shared/console/inch.c, shared/startup/panic.c: Use standardized
24        bsp_cleanup() which can optionally print a message, poll for user to
25        press key, and call bsp_reset(). Using this eliminates the various
26        bsp_cleanup() implementations which had their own implementation and
27        variety of string constants.
28        * shared/console/bspreset.c: New file.
29        * shared/console/reboot.c: Removed.
30
312008-09-19      Joel Sherrill <joel.sherrill@oarcorp.com>
32
33        * shared/startup/bspgetworkarea.c, shared/startup/sbrk.c: Remove
34        warnings by switching to uintptr_t.
35
362008-09-19      Joel Sherrill <joel.sherrill@oarcorp.com>
37
38        * shared/start/start.S, shared/startup/bspgetworkarea.c,
39        shared/startup/bspstart.c, shared/startup/linkcmds: Modifications
40        which reflect those tested on psim. Hopefully they work on all
41        boards. The initialization stack is explicitly declared in the
42        linkcmds memory layout rather than magic math.
43
442008-09-16      Joel Sherrill <joel.sherrill@oarcorp.com>
45
46        * shared/include/nvram.h: Fix typo.
47
482008-09-16      Joel Sherrill <joel.sherrill@oarcorp.com>
49
50        * shared/clock/clock.c: Remove unnecessary includes of
51        rtems/libcsupport.h and rtems/libio.h.
52
532008-09-15      Joel Sherrill <joel.sherrill@oarcorp.com>
54
55        * shared/startup/bspstart.c, shared/startup/pretaskinghook.c: Add use
56        of bsp_get_work_area() in its own file and rely on BSP Framework to
57        perform more initialization.
58        * shared/startup/bspgetworkarea.c: New file.
59
602008-09-10      Joel Sherrill <joel.sherrill@oarcorp.com>
61
62        * shared/startup/bspstart.c: Review of all bsp_cleanup()
63        implementations. In this phase, all prototypes were removed from
64        bsp.h and empty implementations were removed and made to use the
65        shared stub.
66
672008-09-08      Joel Sherrill <joel.sherrill@oarcorp.com>
68
69        * acinclude.m4: Add tqm8xx.
70
712008-09-08      Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>
72
73        * tqm8xx: New BSP.
74
752008-09-06      Ralf Corsépius <ralf.corsepius@rtems.org>
76
77        * shared/irq/irq.c: Convert to "bool".
78
792008-09-05      Joel Sherrill <joel.sherrill@OARcorp.com>
80
81        * shared/clock/clock.c: The Shared Memory Driver no longer requires the
82        special IOCTL in Clock_control. This was a hack which has existed
83        since before the Classic API Timer Manager was implemented. All
84        implementations of and references to Clock_control were removed.
85
862008-09-05      Ralf Corsépius <ralf.corsepius@rtems.org>
87
88        * shared/console/inch.c: Convert to "bool".
89
902008-08-28      Till Straumann <strauman@slac.stanford.edu>
91
92        * shared/vme/vme_universe.c: added implementation for
93        BSP_VMEResetBus().
94
952008-08-20      Ralf Corsépius <ralf.corsepius@rtems.org>
96
97        * shared/flash/flash.c, shared/irq/irq_init.c: Add missing
98        prototypes.
99        * shared/showbats.c, shared/console/inch.c, shared/irq/irq_init.c,
100        shared/pci/detect_raven_bridge.c, shared/startup/bspstart.c,
101        shared/startup/zerobss.c, shared/vme/vmeconfig.c,
102        startup/exit.c: Add missing prototypes.
103
1042008-08-19      Sebastian Huber <sebastian.huber@embedded-brains.de>
105
106        * shared/clock/clock.c: Fixed warnings.
107
1082008-07-18      Sebastian Huber <sebastian.huber@embedded-brains.de>
109
110        * shared/clock/clock.c: Update due to powerpc-utilty.h changes.
111
1122008-07-14      Sebastian Huber <sebastian.huber@embedded-brains.de>
113
114        * mpc55xxevb: New BSP.
115
1162008-07-14      Thomas Doefler <Thomas.Doerfler@embedded-brains.de>
117        * haleakala: added new BSP
118
1192008-07-11      Sebastian Huber <sebastian.huber@embedded-brains.de>
120
121        * ep1a/startup/bspstart.c, mvme3100/startup/bspstart.c,
122        mvme5500/startup/bspstart.c, psim/startup/bspstart.c,
123        shared/startup/bspstart.c: The usage of SPRG0 as changed.  It is now
124        used to store the interrupt disable mask.  See bootcard.c and
125        ppc_exc_initialize() for default initialization.
126
127        Update to new exception initialization routine ppc_exc_initialize().
128        The exception low level code has changed, see libcpu/powerpc/ChangeLog.
129
130        * gen5200/startup/bspstart.c, mbx8xx/startup/bspstart.c,
131        mpc8260ads/startup/bspstart.c, ss555/startup/bspstart.c,
132        virtex/startup/bspstart.c: The usage of SPRG0 as changed.  It is now
133        used to store the interrupt disable mask.  See bootcard.c for default
134        initialization.
135
1362008-07-10      Till Straumann <strauman@slac.stanford.edu>
137
138        * shared/flash/spansionFlash.c: removed "m" memory
139        operands.
140
1412008-07-09      Sebastian Huber <sebastian.huber@embedded-brains.de>
142
143        * shared/clock/clock.c: Alternative clock driver.  Uses exception handler
144        directly.  Supports special variants for Book E and e300 cores.  For
145        standard decrementer CPUs the new decrementer value is calculated with
146        reference to a time base so that a time drift is avoided.
147
1482008-07-01      Joel Sherrill <joel.sherrill@oarcorp.com>
149
150        * shared/uboot_getenv.c: New file.
151
1522008-06-02      Joel Sherrill <joel.sherrill@oarcorp.com>
153
154        * shared/startup/panic.c: Convention calls for leading underscore on
155        private RTEMS variables.
156
1572008-05-23      Till Straumann <strauman@slac.stanford.edu>
158
159        * shared/startup/pretaskinghook.c: removed declaration
160        of BSP_vme_config() (which is already declared in
161        <bsp/VME.h>. Removed test for NULL-ness of BSP_vme_config;
162        gcc doesn't seem to understand that the linker may
163        define this to be NULL... Silences a compiler warning
164        (and users can always provide an empty routine).
165
1662008-05-22      Till Straumann <strauman@slac.stanford.edu>
167
168        * shared/startup/linkcmds, shared/startup/zerobss.c:
169        introduced '__bss_end'; assuming that __rtems_end
170        coincides with the end of .bss for the purpose of
171        zeroing .bss is very dangerous.
172
1732008-05-22      Joel Sherrill <joel.sherrill@OARcorp.com>
174
175        * shared/console/console.c: Fix typo.
176
1772008-05-22      Joel Sherrill <joel.sherrill@oarcorp.com>
178
179        * shared/console/console.c: Remove explicit switch and call
180        termios_baud_to_number().
181
1822008-05-15      Joel Sherrill <joel.sherrill@OARcorp.com>
183
184        * shared/startup/pretaskinghook.c: Add capability for bootcard.c BSP
185        Initialization Framework to ask the BSP where it has memory for the
186        RTEMS Workspace and C Program Heap. These collectively are referred
187        to as work area. If the BSP supports this, then it does not have to
188        include code to split the available memory between the two areas.
189        This reduces the amount of code in the BSP specific bspstart.c file.
190        Additionally, the shared framework can initialize the C Library, call
191        rtems_debug_enable(), and dirty the work area memory. Until most/all
192        BSPs support this new capability, if the BSP supports this, it should
193        call RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION from its configure.ac.
194        When the transition is complete, this autoconf macro can be removed.
195
1962008-05-12      Joel Sherrill <joel.sherrill@OARcorp.com>
197
198        * shared/startup/bspstart.c: Refactored and renamed initialization
199        routines to rtems_initialize_data_structures,
200        rtems_initialize_before_drivers, rtems_initialize_device_drivers, and
201        rtems_initialize_start_multitasking. This opened the sequence up so
202        that bootcard() could provide a more robust and flexible framework
203        which is easier to explain and understand. This also lays the
204        groundwork for sharing the division of available memory between the
205        RTEMS workspace and heap and the C library initialization across all
206        BSPs.
207
2082008-03-21      Till Straumann <strauman@slac.stanford.edu>
209
210        * shared/console/uart.c: In IRQ driven mode also
211        keep reading chars while they are available (fifo
212        could be enabled).
213
2142008-03-19      Till Straumann <strauman@slac.stanford.edu>
215
216        * shared/console/console.c, shared/console/uart.c,
217        shared/console/uart.h: added support for task-driven
218        console.
219
2202008-03-19      Till Straumann <strauman@slac.stanford.edu>
221
222        * shared/startup/pretaskinghook.c: install pointer
223        to rtems_malloc_sbrk_helpers_table. This (and derived)
224        BSPs rely on sbrk delivering even the first/initial
225        chunk of memory.
226
2272008-03-03      Joel Sherrill <joel.sherrill@OARcorp.com>
228
229        * shared/startup/linkcmds: Add wildcard to gcc_except_table section so
230        programs compiled with gcc 4.3.x can link.
231
2322008-02-19      Ralf Corsépius <ralf.corsepius@rtems.org>
233
234        * gen405: Remove (Abandoned).
235        * helas403: Remove (Abandoned).
236        * acinclude: Regenerate.
237
2382007-12-14      Joel Sherrill <joel.sherrill@oarcorp.com>
239
240        * acinclude.m4, gen5200/irq/irq.c, gen5200/startup/bspclean.c: Add
241        mvme3100.
242
2432007-12-11      Joel Sherrill <joel.sherrill@OARcorp.com>
244
245        * shared/startup/bspstart.c, shared/startup/pretaskinghook.c: Eliminate
246        copies of the Configuration Table. Use the RTEMS provided accessor
247        macros to obtain configuration fields.
248
2492007-12-10      Till Straumann <strauman@slac.stanford.edu>
250
251        * Makefile.am, start/preload.S: moved preload.S
252        to ../shared/start.
253
2542007-12-10      Till Straumann <strauman@slac.stanford.edu>
255
256        * shared/irq/irq_asm.S, shared/vectors/vectors.h:
257        renamed ASM_BOOKE_PIT_VECTOR to ASM_BOOKE_DEC_VECTOR
258        to be closer to 'official' nomenclature.
259
2602007-12-10      Till Straumann <strauman@slac.stanford.edu>
261
262        * shared/openpic/openpic.c: fixed wrong register
263        address in openpic_gettimer().
264
2652007-12-10      Till Straumann <strauman@slac.stanford.edu>
266
267        * shared/motorola/vpd.c, shared/motorola/vpd.h:
268        added code (originally developed for 'beatnik')
269        to read MotLoad VPD data from i2c eeprom.
270
2712007-12-10      Till Straumann <strauman@slac.stanford.edu>
272
273        * shared/vectors/README.deprecated, shared/irq/README.deprecated:
274        added READMEs stating that certain files should not be
275        copy/paste/modified when creating new BSPs. New BSPs
276        are encouraged to use the new library under
277        libcpu/powerpc/new-exceptions/bspsupport.
278
2792007-12-10      Till Straumann <strauman@slac.stanford.edu>
280       
281        * shared/vectors/vectors_entry.S, motorola_powerpc/bsp_specs,
282        shared/start/vectors_entry.S: moved vectors_entry.S to
283        'start' subdir and made a start file rather than
284        element of vectors.rel (it should always be linked but
285        won't if it is the sole member of vectors.rel).
286
2872007-12-08      Till Straumann <strauman@slac.stanford.edu>
288
289        * shared/vme/vme_universe.c: fixed wrong initialization
290        routine when using Tsi148 driver.
291
2922007-12-08      Till Straumann <strauman@slac.stanford.edu>
293
294        * Makefile.am: merged shared/vme/vme_universe.c and
295        shared/vme/vme_universe_dma.c into one file.
296        Added support for Tsi148 driver (DMA).
297
2982007-12-08      Till Straumann <strauman@slac.stanford.edu>
299
300        * shared/vme/VMEConfig.h, shared/vme/vme_universe.c:
301        added support for Tsi148 bridge; BSP can define which
302        bridge driver to use from VMEConfig.h.
303        Added 'err' macro parameter to BSP_VME_INSTALL_IRQ_MGR(err)
304        macro so that an error status can be passed back.
305
3062007-12-08      Till Straumann <strauman@slac.stanford.edu>
307
308        * irq_supp.h: was moved from shared/irq to
309        libcpu/powerpc/new-exceptions/bspsupport.
310
3112007-12-08      Till Straumann <strauman@slac.stanford.edu>
312
313        * ep1a/irq/irq.c, gen5200/irq/irq.c, gen83xx/irq/irq_init.c,
314        mbx8xx/irq/irq.c, mpc8260ads/irq/irq.c, mvme5500/irq/irq.c,
315        psim/irq/no_pic.c, score603e/irq/irq.c, shared/irq/irq_supp.h,
316        shared/irq/openpic_i8259_irq.c, virtex/irq/irq_init.c:
317        let C_dispatch_irq_handler() return zero to indicate to
318        low-level exception handling code that the exception
319        was handled (not used yet).
320
3212007-12-08      Till Straumann <strauman@slac.stanford.edu>
322
323        *shared/irq/irq_supp.h: removed cpp test for
324        BSP_SHARED_HANDLER_SUPPORT; BSPs using irq_supp.h
325        *must* implement shared handlers.
326
3272007-12-06      Till Straumann <strauman@slac.stanford.edu>
328
329        * shared/openpic/openpic.c, shared/openpic/openpic.h:
330        added routines to set timer period and interupt mask
331        and to read current count.
332
3332007-12-06      Till Straumann <strauman@slac.stanford.edu>
334
335        * virtex/irq/irq_init.c: use new ASM_xxx_VECTOR names.
336
3372007-12-06      Till Straumann <strauman@slac.stanford.edu>
338
339        * shared/vectors/vectors_init.c: replaced
340        switch ( current_ppc_cpu ) { } check by feature check.
341
3422007-12-06      Till Straumann <strauman@slac.stanford.edu>
343
344        * shared/irq/irq_asm.S, shared/vectors/vectors.S:
345        Replaced use of hardcoded PPC_EXC_MSR_BITS by a
346        run-time method to determine these bits (use settings
347        effective before exception occurred).
348        Replaced use of hardcoded ASM_VECTORS_CRITICAL by
349        'bsp_raw_vector_is_405_critical' variable.
350
3512007-12-05      Till Straumann <strauman@slac.stanford.edu>
352
353        * shared/irq/irq_supp.h: removed stray '*/'. Removed
354        inclusion of <stdlib.h> which is unnecessary and broke
355        if_dc in an obscure way (due to malloc/free redefinition
356        in the networking code).
357
3582007-12-05      Till Straumann <strauman@slac.stanford.edu>
359
360        * shared/irq/irq_asm.S, shared/vectors/vectors.S,
361        shared/vectors/vectors.h, shared/vectors/vectors_init.c:
362        Converted exception vector names to new ones
363        (qualified by <cpu_type> if non-std ppc exceptions).
364
365
3662007-12-04      Till Straumann <strauman@slac.stanford.edu>
367
368        * shared/startup/bspstart.c: export BSP_commandline_string
369        variable.
370
3712007-12-04      Till Straumann <strauman@slac.stanford.edu>
372
373        * shared/flash/flash.c: added lazy init of driver
374        from BSP_flashWriteFile().
375
3762007-12-04      Joel Sherrill <joel.sherrill@OARcorp.com>
377
378        * shared/startup/bspstart.c: Move interrupt_stack_size field from CPU
379        Table to Configuration Table. Eliminate CPU Table from all ports.
380        Delete references to CPU Table in all forms.
381
3822007-12-03      Joel Sherrill <joel.sherrill@oarcorp.com>
383
384        * shared/irq/irq.c: Spacing.
385
3862007-12-03      Joel Sherrill <joel.sherrill@OARcorp.com>
387
388        * shared/startup/bspstart.c: Moved most of the remaining CPU Table
389        fields to the Configuration Table. This included pretasking_hook,
390        predriver_hook, postdriver_hook, idle_task, do_zero_of_workspace,
391        extra_mpci_receive_server_stack, stack_allocate_hook, and
392        stack_free_hook. As a side-effect of this effort some multiprocessing
393        code was made conditional and some style clean up occurred.
394
3952007-12-03      Joel Sherrill <joel.sherrill@oarcorp.com>
396
397        * shared/irq/irq.c, shared/irq/irq_supp.h: Correct conditionals and
398        includes.
399
4002007-12-02      Till Straumann <strauman@slac.stanford.edu>
401
402        * shared/irq/i8259.c, shared/irq/irq.h, shared/irq/irq_supp.h,
403        shared/irq/openpic_i8259_irq.c: BSP_disable_irq_at_pic(),

411        * shared/openpic/openpic.c shared/openpic/openpic.h,
412        shared/irq/irq_init.c: added more parameters to
413        openpic_init() so that more details of the configuration
414        can be overridden/set from the BSP. Moved setup of
415        the EPIC-specific EOI delay from BSP code into openpic_init()
416        using the new 'epic_freq' parameter.

419        * shared/openpic/openpic.c, shared/openpic/openpic.h:
420        - eliminated conditional compilation (#ifdef mpc8240)
421          The difference in register-layout between the EPIC
422          and the std. openPIC is handled by an offset parameter
423          which can be set at run-time (initialization) with
424          a new routine 'openpic_set_src_offset()'.
425        - allow BSP to define symbol BSP_OPEN_PIC_BIG_ENDIAN
426          which builds the driver for big-endian register access
427          (mpc8540).
428        - openpic_disable_irq() now returns the old state so
429          that it can be restored later.

436        - use _ISR_Get_level() / _ISR_Set_level() for re-enabling
437          interrupts rather than messing with MSR directly;
438          these macros:
439            o implement compiler memory barrier
440                o will handle multiple levels (e500 'critical' interrupts)
441                  if they are ever supported.

448        (but requires also that the PIC-driver supports them by
449        traversing the list of shared handlers).

500
501        * shared/irq/irq.h, shared/irq/irq.c, shared/irq/irq_init.c,
502        shared/irq/irq_supp.h (added):
503        Removed 'is_processor_irq()' from irq.c; the BSP routines
504        BSP_enable_irq_at_pic()/BSP_disable_irq_at_pic() are required
505        to ignore processor irqs anyways. Removed
506        all BSP-defined constants from irq.c. This makes irq.c (almost)
507        binary-compatible among BSPs (ultimate goal is making 'shared'
508        a library).
509        Added a header (irq_supp.h) defining the interface between
510        the generic interrupt manager (irq.c) and the routines it
511        requires to be supplied by the BSP (eventually, these
512        should go into rtems/irq.h).

517        of ASM_IRQ_VECTOR_BASE; this symbol was only use to
518        initialize the irqBase member of the rtems_irq_global_settings
519        struct. However, irqBase is an rtems_irq_symbolic_name,
520        so using BSP_LOWEST_OFFSET is more appropriate.

533        Added flash programmer API, implementation and chip drivers
534        for some intel + spansion flash chips (as found on mvme5500,
535        mvme6100 and mvme3100 boards).
536        A more appopriate place would probably be libchip but
537        I don't know if the API is acceptable and if the implementation
538        is generic enough (e.g., no CFI support) so I leave it here
539        for now.

548        initialization (wait for possible printk() activity
549        to finish) look at TEMT (fifo, holding-reg and shift-reg)
550        rather than THRE (fifo, holding-reg only). This resolved
551        some scrambled output issues for me.
552
553        Enhanced semantics: if BSP initializes BSPBaseBaud to a negative
554        value then the driver interprets the modulus as a speed value
555        and uses the current setting of the divisor to compute the
556        clock speed (BSPBaseBaud). This is useful if you have a board
557        that you know is initialized e.g., to 9600 but you
558        don't know the clock speed.

1192        console to install/retrieve a BREAK-IRQ callback.  The callback
1193        routine (if installed) is invoked from the UART ISR when a BREAK
1194        interrupt is detected.  This can be used e.g. to enforce a "hotkey"

1410        shared/vectors/vectors.h, shared/vectors/vectors_init.c: Per PR216,
1411        "libbsp/powerpc/shared" BSP has been modified considerably with the
1412        goal to make it more flexible and reusable by other BSPs. The main
1413        strategies were: - eliminate hardcoded base addresses; devices use
1414        offsets and a BSP defined base address. - separate functionality
1415        into different files (e.g. reboot from inch.c to reboot.c) which can
1416        be overridden by a 'derived' BSP. - separate initialization code
1417        into separate files (e.g.  PCI bridge detection/initialization was
1418        separated from the more generic PCI access routines), also to make
1419        it easier for 'derived' BSPs to substitute their own initialization
1420        code. There are also a couple of enhancements and fixes: - IRQ
1421        handling code now has a hook for attaching a VME bridge. - OpenPIC
1422        is now explicitely initialized (polarities, senses). Eliminated the
1423        implicit assumption on the presence of an ISA PIC. - UART and
1424        console driver now supports more than 1 port. The current maximum of
1425        2 can easily be extended by enlarging a table (it would even be
1426        easier if the ISR API was not broken by design). - fixed polled_io.c
1427        so it correctly supports console on COM2 - fixed TLB invalidation
1428        code (start.S). - exception handler prints a stack backtrace. -
1429        added BSP_pciFindDevice() to scan the pci bus for a particular
1430        vendor/device/instance.

1436        .gnu.linkonce.sb2.*, and .gnu.linkonce.s.*.  Spacing corrections and
