133        used to store the interrupt disable mask.  See bootcard.c and
134        ppc_exc_initialize() for default initialization.

1502008-07-09      Sebastian Huber <sebastian.huber@embedded-brains.de>
151
152        * shared/clock/clock.c: Alternative clock driver.  Uses exception handler
153        directly.  Supports special variants for Book E and e300 cores.  For
154        standard decrementer CPUs the new decrementer value is calculated with
155        reference to a time base so that a time drift is avoided.

164        private RTEMS variables.
165
1662008-05-23      Till Straumann <strauman@slac.stanford.edu>
167
168        * shared/startup/pretaskinghook.c: removed declaration
169        of BSP_vme_config() (which is already declared in
170        <bsp/VME.h>. Removed test for NULL-ness of BSP_vme_config;
171        gcc doesn't seem to understand that the linker may
172        define this to be NULL... Silences a compiler warning
173        (and users can always provide an empty routine).
174
1752008-05-22      Till Straumann <strauman@slac.stanford.edu>
176
177        * shared/startup/linkcmds, shared/startup/zerobss.c:
178        introduced '__bss_end'; assuming that __rtems_end
179        coincides with the end of .bss for the purpose of
180        zeroing .bss is very dangerous.
181
1822008-05-22      Joel Sherrill <joel.sherrill@OARcorp.com>
183
184        * shared/console/console.c: Fix typo.
185
1862008-05-22      Joel Sherrill <joel.sherrill@oarcorp.com>
187
188        * shared/console/console.c: Remove explicit switch and call
189        termios_baud_to_number().
190
1912008-05-15      Joel Sherrill <joel.sherrill@OARcorp.com>
192
193        * shared/startup/pretaskinghook.c: Add capability for bootcard.c BSP
194        Initialization Framework to ask the BSP where it has memory for the
195        RTEMS Workspace and C Program Heap. These collectively are referred
196        to as work area. If the BSP supports this, then it does not have to
197        include code to split the available memory between the two areas.
198        This reduces the amount of code in the BSP specific bspstart.c file.
199        Additionally, the shared framework can initialize the C Library, call
200        rtems_debug_enable(), and dirty the work area memory. Until most/all
201        BSPs support this new capability, if the BSP supports this, it should
202        call RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION from its configure.ac.
203        When the transition is complete, this autoconf macro can be removed.
204
2052008-05-12      Joel Sherrill <joel.sherrill@OARcorp.com>
206
207        * shared/startup/bspstart.c: Refactored and renamed initialization
208        routines to rtems_initialize_data_structures,
209        rtems_initialize_before_drivers, rtems_initialize_device_drivers, and
210        rtems_initialize_start_multitasking. This opened the sequence up so
211        that bootcard() could provide a more robust and flexible framework
212        which is easier to explain and understand. This also lays the
213        groundwork for sharing the division of available memory between the
214        RTEMS workspace and heap and the C library initialization across all
215        BSPs.
216
2172008-03-21      Till Straumann <strauman@slac.stanford.edu>
218
219        * shared/console/uart.c: In IRQ driven mode also
220        keep reading chars while they are available (fifo
221        could be enabled).
222
2232008-03-19      Till Straumann <strauman@slac.stanford.edu>
224
225        * shared/console/console.c, shared/console/uart.c,
226        shared/console/uart.h: added support for task-driven
227        console.
228
2292008-03-19      Till Straumann <strauman@slac.stanford.edu>
230
231        * shared/startup/pretaskinghook.c: install pointer
232        to rtems_malloc_sbrk_helpers_table. This (and derived)
233        BSPs rely on sbrk delivering even the first/initial
234        chunk of memory.
235
2362008-03-03      Joel Sherrill <joel.sherrill@OARcorp.com>
237
238        * shared/startup/linkcmds: Add wildcard to gcc_except_table section so
239        programs compiled with gcc 4.3.x can link.
240
2412008-02-19      Ralf Corsépius <ralf.corsepius@rtems.org>
242

244        * helas403: Remove (Abandoned).
245        * acinclude: Regenerate.
246
2472007-12-14      Joel Sherrill <joel.sherrill@oarcorp.com>
248
249        * acinclude.m4, gen5200/irq/irq.c, gen5200/startup/bspclean.c: Add
250        mvme3100.
251
2522007-12-11      Joel Sherrill <joel.sherrill@OARcorp.com>
253
254        * shared/startup/bspstart.c, shared/startup/pretaskinghook.c: Eliminate
255        copies of the Configuration Table. Use the RTEMS provided accessor
256        macros to obtain configuration fields.
257
2582007-12-10      Till Straumann <strauman@slac.stanford.edu>
259
260        * Makefile.am, start/preload.S: moved preload.S
261        to ../shared/start.
262
2632007-12-10      Till Straumann <strauman@slac.stanford.edu>
264
265        * shared/irq/irq_asm.S, shared/vectors/vectors.h:
266        renamed ASM_BOOKE_PIT_VECTOR to ASM_BOOKE_DEC_VECTOR
267        to be closer to 'official' nomenclature.
268
2692007-12-10      Till Straumann <strauman@slac.stanford.edu>
270
271        * shared/openpic/openpic.c: fixed wrong register
272        address in openpic_gettimer().
273
2742007-12-10      Till Straumann <strauman@slac.stanford.edu>
275
276        * shared/motorola/vpd.c, shared/motorola/vpd.h:
277        added code (originally developed for 'beatnik')
278        to read MotLoad VPD data from i2c eeprom.
279
2802007-12-10      Till Straumann <strauman@slac.stanford.edu>
281
282        * shared/vectors/README.deprecated, shared/irq/README.deprecated:
283        added READMEs stating that certain files should not be
284        copy/paste/modified when creating new BSPs. New BSPs
285        are encouraged to use the new library under
286        libcpu/powerpc/new-exceptions/bspsupport.
287
2882007-12-10      Till Straumann <strauman@slac.stanford.edu>
289       
290        * shared/vectors/vectors_entry.S, motorola_powerpc/bsp_specs,
291        shared/start/vectors_entry.S: moved vectors_entry.S to
292        'start' subdir and made a start file rather than
293        element of vectors.rel (it should always be linked but
294        won't if it is the sole member of vectors.rel).
295
2962007-12-08      Till Straumann <strauman@slac.stanford.edu>
297
298        * shared/vme/vme_universe.c: fixed wrong initialization
299        routine when using Tsi148 driver.
300
3012007-12-08      Till Straumann <strauman@slac.stanford.edu>
302
303        * Makefile.am: merged shared/vme/vme_universe.c and
304        shared/vme/vme_universe_dma.c into one file.
305        Added support for Tsi148 driver (DMA).
306
3072007-12-08      Till Straumann <strauman@slac.stanford.edu>
308
309        * shared/vme/VMEConfig.h, shared/vme/vme_universe.c:
310        added support for Tsi148 bridge; BSP can define which
311        bridge driver to use from VMEConfig.h.
312        Added 'err' macro parameter to BSP_VME_INSTALL_IRQ_MGR(err)
313        macro so that an error status can be passed back.
314
3152007-12-08      Till Straumann <strauman@slac.stanford.edu>
316
317        * irq_supp.h: was moved from shared/irq to
318        libcpu/powerpc/new-exceptions/bspsupport.
319
3202007-12-08      Till Straumann <strauman@slac.stanford.edu>

323        mbx8xx/irq/irq.c, mpc8260ads/irq/irq.c, mvme5500/irq/irq.c,
324        psim/irq/no_pic.c, score603e/irq/irq.c, shared/irq/irq_supp.h,
325        shared/irq/openpic_i8259_irq.c, virtex/irq/irq_init.c:
326        let C_dispatch_irq_handler() return zero to indicate to
327        low-level exception handling code that the exception
328        was handled (not used yet).
329
3302007-12-08      Till Straumann <strauman@slac.stanford.edu>
331
332        *shared/irq/irq_supp.h: removed cpp test for
333        BSP_SHARED_HANDLER_SUPPORT; BSPs using irq_supp.h
334        *must* implement shared handlers.
335
3362007-12-06      Till Straumann <strauman@slac.stanford.edu>
337
338        * shared/openpic/openpic.c, shared/openpic/openpic.h:
339        added routines to set timer period and interupt mask
340        and to read current count.
341
3422007-12-06      Till Straumann <strauman@slac.stanford.edu>
343
344        * virtex/irq/irq_init.c: use new ASM_xxx_VECTOR names.

3462007-12-06      Till Straumann <strauman@slac.stanford.edu>
347
348        * shared/vectors/vectors_init.c: replaced
349        switch ( current_ppc_cpu ) { } check by feature check.
350
3512007-12-06      Till Straumann <strauman@slac.stanford.edu>
352
353        * shared/irq/irq_asm.S, shared/vectors/vectors.S:
354        Replaced use of hardcoded PPC_EXC_MSR_BITS by a
355        run-time method to determine these bits (use settings
356        effective before exception occurred).
357        Replaced use of hardcoded ASM_VECTORS_CRITICAL by
358        'bsp_raw_vector_is_405_critical' variable.
359
3602007-12-05      Till Straumann <strauman@slac.stanford.edu>
361
362        * shared/irq/irq_supp.h: removed stray '*/'. Removed
363        inclusion of <stdlib.h> which is unnecessary and broke
364        if_dc in an obscure way (due to malloc/free redefinition
365        in the networking code).
366
3672007-12-05      Till Straumann <strauman@slac.stanford.edu>
368
369        * shared/irq/irq_asm.S, shared/vectors/vectors.S,
370        shared/vectors/vectors.h, shared/vectors/vectors_init.c:
371        Converted exception vector names to new ones
372        (qualified by <cpu_type> if non-std ppc exceptions).
373
374
3752007-12-04      Till Straumann <strauman@slac.stanford.edu>
376
377        * shared/startup/bspstart.c: export BSP_commandline_string
378        variable.
379
3802007-12-04      Till Straumann <strauman@slac.stanford.edu>
381
382        * shared/flash/flash.c: added lazy init of driver
383        from BSP_flashWriteFile().
384
3852007-12-04      Joel Sherrill <joel.sherrill@OARcorp.com>
386
387        * shared/startup/bspstart.c: Move interrupt_stack_size field from CPU
388        Table to Configuration Table. Eliminate CPU Table from all ports.
389        Delete references to CPU Table in all forms.
390
3912007-12-03      Joel Sherrill <joel.sherrill@oarcorp.com>
392
393        * shared/irq/irq.c: Spacing.
394
3952007-12-03      Joel Sherrill <joel.sherrill@OARcorp.com>
396
397        * shared/startup/bspstart.c: Moved most of the remaining CPU Table
398        fields to the Configuration Table. This included pretasking_hook,
399        predriver_hook, postdriver_hook, idle_task, do_zero_of_workspace,
400        extra_mpci_receive_server_stack, stack_allocate_hook, and
401        stack_free_hook. As a side-effect of this effort some multiprocessing
402        code was made conditional and some style clean up occurred.
403
4042007-12-03      Joel Sherrill <joel.sherrill@oarcorp.com>
405
406        * shared/irq/irq.c, shared/irq/irq_supp.h: Correct conditionals and
407        includes.
408
4092007-12-02      Till Straumann <strauman@slac.stanford.edu>
410
411        * shared/irq/i8259.c, shared/irq/irq.h, shared/irq/irq_supp.h,
412        shared/irq/openpic_i8259_irq.c: BSP_disable_irq_at_pic(),
413        openpic_disable_irq(), BSP_irq_disable_at_i8259s() now return
414        0/1 if irq was disabled/enabled prior to disabling.
415        irq_supp.h now exports a inline helper routine for scanning
416        a list of shared handlers; to be used by PIC drivers.
417
4182007-12-02      Till Straumann <strauman@slac.stanford.edu>
419
420        * shared/openpic/openpic.c shared/openpic/openpic.h,
421        shared/irq/irq_init.c: added more parameters to
422        openpic_init() so that more details of the configuration
423        can be overridden/set from the BSP. Moved setup of
424        the EPIC-specific EOI delay from BSP code into openpic_init()
425        using the new 'epic_freq' parameter.
426
4272007-12-02      Till Straumann <strauman@slac.stanford.edu>
428        * shared/openpic/openpic.c, shared/openpic/openpic.h:
429        - eliminated conditional compilation (#ifdef mpc8240)
430          The difference in register-layout between the EPIC
431          and the std. openPIC is handled by an offset parameter
432          which can be set at run-time (initialization) with
433          a new routine 'openpic_set_src_offset()'.
434        - allow BSP to define symbol BSP_OPEN_PIC_BIG_ENDIAN
435          which builds the driver for big-endian register access
436          (mpc8540).
437        - openpic_disable_irq() now returns the old state so
438          that it can be restored later.
439
4402007-12-01      Till Straumann <strauman@slac.stanford.edu>
441
442        * shared/irq/openpic_i8259_irq.c:
443        - conditionally define 'irq_mask_or_tbl' only if
444          BSP_PCI_ISA_BRIDGE_IRQ is defined.
445        - use _ISR_Get_level() / _ISR_Set_level() for re-enabling
446          interrupts rather than messing with MSR directly;
447          these macros:
448            o implement compiler memory barrier
449                o will handle multiple levels (e500 'critical' interrupts)
450                  if they are ever supported.
451        - decrementer irqs are also shareable - added list traversal.
452
4532007-12-01      Till Straumann <strauman@slac.stanford.edu>
454
455        * shared/irq/irq_supp.h: Make sure BSP_SHARED_HANDLER_SUPPORT
456        is set. The shared irq manager supports shared interrupts
457        (but requires also that the PIC-driver supports them by
458        traversing the list of shared handlers).
459        Declare C_dispatch_irq_handler() which must be defined
460        (like the other routines declared in this header) by the
461        PIC-driver.
462
4632007-12-01      Till Straumann <strauman@slac.stanford.edu>
464
465        * shared/clock/p_clock.c: (run-time) check for e500-cpu
466        and install different ISR for that type of CPU.
467
4682007-12-01      Till Straumann <strauman@slac.stanford.edu>
469
470        * shared/pci/detect_raven_bridge.c: use ifdef mvme2100
471        rather than ifdef mpc824x so that we don't depend on
472        compile-time CPU flavor. Eventually, this should become
473        a run-time check.
474
4752007-12-01      Till Straumann <strauman@slac.stanford.edu>
476
477        * shared/vectors/vectors.h: Give the BSP_Exception_frame

479
4802007-12-01      Till Straumann <strauman@slac.stanford.edu>
481
482        * shared/vme/vmeconfig.c: Include <libcpu/bat.h> only
483        if the BSP-specific configuration header (VMEConfig.h)
484        defines BSP_VME_BAT_IDX so that this file can be used
485        on CPUs w/o bats (e500).
486
4872007-11-30      Till Straumann <strauman@slac.stanford.edu>
488

490
4912007-11-30      Till Straumann <strauman@slac.stanford.edu>
492
493        * shared/startup/pretaskinghook.c: Replaced inclusion of
494        <bsp/consoleIo.h> by <rtems/bspIo.> (for printk) and
495        made it conditional on #ifdef SHOW_MORE_INIT_SETTINGS.
496
4972007-11-30      Till Straumann <strauman@slac.stanford.edu>
498
499        * shared/startup/bspstart.c: Removed excess /*, replaced
500        #ifdef checks for mpc8240 by #ifdef mvme2100; eventually
501        there should be run-time checks.
502
5032007-11-30      Till Straumann <strauman@slac.stanford.edu>
504
505        * shared/motorola/motorola.c: removed excess initializer
506        elements.
507
5082007-11-30      Till Straumann <strauman@slac.stanford.edu>
509
510        * shared/irq/irq.h, shared/irq/irq.c, shared/irq/irq_init.c,
511        shared/irq/irq_supp.h (added):
512        Removed 'is_processor_irq()' from irq.c; the BSP routines
513        BSP_enable_irq_at_pic()/BSP_disable_irq_at_pic() are required
514        to ignore processor irqs anyways. Removed
515        all BSP-defined constants from irq.c. This makes irq.c (almost)
516        binary-compatible among BSPs (ultimate goal is making 'shared'
517        a library).
518        Added a header (irq_supp.h) defining the interface between
519        the generic interrupt manager (irq.c) and the routines it
520        requires to be supplied by the BSP (eventually, these
521        should go into rtems/irq.h).
522
5232007-11-30      Till Straumann <strauman@slac.stanford.edu>
524
525        * shared/irq/irq.h, shared/irq/irq_init.c: Removed the definition
526        of ASM_IRQ_VECTOR_BASE; this symbol was only use to
527        initialize the irqBase member of the rtems_irq_global_settings
528        struct. However, irqBase is an rtems_irq_symbolic_name,
529        so using BSP_LOWEST_OFFSET is more appropriate.
530
5312007-11-28      Joel Sherrill <joel.sherrill@OARcorp.com>
532
533        * shared/startup/bspstart.c: Eliminate PowerPC specific elements from
534        the CPU Table. They have been replaced with variables named bsp_XXX
535        as needed.
536
5372007-11-29      Till Straumann <strauman@slac.stanford.edu>
538
539        * Makefile.am, shared/flash, shared/flash/flash.c,
540        shared/flash/flashPgm.h, shared/flash/flashPgmPvt.h,
541        shared/flash/intelFlash.c, shared/flash/spansionFlash.c:
542        Added flash programmer API, implementation and chip drivers
543        for some intel + spansion flash chips (as found on mvme5500,
544        mvme6100 and mvme3100 boards).
545        A more appopriate place would probably be libchip but
546        I don't know if the API is acceptable and if the implementation
547        is generic enough (e.g., no CFI support) so I leave it here
548        for now.
549
5502007-11-26      Joel Sherrill <joel.sherrill@OARcorp.com>
551
552        * shared/console/uart.c: Fix typo and spacing.
553
5542007-11-21      Till Straumann <strauman@slac.stanford.edu>
555
556        * shared/console/uart.c: when draining UART during
557        initialization (wait for possible printk() activity
558        to finish) look at TEMT (fifo, holding-reg and shift-reg)
559        rather than THRE (fifo, holding-reg only). This resolved
560        some scrambled output issues for me.
561
562        Enhanced semantics: if BSP initializes BSPBaseBaud to a negative
563        value then the driver interprets the modulus as a speed value
564        and uses the current setting of the divisor to compute the
565        clock speed (BSPBaseBaud). This is useful if you have a board
566        that you know is initialized e.g., to 9600 but you
567        don't know the clock speed.

597        PR 1257/bsps
598        * shared/irq/i8259.c, shared/irq/irq.c: Code outside of cpukit should
599        use the public API for
600        rtems_interrupt_disable/rtems_interrupt_enable. By bypassing the
601        public API and directly accessing _CPU_ISR_Disable and
602        _CPU_ISR_Enable, they were bypassing the compiler memory barrier
603        directive which could lead to problems. This patch also changes the

1419        shared/vectors/vectors.h, shared/vectors/vectors_init.c: Per PR216,
1420        "libbsp/powerpc/shared" BSP has been modified considerably with the
1421        goal to make it more flexible and reusable by other BSPs. The main
1422        strategies were: - eliminate hardcoded base addresses; devices use
1423        offsets and a BSP defined base address. - separate functionality
1424        into different files (e.g. reboot from inch.c to reboot.c) which can
1425        be overridden by a 'derived' BSP. - separate initialization code
1426        into separate files (e.g.  PCI bridge detection/initialization was
1427        separated from the more generic PCI access routines), also to make
1428        it easier for 'derived' BSPs to substitute their own initialization
1429        code. There are also a couple of enhancements and fixes: - IRQ
1430        handling code now has a hook for attaching a VME bridge. - OpenPIC
1431        is now explicitely initialized (polarities, senses). Eliminated the
1432        implicit assumption on the presence of an ISA PIC. - UART and
1433        console driver now supports more than 1 port. The current maximum of
1434        2 can easily be extended by enlarging a table (it would even be
1435        easier if the ISR API was not broken by design). - fixed polled_io.c
1436        so it correctly supports console on COM2 - fixed TLB invalidation
1437        code (start.S). - exception handler prints a stack backtrace. -
1438        added BSP_pciFindDevice() to scan the pci bus for a particular
1439        vendor/device/instance.
