14        * shared/startup/bspgetworkarea.c: Switch from ssize_t to uintptr_t for
15        bsp_get_work_area() since the work area is larger than a single
16        allocatable object.

29        * shared/irq/irq_asm.S: When the type rtems_boolean was switched to the
30        C99 bool, the size changed from 4 bytes to 1 byte. The interrupt
31        dispatching code accesses two boolean variables for scheduling
32        purposes and the assembly implementations of this code did not get
33        updated.

86        which would limit the work area to 64K.

91        bsp_cleanup() which can optionally print a message, poll for user to

93        bsp_cleanup() implementations which had their own implementation and

107        which reflect those tested on psim. Hopefully they work on all
108        boards. The initialization stack is explicitly declared in the
109        linkcmds memory layout rather than magic math.

123        of bsp_get_work_area() in its own file and rely on BSP Framework to
124        perform more initialization.

1462008-09-05      Joel Sherrill <joel.sherrill@OARcorp.com>
147
148        * shared/clock/clock.c: The Shared Memory Driver no longer requires the
149        special IOCTL in Clock_control. This was a hack which has existed
150        since before the Classic API Timer Manager was implemented. All
151        implementations of and references to Clock_control were removed.

189        mvme5500/startup/bspstart.c, psim/startup/bspstart.c,
190        shared/startup/bspstart.c: The usage of SPRG0 as changed.  It is now
191        used to store the interrupt disable mask.  See bootcard.c and
192        ppc_exc_initialize() for default initialization.
193
194        Update to new exception initialization routine ppc_exc_initialize().
195        The exception low level code has changed, see libcpu/powerpc/ChangeLog.
196

198        mpc8260ads/startup/bspstart.c, ss555/startup/bspstart.c,
199        virtex/startup/bspstart.c: The usage of SPRG0 as changed.  It is now
200        used to store the interrupt disable mask.  See bootcard.c for default
201        initialization.

206        operands.
207
2082008-07-09      Sebastian Huber <sebastian.huber@embedded-brains.de>
209
210        * shared/clock/clock.c: Alternative clock driver.  Uses exception handler
211        directly.  Supports special variants for Book E and e300 cores.  For
212        standard decrementer CPUs the new decrementer value is calculated with
213        reference to a time base so that a time drift is avoided.
214
2152008-07-01      Joel Sherrill <joel.sherrill@oarcorp.com>
216
217        * shared/uboot_getenv.c: New file.
218
2192008-06-02      Joel Sherrill <joel.sherrill@oarcorp.com>
220
221        * shared/startup/panic.c: Convention calls for leading underscore on
222        private RTEMS variables.
223
2242008-05-23      Till Straumann <strauman@slac.stanford.edu>
225
226        * shared/startup/pretaskinghook.c: removed declaration
227        of BSP_vme_config() (which is already declared in
228        <bsp/VME.h>. Removed test for NULL-ness of BSP_vme_config;
229        gcc doesn't seem to understand that the linker may
230        define this to be NULL... Silences a compiler warning
231        (and users can always provide an empty routine).
232
2332008-05-22      Till Straumann <strauman@slac.stanford.edu>
234
235        * shared/startup/linkcmds, shared/startup/zerobss.c:
236        introduced '__bss_end'; assuming that __rtems_end
237        coincides with the end of .bss for the purpose of
238        zeroing .bss is very dangerous.
239
2402008-05-22      Joel Sherrill <joel.sherrill@OARcorp.com>
241
242        * shared/console/console.c: Fix typo.
243
2442008-05-22      Joel Sherrill <joel.sherrill@oarcorp.com>
245
246        * shared/console/console.c: Remove explicit switch and call
247        termios_baud_to_number().
248
2492008-05-15      Joel Sherrill <joel.sherrill@OARcorp.com>
250
251        * shared/startup/pretaskinghook.c: Add capability for bootcard.c BSP
252        Initialization Framework to ask the BSP where it has memory for the
253        RTEMS Workspace and C Program Heap. These collectively are referred
254        to as work area. If the BSP supports this, then it does not have to
255        include code to split the available memory between the two areas.
256        This reduces the amount of code in the BSP specific bspstart.c file.
257        Additionally, the shared framework can initialize the C Library, call
258        rtems_debug_enable(), and dirty the work area memory. Until most/all
259        BSPs support this new capability, if the BSP supports this, it should
260        call RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION from its configure.ac.
261        When the transition is complete, this autoconf macro can be removed.
262
2632008-05-12      Joel Sherrill <joel.sherrill@OARcorp.com>
264
265        * shared/startup/bspstart.c: Refactored and renamed initialization
266        routines to rtems_initialize_data_structures,
267        rtems_initialize_before_drivers, rtems_initialize_device_drivers, and
268        rtems_initialize_start_multitasking. This opened the sequence up so
269        that bootcard() could provide a more robust and flexible framework
270        which is easier to explain and understand. This also lays the
271        groundwork for sharing the division of available memory between the
272        RTEMS workspace and heap and the C library initialization across all
273        BSPs.
274
2752008-03-21      Till Straumann <strauman@slac.stanford.edu>
276
277        * shared/console/uart.c: In IRQ driven mode also
278        keep reading chars while they are available (fifo
279        could be enabled).
280
2812008-03-19      Till Straumann <strauman@slac.stanford.edu>
282
283        * shared/console/console.c, shared/console/uart.c,
284        shared/console/uart.h: added support for task-driven
285        console.
286
2872008-03-19      Till Straumann <strauman@slac.stanford.edu>
288
289        * shared/startup/pretaskinghook.c: install pointer
290        to rtems_malloc_sbrk_helpers_table. This (and derived)
291        BSPs rely on sbrk delivering even the first/initial
292        chunk of memory.
293
2942008-03-03      Joel Sherrill <joel.sherrill@OARcorp.com>
295
296        * shared/startup/linkcmds: Add wildcard to gcc_except_table section so
297        programs compiled with gcc 4.3.x can link.
298
2992008-02-19      Ralf Corsépius <ralf.corsepius@rtems.org>

303        * acinclude: Regenerate.
304
3052007-12-14      Joel Sherrill <joel.sherrill@oarcorp.com>
306
307        * acinclude.m4, gen5200/irq/irq.c, gen5200/startup/bspclean.c: Add
308        mvme3100.
309
3102007-12-11      Joel Sherrill <joel.sherrill@OARcorp.com>
311
312        * shared/startup/bspstart.c, shared/startup/pretaskinghook.c: Eliminate
313        copies of the Configuration Table. Use the RTEMS provided accessor
314        macros to obtain configuration fields.
315
3162007-12-10      Till Straumann <strauman@slac.stanford.edu>
317
318        * Makefile.am, start/preload.S: moved preload.S
319        to ../shared/start.
320
3212007-12-10      Till Straumann <strauman@slac.stanford.edu>
322
323        * shared/irq/irq_asm.S, shared/vectors/vectors.h:
324        renamed ASM_BOOKE_PIT_VECTOR to ASM_BOOKE_DEC_VECTOR
325        to be closer to 'official' nomenclature.
326
3272007-12-10      Till Straumann <strauman@slac.stanford.edu>
328
329        * shared/openpic/openpic.c: fixed wrong register
330        address in openpic_gettimer().
331

333
334        * shared/motorola/vpd.c, shared/motorola/vpd.h:
335        added code (originally developed for 'beatnik')
336        to read MotLoad VPD data from i2c eeprom.
337
3382007-12-10      Till Straumann <strauman@slac.stanford.edu>
339
340        * shared/vectors/README.deprecated, shared/irq/README.deprecated:
341        added READMEs stating that certain files should not be
342        copy/paste/modified when creating new BSPs. New BSPs
343        are encouraged to use the new library under
344        libcpu/powerpc/new-exceptions/bspsupport.
345
3462007-12-10      Till Straumann <strauman@slac.stanford.edu>
347       
348        * shared/vectors/vectors_entry.S, motorola_powerpc/bsp_specs,
349        shared/start/vectors_entry.S: moved vectors_entry.S to
350        'start' subdir and made a start file rather than
351        element of vectors.rel (it should always be linked but
352        won't if it is the sole member of vectors.rel).

3542007-12-08      Till Straumann <strauman@slac.stanford.edu>
355
356        * shared/vme/vme_universe.c: fixed wrong initialization
357        routine when using Tsi148 driver.
358
3592007-12-08      Till Straumann <strauman@slac.stanford.edu>
360
361        * Makefile.am: merged shared/vme/vme_universe.c and
362        shared/vme/vme_universe_dma.c into one file.
363        Added support for Tsi148 driver (DMA).
364
3652007-12-08      Till Straumann <strauman@slac.stanford.edu>
366
367        * shared/vme/VMEConfig.h, shared/vme/vme_universe.c:
368        added support for Tsi148 bridge; BSP can define which
369        bridge driver to use from VMEConfig.h.
370        Added 'err' macro parameter to BSP_VME_INSTALL_IRQ_MGR(err)
371        macro so that an error status can be passed back.
372
3732007-12-08      Till Straumann <strauman@slac.stanford.edu>
374
375        * irq_supp.h: was moved from shared/irq to

383        shared/irq/openpic_i8259_irq.c, virtex/irq/irq_init.c:
384        let C_dispatch_irq_handler() return zero to indicate to
385        low-level exception handling code that the exception
386        was handled (not used yet).
387
3882007-12-08      Till Straumann <strauman@slac.stanford.edu>
389
390        *shared/irq/irq_supp.h: removed cpp test for
391        BSP_SHARED_HANDLER_SUPPORT; BSPs using irq_supp.h
392        *must* implement shared handlers.
393
3942007-12-06      Till Straumann <strauman@slac.stanford.edu>
395
396        * shared/openpic/openpic.c, shared/openpic/openpic.h:

454

457        predriver_hook, postdriver_hook, idle_task, do_zero_of_workspace,
458        extra_mpci_receive_server_stack, stack_allocate_hook, and
459        stack_free_hook. As a side-effect of this effort some multiprocessing
460        code was made conditional and some style clean up occurred.

471        openpic_disable_irq(), BSP_irq_disable_at_i8259s() now return
472        0/1 if irq was disabled/enabled prior to disabling.

477
478        * shared/openpic/openpic.c shared/openpic/openpic.h,
479        shared/irq/irq_init.c: added more parameters to
480        openpic_init() so that more details of the configuration
481        can be overridden/set from the BSP. Moved setup of
482        the EPIC-specific EOI delay from BSP code into openpic_init()
483        using the new 'epic_freq' parameter.
484
4852007-12-02      Till Straumann <strauman@slac.stanford.edu>
486        * shared/openpic/openpic.c, shared/openpic/openpic.h:
487        - eliminated conditional compilation (#ifdef mpc8240)
488          The difference in register-layout between the EPIC
489          and the std. openPIC is handled by an offset parameter
490          which can be set at run-time (initialization) with
491          a new routine 'openpic_set_src_offset()'.
492        - allow BSP to define symbol BSP_OPEN_PIC_BIG_ENDIAN
493          which builds the driver for big-endian register access
494          (mpc8540).
495        - openpic_disable_irq() now returns the old state so
496          that it can be restored later.

501        - conditionally define 'irq_mask_or_tbl' only if
502          BSP_PCI_ISA_BRIDGE_IRQ is defined.
503        - use _ISR_Get_level() / _ISR_Set_level() for re-enabling
504          interrupts rather than messing with MSR directly;
505          these macros:
506            o implement compiler memory barrier
507                o will handle multiple levels (e500 'critical' interrupts)
508                  if they are ever supported.
509        - decrementer irqs are also shareable - added list traversal.
510
5112007-12-01      Till Straumann <strauman@slac.stanford.edu>
512
513        * shared/irq/irq_supp.h: Make sure BSP_SHARED_HANDLER_SUPPORT
514        is set. The shared irq manager supports shared interrupts
515        (but requires also that the PIC-driver supports them by
516        traversing the list of shared handlers).
517        Declare C_dispatch_irq_handler() which must be defined
518        (like the other routines declared in this header) by the
519        PIC-driver.
520
5212007-12-01      Till Straumann <strauman@slac.stanford.edu>

5262007-12-01      Till Straumann <strauman@slac.stanford.edu>
527

529        rather than ifdef mpc824x so that we don't depend on
530        compile-time CPU flavor. Eventually, this should become
531        a run-time check.

541        if the BSP-specific configuration header (VMEConfig.h)
542        defines BSP_VME_BAT_IDX so that this file can be used
543        on CPUs w/o bats (e500).

554
5552007-11-30      Till Straumann <strauman@slac.stanford.edu>
556
557        * shared/startup/bspstart.c: Removed excess /*, replaced

559        there should be run-time checks.
560
5612007-11-30      Till Straumann <strauman@slac.stanford.edu>
562

567
568        * shared/irq/irq.h, shared/irq/irq.c, shared/irq/irq_init.c,
569        shared/irq/irq_supp.h (added):
570        Removed 'is_processor_irq()' from irq.c; the BSP routines
571        BSP_enable_irq_at_pic()/BSP_disable_irq_at_pic() are required
572        to ignore processor irqs anyways. Removed
573        all BSP-defined constants from irq.c. This makes irq.c (almost)
574        binary-compatible among BSPs (ultimate goal is making 'shared'
575        a library).
576        Added a header (irq_supp.h) defining the interface between
577        the generic interrupt manager (irq.c) and the routines it
578        requires to be supplied by the BSP (eventually, these
579        should go into rtems/irq.h).
580
5812007-11-30      Till Straumann <strauman@slac.stanford.edu>
582
583        * shared/irq/irq.h, shared/irq/irq_init.c: Removed the definition
584        of ASM_IRQ_VECTOR_BASE; this symbol was only use to
585        initialize the irqBase member of the rtems_irq_global_settings
586        struct. However, irqBase is an rtems_irq_symbolic_name,
587        so using BSP_LOWEST_OFFSET is more appropriate.
588
5892007-11-28      Joel Sherrill <joel.sherrill@OARcorp.com>
590
591        * shared/startup/bspstart.c: Eliminate PowerPC specific elements from
592        the CPU Table. They have been replaced with variables named bsp_XXX
593        as needed.
594

598        shared/flash/flashPgm.h, shared/flash/flashPgmPvt.h,
599        shared/flash/intelFlash.c, shared/flash/spansionFlash.c:
600        Added flash programmer API, implementation and chip drivers
601        for some intel + spansion flash chips (as found on mvme5500,
602        mvme6100 and mvme3100 boards).
603        A more appopriate place would probably be libchip but
604        I don't know if the API is acceptable and if the implementation
605        is generic enough (e.g., no CFI support) so I leave it here
606        for now.

613
614        * shared/console/uart.c: when draining UART during
615        initialization (wait for possible printk() activity
616        to finish) look at TEMT (fifo, holding-reg and shift-reg)
617        rather than THRE (fifo, holding-reg only). This resolved
618        some scrambled output issues for me.
619
620        Enhanced semantics: if BSP initializes BSPBaseBaud to a negative
621        value then the driver interprets the modulus as a speed value
622        and uses the current setting of the divisor to compute the
623        clock speed (BSPBaseBaud). This is useful if you have a board
624        that you know is initialized e.g., to 9600 but you
625        don't know the clock speed.

1199        Unfortunately, the supported 'printk' format string subset of the
1200        polled-io and libcpu implementations are different - hence, a few
1201        format strings in the ppc/shared BSP were changed.
1202        * shared/console/uart.c, shared/console/uart.h:
1203        BSP_output_char_via_serial() prototype changed to match the
1204        BSP_output_char_function_type.  Note that the motorola BSPs use
1205        polled-io for the output_char routine, not the uart.c version. The
1206        latter can be used be other BSPs however (e.g. SVGM).
1207        * shared/console/polled_io.c: libcpu provides 'printk' already.
1208        Therefore, the implementation in this file was removed (still used
1209        for the bootloader, though).  It now provides BSP_output_char() for
1210        libcpu's printk().

1478        "libbsp/powerpc/shared" BSP has been modified considerably with the
1479        goal to make it more flexible and reusable by other BSPs. The main
1480        strategies were: - eliminate hardcoded base addresses; devices use
1481        offsets and a BSP defined base address. - separate functionality
1482        into different files (e.g. reboot from inch.c to reboot.c) which can
1483        be overridden by a 'derived' BSP. - separate initialization code
1484        into separate files (e.g.  PCI bridge detection/initialization was
1485        separated from the more generic PCI access routines), also to make
1486        it easier for 'derived' BSPs to substitute their own initialization
1487        code. There are also a couple of enhancements and fixes: - IRQ
1488        handling code now has a hook for attaching a VME bridge. - OpenPIC
1489        is now explicitely initialized (polarities, senses). Eliminated the
1490        implicit assumption on the presence of an ISA PIC. - UART and
1491        console driver now supports more than 1 port. The current maximum of
1492        2 can easily be extended by enlarging a table (it would even be
1493        easier if the ISR API was not broken by design). - fixed polled_io.c
1494        so it correctly supports console on COM2 - fixed TLB invalidation
1495        code (start.S). - exception handler prints a stack backtrace. -
1496        added BSP_pciFindDevice() to scan the pci bus for a particular
1497        vendor/device/instance.
