2
3        * shared/clock/clock.c: Update due to powerpc-utilty.h changes.
4
52008-07-14      Sebastian Huber <sebastian.huber@embedded-brains.de>
6
7        * mpc55xxevb: New BSP.
8
92008-07-14      Thomas Doefler <Thomas.Doerfler@embedded-brains.de>
10        * haleakala: added new BSP
11
122008-07-11      Sebastian Huber <sebastian.huber@embedded-brains.de>
13
14        * ep1a/startup/bspstart.c, mvme3100/startup/bspstart.c,
15        mvme5500/startup/bspstart.c, psim/startup/bspstart.c,
16        shared/startup/bspstart.c: The usage of SPRG0 as changed.  It is now
17        used to store the interrupt disable mask.  See bootcard.c and
18        ppc_exc_initialize() for default initialization.
19
20        Update to new exception initialization routine ppc_exc_initialize().
21        The exception low level code has changed, see libcpu/powerpc/ChangeLog.
22
23        * gen5200/startup/bspstart.c, mbx8xx/startup/bspstart.c,
24        mpc8260ads/startup/bspstart.c, ss555/startup/bspstart.c,
25        virtex/startup/bspstart.c: The usage of SPRG0 as changed.  It is now
26        used to store the interrupt disable mask.  See bootcard.c for default
27        initialization.
28
292008-07-10      Till Straumann <strauman@slac.stanford.edu>
30
31        * shared/flash/spansionFlash.c: removed "m" memory
32        operands.
33
342008-07-09      Sebastian Huber <sebastian.huber@embedded-brains.de>
35
36        * shared/clock/clock.c: Alternative clock driver.  Uses exception handler
37        directly.  Supports special variants for Book E and e300 cores.  For
38        standard decrementer CPUs the new decrementer value is calculated with
39        reference to a time base so that a time drift is avoided.
40
412008-07-01      Joel Sherrill <joel.sherrill@oarcorp.com>
42
43        * shared/uboot_getenv.c: New file.
44
452008-06-02      Joel Sherrill <joel.sherrill@oarcorp.com>
46
47        * shared/startup/panic.c: Convention calls for leading underscore on
48        private RTEMS variables.
49
502008-05-23      Till Straumann <strauman@slac.stanford.edu>
51
52        * shared/startup/pretaskinghook.c: removed declaration
53        of BSP_vme_config() (which is already declared in
54        <bsp/VME.h>. Removed test for NULL-ness of BSP_vme_config;
55        gcc doesn't seem to understand that the linker may
56        define this to be NULL... Silences a compiler warning
57        (and users can always provide an empty routine).
58
592008-05-22      Till Straumann <strauman@slac.stanford.edu>
60
61        * shared/startup/linkcmds, shared/startup/zerobss.c:
62        introduced '__bss_end'; assuming that __rtems_end
63        coincides with the end of .bss for the purpose of
64        zeroing .bss is very dangerous.
65
662008-05-22      Joel Sherrill <joel.sherrill@OARcorp.com>
67
68        * shared/console/console.c: Fix typo.
69
702008-05-22      Joel Sherrill <joel.sherrill@oarcorp.com>
71
72        * shared/console/console.c: Remove explicit switch and call
73        termios_baud_to_number().
74
752008-05-15      Joel Sherrill <joel.sherrill@OARcorp.com>
76
77        * shared/startup/pretaskinghook.c: Add capability for bootcard.c BSP
78        Initialization Framework to ask the BSP where it has memory for the
79        RTEMS Workspace and C Program Heap. These collectively are referred
80        to as work area. If the BSP supports this, then it does not have to
81        include code to split the available memory between the two areas.
82        This reduces the amount of code in the BSP specific bspstart.c file.
83        Additionally, the shared framework can initialize the C Library, call
84        rtems_debug_enable(), and dirty the work area memory. Until most/all
85        BSPs support this new capability, if the BSP supports this, it should
86        call RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION from its configure.ac.
87        When the transition is complete, this autoconf macro can be removed.
88
892008-05-12      Joel Sherrill <joel.sherrill@OARcorp.com>
90
91        * shared/startup/bspstart.c: Refactored and renamed initialization
92        routines to rtems_initialize_data_structures,
93        rtems_initialize_before_drivers, rtems_initialize_device_drivers, and
94        rtems_initialize_start_multitasking. This opened the sequence up so
95        that bootcard() could provide a more robust and flexible framework
96        which is easier to explain and understand. This also lays the
97        groundwork for sharing the division of available memory between the
98        RTEMS workspace and heap and the C library initialization across all
99        BSPs.
100
1012008-03-21      Till Straumann <strauman@slac.stanford.edu>
102
103        * shared/console/uart.c: In IRQ driven mode also
104        keep reading chars while they are available (fifo
105        could be enabled).
106
1072008-03-19      Till Straumann <strauman@slac.stanford.edu>
108
109        * shared/console/console.c, shared/console/uart.c,
110        shared/console/uart.h: added support for task-driven
111        console.
112
1132008-03-19      Till Straumann <strauman@slac.stanford.edu>
114
115        * shared/startup/pretaskinghook.c: install pointer
116        to rtems_malloc_sbrk_helpers_table. This (and derived)
117        BSPs rely on sbrk delivering even the first/initial
118        chunk of memory.
119
1202008-03-03      Joel Sherrill <joel.sherrill@OARcorp.com>
121
122        * shared/startup/linkcmds: Add wildcard to gcc_except_table section so
123        programs compiled with gcc 4.3.x can link.
124
1252008-02-19      Ralf Corsépius <ralf.corsepius@rtems.org>
126
127        * gen405: Remove (Abandoned).
128        * helas403: Remove (Abandoned).
129        * acinclude: Regenerate.
130
1312007-12-14      Joel Sherrill <joel.sherrill@oarcorp.com>
132
133        * acinclude.m4, gen5200/irq/irq.c, gen5200/startup/bspclean.c: Add
134        mvme3100.
135
1362007-12-11      Joel Sherrill <joel.sherrill@OARcorp.com>
137
138        * shared/startup/bspstart.c, shared/startup/pretaskinghook.c: Eliminate
139        copies of the Configuration Table. Use the RTEMS provided accessor
140        macros to obtain configuration fields.
141
1422007-12-10      Till Straumann <strauman@slac.stanford.edu>
143
144        * Makefile.am, start/preload.S: moved preload.S
145        to ../shared/start.
146
1472007-12-10      Till Straumann <strauman@slac.stanford.edu>
148
149        * shared/irq/irq_asm.S, shared/vectors/vectors.h:
150        renamed ASM_BOOKE_PIT_VECTOR to ASM_BOOKE_DEC_VECTOR
151        to be closer to 'official' nomenclature.
152
1532007-12-10      Till Straumann <strauman@slac.stanford.edu>
154
155        * shared/openpic/openpic.c: fixed wrong register
156        address in openpic_gettimer().
157
1582007-12-10      Till Straumann <strauman@slac.stanford.edu>
159
160        * shared/motorola/vpd.c, shared/motorola/vpd.h:
161        added code (originally developed for 'beatnik')
162        to read MotLoad VPD data from i2c eeprom.
163
1642007-12-10      Till Straumann <strauman@slac.stanford.edu>
165
166        * shared/vectors/README.deprecated, shared/irq/README.deprecated:
167        added READMEs stating that certain files should not be
168        copy/paste/modified when creating new BSPs. New BSPs
169        are encouraged to use the new library under
170        libcpu/powerpc/new-exceptions/bspsupport.
171
1722007-12-10      Till Straumann <strauman@slac.stanford.edu>
173       
174        * shared/vectors/vectors_entry.S, motorola_powerpc/bsp_specs,
175        shared/start/vectors_entry.S: moved vectors_entry.S to
176        'start' subdir and made a start file rather than
177        element of vectors.rel (it should always be linked but
178        won't if it is the sole member of vectors.rel).
179
1802007-12-08      Till Straumann <strauman@slac.stanford.edu>
181
182        * shared/vme/vme_universe.c: fixed wrong initialization
183        routine when using Tsi148 driver.
184
1852007-12-08      Till Straumann <strauman@slac.stanford.edu>
186
187        * Makefile.am: merged shared/vme/vme_universe.c and
188        shared/vme/vme_universe_dma.c into one file.
189        Added support for Tsi148 driver (DMA).
190
1912007-12-08      Till Straumann <strauman@slac.stanford.edu>
192
193        * shared/vme/VMEConfig.h, shared/vme/vme_universe.c:
194        added support for Tsi148 bridge; BSP can define which
195        bridge driver to use from VMEConfig.h.
196        Added 'err' macro parameter to BSP_VME_INSTALL_IRQ_MGR(err)
197        macro so that an error status can be passed back.
198
1992007-12-08      Till Straumann <strauman@slac.stanford.edu>
200
201        * irq_supp.h: was moved from shared/irq to
202        libcpu/powerpc/new-exceptions/bspsupport.
203
2042007-12-08      Till Straumann <strauman@slac.stanford.edu>
205
206        * ep1a/irq/irq.c, gen5200/irq/irq.c, gen83xx/irq/irq_init.c,
207        mbx8xx/irq/irq.c, mpc8260ads/irq/irq.c, mvme5500/irq/irq.c,
208        psim/irq/no_pic.c, score603e/irq/irq.c, shared/irq/irq_supp.h,
209        shared/irq/openpic_i8259_irq.c, virtex/irq/irq_init.c:
210        let C_dispatch_irq_handler() return zero to indicate to
211        low-level exception handling code that the exception
212        was handled (not used yet).
213
2142007-12-08      Till Straumann <strauman@slac.stanford.edu>
215
216        *shared/irq/irq_supp.h: removed cpp test for
217        BSP_SHARED_HANDLER_SUPPORT; BSPs using irq_supp.h
218        *must* implement shared handlers.
219
2202007-12-06      Till Straumann <strauman@slac.stanford.edu>
221
222        * shared/openpic/openpic.c, shared/openpic/openpic.h:
223        added routines to set timer period and interupt mask
224        and to read current count.
225
2262007-12-06      Till Straumann <strauman@slac.stanford.edu>
227
228        * virtex/irq/irq_init.c: use new ASM_xxx_VECTOR names.
229
2302007-12-06      Till Straumann <strauman@slac.stanford.edu>
231
232        * shared/vectors/vectors_init.c: replaced
233        switch ( current_ppc_cpu ) { } check by feature check.
234
2352007-12-06      Till Straumann <strauman@slac.stanford.edu>
236
237        * shared/irq/irq_asm.S, shared/vectors/vectors.S:
238        Replaced use of hardcoded PPC_EXC_MSR_BITS by a
239        run-time method to determine these bits (use settings
240        effective before exception occurred).
241        Replaced use of hardcoded ASM_VECTORS_CRITICAL by
242        'bsp_raw_vector_is_405_critical' variable.
243
2442007-12-05      Till Straumann <strauman@slac.stanford.edu>
245
246        * shared/irq/irq_supp.h: removed stray '*/'. Removed
247        inclusion of <stdlib.h> which is unnecessary and broke
248        if_dc in an obscure way (due to malloc/free redefinition
249        in the networking code).
250
2512007-12-05      Till Straumann <strauman@slac.stanford.edu>
252
253        * shared/irq/irq_asm.S, shared/vectors/vectors.S,
254        shared/vectors/vectors.h, shared/vectors/vectors_init.c:
255        Converted exception vector names to new ones
256        (qualified by <cpu_type> if non-std ppc exceptions).
257
258
2592007-12-04      Till Straumann <strauman@slac.stanford.edu>
260
261        * shared/startup/bspstart.c: export BSP_commandline_string
262        variable.
263
2642007-12-04      Till Straumann <strauman@slac.stanford.edu>
265
266        * shared/flash/flash.c: added lazy init of driver
267        from BSP_flashWriteFile().
268
2692007-12-04      Joel Sherrill <joel.sherrill@OARcorp.com>
270
271        * shared/startup/bspstart.c: Move interrupt_stack_size field from CPU
272        Table to Configuration Table. Eliminate CPU Table from all ports.
273        Delete references to CPU Table in all forms.
274
2752007-12-03      Joel Sherrill <joel.sherrill@oarcorp.com>
276
277        * shared/irq/irq.c: Spacing.
278
2792007-12-03      Joel Sherrill <joel.sherrill@OARcorp.com>
280
281        * shared/startup/bspstart.c: Moved most of the remaining CPU Table
282        fields to the Configuration Table. This included pretasking_hook,
283        predriver_hook, postdriver_hook, idle_task, do_zero_of_workspace,
284        extra_mpci_receive_server_stack, stack_allocate_hook, and
285        stack_free_hook. As a side-effect of this effort some multiprocessing
286        code was made conditional and some style clean up occurred.
287
2882007-12-03      Joel Sherrill <joel.sherrill@oarcorp.com>
289
290        * shared/irq/irq.c, shared/irq/irq_supp.h: Correct conditionals and
291        includes.
292
2932007-12-02      Till Straumann <strauman@slac.stanford.edu>
294
295        * shared/irq/i8259.c, shared/irq/irq.h, shared/irq/irq_supp.h,
296        shared/irq/openpic_i8259_irq.c: BSP_disable_irq_at_pic(),
297        openpic_disable_irq(), BSP_irq_disable_at_i8259s() now return
298        0/1 if irq was disabled/enabled prior to disabling.
299        irq_supp.h now exports a inline helper routine for scanning
300        a list of shared handlers; to be used by PIC drivers.
301
3022007-12-02      Till Straumann <strauman@slac.stanford.edu>
303
304        * shared/openpic/openpic.c shared/openpic/openpic.h,
305        shared/irq/irq_init.c: added more parameters to
306        openpic_init() so that more details of the configuration
307        can be overridden/set from the BSP. Moved setup of
308        the EPIC-specific EOI delay from BSP code into openpic_init()
309        using the new 'epic_freq' parameter.
310
3112007-12-02      Till Straumann <strauman@slac.stanford.edu>
312        * shared/openpic/openpic.c, shared/openpic/openpic.h:
313        - eliminated conditional compilation (#ifdef mpc8240)
314          The difference in register-layout between the EPIC
315          and the std. openPIC is handled by an offset parameter
316          which can be set at run-time (initialization) with
317          a new routine 'openpic_set_src_offset()'.
318        - allow BSP to define symbol BSP_OPEN_PIC_BIG_ENDIAN
319          which builds the driver for big-endian register access
320          (mpc8540).
321        - openpic_disable_irq() now returns the old state so
322          that it can be restored later.
323
3242007-12-01      Till Straumann <strauman@slac.stanford.edu>
325
326        * shared/irq/openpic_i8259_irq.c:
327        - conditionally define 'irq_mask_or_tbl' only if
328          BSP_PCI_ISA_BRIDGE_IRQ is defined.
329        - use _ISR_Get_level() / _ISR_Set_level() for re-enabling
330          interrupts rather than messing with MSR directly;
331          these macros:
332            o implement compiler memory barrier
333                o will handle multiple levels (e500 'critical' interrupts)
334                  if they are ever supported.
335        - decrementer irqs are also shareable - added list traversal.
336
3372007-12-01      Till Straumann <strauman@slac.stanford.edu>
338
339        * shared/irq/irq_supp.h: Make sure BSP_SHARED_HANDLER_SUPPORT
340        is set. The shared irq manager supports shared interrupts
341        (but requires also that the PIC-driver supports them by
342        traversing the list of shared handlers).
343        Declare C_dispatch_irq_handler() which must be defined
344        (like the other routines declared in this header) by the
345        PIC-driver.
346
3472007-12-01      Till Straumann <strauman@slac.stanford.edu>
348
349        * shared/clock/p_clock.c: (run-time) check for e500-cpu
350        and install different ISR for that type of CPU.
351
3522007-12-01      Till Straumann <strauman@slac.stanford.edu>
353
354        * shared/pci/detect_raven_bridge.c: use ifdef mvme2100
355        rather than ifdef mpc824x so that we don't depend on
356        compile-time CPU flavor. Eventually, this should become
357        a run-time check.
358
3592007-12-01      Till Straumann <strauman@slac.stanford.edu>
360
361        * shared/vectors/vectors.h: Give the BSP_Exception_frame
362        struct a name.
363
3642007-12-01      Till Straumann <strauman@slac.stanford.edu>
365
366        * shared/vme/vmeconfig.c: Include <libcpu/bat.h> only
367        if the BSP-specific configuration header (VMEConfig.h)
368        defines BSP_VME_BAT_IDX so that this file can be used
369        on CPUs w/o bats (e500).
370
3712007-11-30      Till Straumann <strauman@slac.stanford.edu>
372
373        * shared/startup/bspstart: removed _Cpu_table.exceptions_in_RAM.
374
3752007-11-30      Till Straumann <strauman@slac.stanford.edu>
376
377        * shared/startup/pretaskinghook.c: Replaced inclusion of
378        <bsp/consoleIo.h> by <rtems/bspIo.> (for printk) and
379        made it conditional on #ifdef SHOW_MORE_INIT_SETTINGS.
380
3812007-11-30      Till Straumann <strauman@slac.stanford.edu>
382
383        * shared/startup/bspstart.c: Removed excess /*, replaced
384        #ifdef checks for mpc8240 by #ifdef mvme2100; eventually
385        there should be run-time checks.
386
3872007-11-30      Till Straumann <strauman@slac.stanford.edu>
388
389        * shared/motorola/motorola.c: removed excess initializer
390        elements.
391
3922007-11-30      Till Straumann <strauman@slac.stanford.edu>
393
394        * shared/irq/irq.h, shared/irq/irq.c, shared/irq/irq_init.c,
395        shared/irq/irq_supp.h (added):
396        Removed 'is_processor_irq()' from irq.c; the BSP routines
397        BSP_enable_irq_at_pic()/BSP_disable_irq_at_pic() are required
398        to ignore processor irqs anyways. Removed
399        all BSP-defined constants from irq.c. This makes irq.c (almost)
400        binary-compatible among BSPs (ultimate goal is making 'shared'
401        a library).
402        Added a header (irq_supp.h) defining the interface between
403        the generic interrupt manager (irq.c) and the routines it
404        requires to be supplied by the BSP (eventually, these
405        should go into rtems/irq.h).

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

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

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

1244        This modification is part of the submitted modifications necessary
1245        to
1246        support the IBM PPC405 family.  This submission was reviewed by
1247        Thomas Doerfler <Thomas.Doerfler@imd-systems.de> who ensured it did
1248        not negatively impact the ppc403 BSPs.  The submission and tracking
1249        process was captured as PR50.
1250        * ChangeLog: Removed bogus comment on edit of generated file.
1251        * acinclude.m4: Added gen405 BSP.

1286        256 meg to allow operation on boards with larger RAM sizes.
1287        * shared/vectors/vectors_init.c: Modified to call 'generic' powerpc
1288        vector function (mpc60x_vector_is_valid) instead of MPC750  specific
1289        function to allow operation on boards with CPUs other than the
1290        MPC750.

1302        shared/startup/bspstart.c, shared/vectors/vectors.S,
1303        shared/vectors/vectors.h, shared/vectors/vectors_init.c: Per PR216,
1304        "libbsp/powerpc/shared" BSP has been modified considerably with the
1305        goal to make it more flexible and reusable by other BSPs. The main
1306        strategies were: - eliminate hardcoded base addresses; devices use
1307        offsets and a BSP defined base address. - separate functionality
1308        into different files (e.g. reboot from inch.c to reboot.c) which can
1309        be overridden by a 'derived' BSP. - separate initialization code
1310        into separate files (e.g.  PCI bridge detection/initialization was
1311        separated from the more generic PCI access routines), also to make
1312        it easier for 'derived' BSPs to substitute their own initialization
1313        code. There are also a couple of enhancements and fixes: - IRQ
1314        handling code now has a hook for attaching a VME bridge. - OpenPIC
1315        is now explicitely initialized (polarities, senses). Eliminated the
1316        implicit assumption on the presence of an ISA PIC. - UART and
1317        console driver now supports more than 1 port. The current maximum of
1318        2 can easily be extended by enlarging a table (it would even be
1319        easier if the ISR API was not broken by design). - fixed polled_io.c
1320        so it correctly supports console on COM2 - fixed TLB invalidation
1321        code (start.S). - exception handler prints a stack backtrace. -
1322        added BSP_pciFindDevice() to scan the pci bus for a particular
1323        vendor/device/instance.

1326
1327        * shared/startup/linkcmds: In support of gcc 3.1, added one of more
1328        of the sections .jcr, .rodata*, .data.*, .gnu.linkonce.s2.*,
1329        .gnu.linkonce.sb2.*, and .gnu.linkonce.s.*.  Spacing corrections and
1330        direction of segments to memory regions may also have been
1331        addressed.  This was a sweep across all BSPs.
1332
13332001-04-08      Joel Sherrill <joel@OARcorp.com>
1334
1335        * shared/startup/linkcmds: Per PR170, PR171, and PR172 add .eh_frame

1338
1339        * shared/Makefile.am, shared/console/consoleIo.h,
1340        shared/include/bsp.h: These modifications are part of the conversion
1341        of the mpc8xx CPU to the "new exception processing model."
1342        * configure.in, motorola_powerpc/Makefile.am,
1343        motorola_powerpc/configure.in: These modifications are in support of
1344        switching the mpc8xx to the use the "new exception processing
1345        model."

13562000-11-01      Joel Sherrill <joel@OARcorp.com>
1357
1358        * shared/startup/bspstart.c: assoc.h, error.h, libio_.h, libio.h,
1359        and libcsupport.h moved from libc to lib/include/rtems and now must
1360        be referenced as <rtems/XXX.h>.   Header file order was cleaned up
1361        while doing this.
1362
13632000-10-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

13682000-09-29      Charles-Antoine Gauthier <charles.gauthier@nrc.ca>
1369
1370        * shared/startup/linkcmds: Added lines so DWARF debug information
1371        would be available.  Otherwise gdb complains that the offsets for
1372        the debug info are incorrect and doesn't load the files.
1373
